♪♪

Ladies and gentlemen,
the future has arrived.

No more ironing shirts
on your kitchen table.

With the automatic
ironing board,

convenience comes
with the push of a button.

Automation is the future,
my friends.

Not one, not two,
but five cups of coffee

in the great coffee
distillation machine.

Ladies and gentlemen,
how many hours have you wasted

making you house a home?

With the paint dispenser,

you can cut your home
improvement in half the time.

No need to say,
"Pass the gravy."

With the tabletop waiter,

a flick of the wrist
brings the gravy to you.

Ladies, after a hard day
cleaning house,

there is nothing
you'll enjoy more

than the vibrating chair.

Why stand up
to turn on the lights?

With the wireless switch,
you can turn them on or off

from the comfort
of your very own chair.

It is a computer

in that it will perform
mathematical calculations.

However,
its architecture lends itself

to even more
complex computations.

Oh, is this
a miniature version

of Babbage's
analytic engine?

Well, the basic idea
was borrowed from Babbage, yes.

However,
by using Swiss gears,

I've constructed a computer
four times as powerful

in 1/40 the volume.

Oh, that must have been
very time-consuming.

Yes, it was, but it's my
belief that in the future,

the machine will be assembled
by automatons

who are themselves operated
by a device such as this.

Oh, thank you.

Mm-hmm.

This is the device for you.

Excuse me.

What is instant mail?

Oh, I'm sorry.

Ladies and gentlemen,

gather around
while I demonstrate to you

what will surely be
the most amazing device

that you will see all summer.

Has you child been smoking?

Has your wife been unfaithful?

Find out with the Truthizer.

Now, this gentleman has kindly
volunteered to participate

in a demonstration.

Sir, do you believe
your wife here

to be too fat?

Um, no.

Behold.

Clearly, that answer
was less than truthful.

George.

Sir,
what are you doing here?

I know what you
are going to say.

Before you say it, sir,
I think that your invention

simply must see
the light of day.

They are not inventions,
George.

They are simply reworkings
of existing technology.

Well, be that as it may, sir,
there are many investors here,

and some have shown
some real interest.

In fact, I think the Truthizer
might win the Eaton Prize.

- The Eaton Prize?
- Yes, sir.

The winner has their product
manufactured and sold

at all the Eaton stores.

It's very prestigious.

Nevertheless, George-.

Well, and, sir, also,
there is someone here

that you are going
to want to meet.

Who?

Alexander Graham Bell.

Alexander Graham Bell is here?

He is an inventor, sir.

His name wasn't on the list.

He was a last-minute addition.

Shall I show you where
his booth is?

No, no, George, not now.

I'm here to meet Karl Shreyer.

He left a message at the station
to meet here.

Oh, yes, Karl Shreyer.

He invented the suction cleaner.

The days of beating carpets
are over.

With the suction cleaner,

dust and dirt and sucked
into a special canister.

Thank you.

Excuse me.

Mr. Shreyer.

Detective Murdoch,
at last we meet.

How is it you know me?

An inventor always notices
the work of another.

Clearly a mind such as yours
is up to the challenge

of determining who sent this.

I found it on my table
this morning.

I believe it to be the work of
one of my jealous competitors.

My invention is clearly
going to win the Eaton Prize.

I see.

Ladies and gentlemen,

may I present Timothy Eaton?

[applause]

- Thank you.
- Thank you.

It is my pleasure each year
to announce the winner

of the Eaton Prize
for the most

commercially promising
invention.

This year,
the award goes to

the suction cleaner.

That's me.

Mr. Shreyer,
under the circumstances,

I would advise you not to go up
on that stage.

No, I have worked for years
for this moment.

I'm not going to be intimidated.

- Congratulations.
- Thank you.

[silence]

Did you hear that?

That was a dog whistle.

Human ears are not capable
of detecting such a pitch,

but that doesn't mean
the sound isn't there.

Ladies and gentlemen,

I have long felt like the sound
of that whistle,

reverberating alone
in the silence of ignorance.

Now, at long last,
my genius has been heard.

[crowd gasps]

Seal the exits, George.

This man has been murdered.

There was no gunshot?

None that was heard, sir.

Obviously,
something penetrated his skull.

As to how...

Must have been someone
who used one of those mufflers

that silences the gunshot.

How could someone use such
a weapon without being seen?

Could the shooter
have escaped?

The exits
were sealed immediately.

The killer is still
in the building.

We need to interview everyone,
where they were,

who they were standing with.

Yes, George is doing that now.

Sir,
is your tooth sore again?

A little bit.

Perhaps you
should see a dentist.

One of those
medieval torturers?

I'd rather face the Inquisition.

Carry on, Murdoch.

Do you have anything
for me yet, Doctor?

Well, this is strictly
preliminary, of course,

but I would hazard a guess
that the victim died

of a gunshot to the head.

Anything beyond the obvious?

The bullet didn't exit,

suggesting low muzzle velocity.

His eyes appear jaundiced.

I'm not sure why.

I suppose it's premature
to speculate

on the angle of entry.

The wound seems
perfectly circular,

suggesting perpendicular entry.

Which means the shot
would have come from above.

I think you would have noticed

someone hanging
from the rafters.

True.

With your permission,
Detective,

I'd like to remove the body
from the scene.

Yes, of course.

Thank you, Doctor.

Terrible thing
that's happened.

Alexander Graham Bell.

Mm, yes.

Detective Murdoch, I presume.

Yes.

Yes, I recognize you from
your photograph at your booth.

Please.

Actually,
it's not my booth.

My constable
took some liberties with...

I was particularly impressed
with your apparatus

for using sound reflection

to visualize
subsurface marine environments.

It's fascinating.

- Really?
- Mm-hmm.

I'd like to talk with you more
about it at some point.

Oh, after you've completed
your investigation, of course.

Of course.

Well, yes, certainly.

And the whistle that you have
in your hand,

confiscate it if you must,

but I would like it back
when you are finished with it.

What's so special
about a dog whistle?

Oh, it has a pitching screw
that enables one

to adjust the frequency,
very useful for some experiments

I was hoping
to conduct with Karl.

I see.

Were you
and Mr. Shreyer friends?

Oh, not friends, no.

I don't think Karl was capable

of genuine friendship
with anyone.

But we certainly
weren't adversaries,

which makes me something
of a rarity in this crowd.

Well,
who were his adversaries, then?

I hated him.

I admit it freely.

Why is that, Mr. Nellis?

He ridiculed
my tabletop waiter.

He told me that it was
an invention

worthy of a five-year-old.

But I wasn't the only one
who hated him.

I saw him have a fistfight
with Harding.

It wasn't exactly a fistfight.

Then how would you
describe it, Mr. Harding?

Mm, a lot of arms
flailing about.

Neither of us were exactly
pugilists.

It was all rather pathetic,
actually.

So why the dustup?

Shreyer changed
the setting of one of my gears.

It threw off
all my calculations.

It took me six hours to find
which gear had been compromised.

Why would he do
something like that?

Well,
he was very competitive.

He once sabotaged Barton's
automatic ironing board

so that it wouldn't open,

and Jeremy was showing it
to investors at the time.

Disconnected
the internal switch.

He all but admitted it.

I would never raise a hand
to hurt anyone, even Shreyer,

but if wishes could Kill,

he would have been dead
a long time ago.

You hated him that much?

Oh, we all did.

Sabotage was the least of it.

He was also a spy.

His prize-winning invention?

He stole the concept
from O'Brian.

At last year's convention
in New York,

I suggested that a fan
placed behind a strip of gauze

could create a vacuum
strong enough

to lift the dirt out of a rug.

It's a million-dollar idea.

It's a million-dollar idea.

Did you tell Karl Shreyer
about it?

No, but I did send imail
about it

to some of the other inventors,
who sent back improvements.

Imail?

- Instant mail.
- It's Myrtle Raylin's invention.

We use it to communicate
back and forth

between conventions.

And it's your belief
that Karl Shreyer

got a hold of these
communications?

It got so bad, we had to start
imailing each other in code.

The typeface of this imail

matches that
of the death threat.

So you think the death threat
was printed

on one of the imail machines.

- I do.
- Hmm.

Thank you for agreeing
to do this.

Oh...

I hope you don't think me
presumptuous,

but as both the son and husband
of deaf women,

you're the only person I know
who reads sign language.

Hmm.

I do it with reluctance,
I'm afraid.

Oh?

Yes, you see, it's my belief
that deaf people

should learn to articulate
audible speech.

I've tried to get Myrtle
to learn,

but she's very stubborn.

Does she read lips?

Oh, yes,
more than she lets on.

Instant mail is a process
of sending letters instantly

anywhere in the world.

How does it work?

A letter is typed.

The information is recorded
onto a wire cylinder.

At the push of the "send" key,

a message is sent
over the telephone lines

to the intended recipient.

Oh.

Um...

I believe that this message
was printed

using one of your machines.

Who has these machines?

She sent units
to each of the inventors

she was closest to.

I don't think Karl
ever received one.

Why was that?

She disliked him.

Oh, she detested him.

Why?

He once declared
his amorous intentions

rather inappropriately.

When she rejected his advances,
he became vile and abusive.

He insulted her femininity
and mocked her deafness

and said that instant mail
wasn't really an invention

at all but merely a reworking
of Edison's stock ticker.

Stock ticker.

That was good, Myrtle.

You should speak more.

So that message
could have been printed

on any one of the machines
you distributed?

Yes.

Mm-hmm.

Would there be a record
of the last message sent

on the machine
that sent that message?

Oh, yes.

Each machine can retain
up to 20 messages, depending,

of course,
on the length.

Oh, that's good.

Mm-hmm.

That's very good.

The bullet struck the left,
upper portion

of the frontal bone

roughly perpendicular
to the curvature of the skull.

It then traveled
in a downward trajectory

and lodged inside
the right temporal lobe.

So the bullet did come
from above.

That would seem
to be the case.

I also managed
to extract the bullet.

You recognize this?

It's a ball bearing.

Yes, the same kind you use
in your Tabletop Waiter.

Indeed, it is,
nickel-plated, high-quality,

imported especially
from Bern, Switzerland.

You may have noticed
the rotational smoothness.

Why do you ask?

It was the projectile
used to kill Karl Shreyer.

How do you explain that,
Mr. Nellis?

Well, obviously, someone is
trying to cast suspicion on me.

I mean, why would someone
use a ball bearing

when a regular bullet would do?

Mr. Nellis, where were you
when the shot was fired?

I was watching the speech.

Who were you standing with?

Your constable
already asked me this.

I don't remember.

You think he might
have been set up?

It's possible.

His point is well-taken.

Why use a ball bearing if not
to implicate him in the murder?

Well,
I read the statements.

All the inventors seem to hate
this Shreyer fellow.

Question is,
which one do you think did this?

The death threat was sent
using one of Miss Raylin's

instant mailing machines.

George and Henry
are reading the imails now.

- Imails?
- Instant mailings.

Sir, is that cocaine?

Mm, this bloody tooth.

Helps to numb the pain.

Are you sure that's wise?

Don't you start on me,
Murdoch.

Sir, I have nothing against

the use of cocaine
as a topical analgesic,

but given your history
with the drug...

There you are, Thomas.

Oh, bloody hell.

I'll speak to you later,
Sir.

Where were you at 2:00
this afternoon?

Hello, dear.

You were supposed
to be at the dentist.

I had duties to attend to,
Margaret.

Thomas,
don't be a baby about this.

We're trying to solve
a murder here.

I can't be spending half my day
gallivanting off to the dentist.

Well, I've made another
appointment after work,

and I'll be back here
to escort you to it.

I can hold your hand
if need be.

I'm not a child,
Margaret.

After work.

Higgins.

Sir,
we've printed off the imails.

They're gibberish mostly.

Yes, apparently,
they were encrypted

to keep Karl Shreyer
from reading them.

The only exception
was the death threat.

Which machine was this one
printed on?

Mr. Bell's, sir.

Alexander Graham Bell.

I'm sorry, sir.

I know he's something
of an idol.

Bring him in, George.

That message was written
on your instant mail machine.

That may very well be,

but if you're looking
for the author of that note,

I'm afraid it isn't me.

Then how did it come
to be written on your machine?

Well, someone must have gone
into my booth

when I wasn't there.

It would have been easy.

Where were you at the time
of the shooting?

I was recording the speech.

Recording?

- Mm.
- Why?

Well,
Karl had asked me to...

provided he'd won,
of course.

[laughs]

You mean you have a recording
of the speech

and the moment he was shot?

Mm.

Would you like to hear it?

Karl wanted a permanent record
of the moment

when he bested the competition.

He was vainglorious.

As much as he was
detested by others,

he had a very high opinion
of himself.

If he was so disagreeable,
why agree to make the recording?

Well, he agreed to blow
the dog whistle,

and I wanted to test
the frequency limits

of my recorder.

Why not simply conduct
a controlled experiment?

Well, he refused
to relinquish possession.

But I thought
it was your whistle.

Yes, I had one just like it,
and I lost it

about the same time he came
into possession of his.

You think he stole it.

You're the detective,
Detective.

I find it hard to believe that
someone could be that petty.

Oh, I think I understand.

You know how some men
are born with natural charm?

You just can't help
but like them.

Of course.

Well,
Karl had negative charm.

No matter what he did,
people didn't like him.

Rejection can make a man bitter,

which in turn makes him
even more disliked.

A vicious circle.

Mm, yes.

Let's have a listen.

Ladies and gentlemen,

I have long felt like the sound
of that whistle,

reverberating alone
in the silence of ignorance.

Now, at long last,
my genius has been heard.

[light clicking noise]

[crowd gasps]

I can't make out
anything definitive.

I only hear the sound
of the crowd.

You know, Detective,
to paraphrase Karl,

just because
we can't hear a sound

doesn't mean it's not there.

Allow me to introduce you
to my latest invention.

I call it an audiograph.

I developed it
to help deaf people

visualize the sounds
that they were making.

You see, it converts sound
into a signal

and then traces the wave
on paper

much like your graphizer.

Well, yes,
but the difference is,

you've isolated
certain frequencies.

Oh, well, yes.

Ladies and gentlemen,

I have long felt like the sound
of that whistle,

reverberating alone
in the silence of ignorance.

Now, at long last,
my genius has been heard.

[light clicking noise]

[crowd gasps]

So his speech
lasted 18 seconds.

And here is where the noise
of the crowd rises sharply

in reaction to his death
about two seconds later.

So the bullet would have been
fired between here and here.

- Mm-hmm.
- Well, this is interesting.

Look how the amplitude
of the highest frequency spikes

at the precise moment
that he was shot.

Yes, it raises sharply
and then falls off.

Like a bell ringing,

as if the bullet
hit something metallic.

Well, if it did
and that's what I think it is,

it would explain why we saw
nothing in the rafters.

Both:
The bullet was deflected.

A bit higher, Constable.

Higher.

There.

So the metal surface that we
directed the projectile

was that steel beam.

It has to be.

Now all we have to do
is match the angle of incidence

to the angle of reflection.

Sir, have you noticed
anything different

about the inspector of late?

He has a toothache?

Well, yes,
I know about the tooth,

but it's more his behavior
I'm worried about.

One minute, he's edgy,
cantankerous,

and then the next minute,

he's full
of backslapping bon ami.

It's almost like-do you
remember a couple of years back

he was taking that gold cure?

Yes,
it turned out to be cocaine.

Well, now he's rubbing cocaine
on his gums

as an analgesic for his tooth.

I'm afraid
that he's gonna have...

what do they call it?

A relapse.

I share your concern, George,
but he's seeing a dentist today.

Hopefully the situation
will be rectified.

Hmm.

Oh, that's odd.

The shooter would have had to
have been standing

much further back.

But, sir,
if he was standing farther back,

this sign would have been
in his way.

Indeed.

Unless, of course,
the shooter was standing

in front of the sign...
if he was tall...

extremely tall.

I suppose we would have noticed
a giant with a weapon

in the back of the room.

There's another possibility,
George.

I'm going to need a wrench.

Do what you have to do,
Doc.

Let's get this over with.

Oh, good for you, Thomas.

[knock at door]

My apologies for interrupting.

It's Detective Murdoch, sir.
He needs you right away.

Bloody hell.

Can't this wait?

He was quite insistent,
Sir.

Oh, sorry, Doc.

We'll have to do this
another time.

Margaret,
schedule another appointment.

What's the panic this time,
Higgins?

So how was that, sir?

Perfect, bloody perfect.

Cracking fine job, Higgins.

- Thank you, sir.
- Can I treat you to a pint?

Yes, sir.

George Crabtree?

- Yes.
- What can I do for you?

I want that Truthizer
you've invented.

Well, now,
I didn't exactly invent it.

So you don't hold the patent?

It's pending.

Well, what would it take
to buy it from you, then?

I suppose I would have
to speak with my partner.

Well, why don't you let me
talk to him?

No, no, no, no, it's best
if you speak with me.

I'm the people person.

He's-he's a temperamental sort.

My offer
to come to terms with you

is only available for 24 hours.

Only 24 hours?

I don't sit around waiting

for money to come to me,
Mr. Crabtree.

I go after it.

Uh, sir, good news.

We have an investor interested
in the Truthizer.

George,
all the Truthizer does

is measure an increase
in heart rate.

It's only value
is in telling the liar

that we know they're lying.

Which is exactly what makes it
such an essential tool

for law enforcement.

George-.

Sir, why should we be
the only station

to have such an instrument?

I believe it is
our responsibility

to put it out into the world.

Criminals everywhere will be
quaking in their boots

if they know we could look into
their guilty minds,

not to mention
what a profit we could make

from such a venture.

Fine, George.

I authorize you to speak
to an investor on our behalf.

Oh, excellent, sir.

I am very excited.

Mm.

What is it?

I have no idea.

This is a battery.

There are wires leading
to a switch of some sort,

but then this appears to be
a switch as well.

I'm going to bypass
these switches

to see if I can figure out...

[mechanical clicking]

[gunshot]

I believe we've found
our murder weapon, George.

So this thing fired a ball,

which was then redirected
by a chunk of metal

towards Shreyer's head.

Hence the need
for a projectile

with complete
angular uniformity.

A ball bearing.

Yes.

Well, just say that then.

Why do you always dress up
simple concepts in $5 words?

Did the doctor yank
your tooth?

No, he couldn't.

An emergency intervened.

No worries.

It will clear itself up
eventually.

So this ball bearing fellow
Nellis, is he our man then?

It's possible.

Sir, have a look at this.

Note the similarities between
the device and this invention.

Who built that then?

Jeremy Barton.

Well, bring him him.

Well, not so fast, sir.

This is O'Brian's
wireless switch.

A similar switch is used
inside the device

to trigger it remotely,
I suspect.

- Bloody hell.
- So O'Brian built it.

Ah.

Sir, you see these gears?

They are the same
as the gears used

in Harding's
miniature analytic engine.

Let me guess.

He didn't build it either.

Sir, I suspect that this
is a collaborative effort

using the expertise
of five different inventors.

You've only mentioned
four so far.

Oh, I suspect Myrtle Raylin
is also involved.

The deaf woman
who invented the-.

What do you call it?

Both: Imails.

Yes, sir.

A project like this would
require extensive coordination

and communication
over great distances.

Coded imails would fit the bill.

Myrtle Raylin wrote
all of the codes.

There's only one thing
that troubles me.

What's that?

O'Brian's wireless switch.

It doesn't actually
activate the device.

[clicking]

Even though his switch
is inside.

Well, yes, sir.

There's another primary switch.

A switch that turns
on a switch?

What the hell for?

I have no idea,

but I suspect there's yet
another inventor involved.

Maybe it's your pal
Alexander Graham Bell.

I have no reason
to suspect him.

Not yet.

Your ball bearing wasn't used
to frame you, Mr. Nellis.

It wasn't?

It was used as a component
in a plot to kill Karl Shreyer.

Plot?

Oh, ridiculous.

Then how do you explain
the use of your invention

as a component in the device
that killed him?

Someone else must have
put it there.

It wouldn't be difficult.

It's just a switch.

You must admit,
it bears a strong resemblance

to what you invented.

Well, whoever built this
obviously copied my design,

but this is
so much more complex.

Are those Harding's gears?

Mr. Harding?

Yes, they are.

And it seems that
in this device,

they act more
of a delay mechanism.

However, they do still serve
as the central control.

It's just in a machine
like this,

it doesn't require
a logical complexity.

Of course, your invention
doesn't suggest

an aptitude for complexity.

Now, see here.

- Pardon me?
- Oh.

Could you have built
this device yourself?

No.

Perhaps if I applied myself.

No.

No.

Of course I could have.

Well, I didn't,
but I could have.

It is my belief
that each one of you

contributed to the design
and construction of this device.

And that makes you all
equally guilty of murder

in the eyes of the law.

Now, the first one of you
to admit their complicity

in this scheme
will be spared the noose.

Everyone else, however,
I guarantee you will be hanged

by the neck until they are dead.

So I ask you once again,

were you or were you not
part of a conspiracy

to kill Karl Shreyer?

No.

Of course not.

No.

Mr. Harding.

Huh?

Oh, no.

May I stay and study this?

Could any one of them
have built this by themselves?

Harding, possibly,
but he admitted it so freely.

Would a guilty person
be so guileless?

Only if his guilelessness
was an act.

Sir,
are you all right?

Oh, I'm fine.

The heroin
has knocked me back a bit.

Heroin?

The cocaine wasn't quite
doing the job.

This new drug works wonders,
Murdoch.

Oh, yes, I'm sure heroin
is very effective, sir,

but it's new.

It could prove to be
just as addictive as cocaine.

It's only till the toothache
goes away, Murdoch.

Now, if you don't mind,

I think I'm gonna have
a bit of a nap.

[snoring]

Sir, we've been deciphering
the imails

we got from Miss Raylin
with her code wheel.

Oh.

How does it work?

The number of letters
in the sender's first name

added to the number of letters
in the day the message was sent

gives you the offset.

Offset?

Yes, say Myrtle
sends a message on Thursday.

Six letters in "Myrtle,"
eight letters in "Thursday."

Eight plus six gives you...

- 14.
- 14.

So the offset is then 14.

Ah, so "A" becomes "N"
and so on.

That way, the code changes
every day with every sender.

That's very clever.

Mm, now, it didn't work
for all of them.

This one particular imail
was different.

Who sent this one?

Miss Raylin,
we were unable to decipher

one of the imails that you wrote
to the other inventors.

It was sent on Tuesday.

[machine clacking]

"This does not conform
to the code."

That's right.

Can you tell me why that is?

Uh...

This was only written
four days ago

shortly after
the invention convention began.

Do you remember what you wrote?

[machine clacking]

I think this is
a specially coded message

written to the other inventors

outlining the plot to kill
Karl Shreyer.

[sighs]

[machine clacking]

This isn't one of our ciphers.

How do you know?

Oh, I've learned
to see letters as numbers.

"A" is "1 MM.

"B" is "2."

Then in a standard cipher,
the letters shift,

but the numerical relationship
between them stays the same.

And you're able to recognize
these patterns?

Oh, yes.

Yeah, it's easy.

I always look
for the word "the."

"T" is always 11 letters
from "H."

"H" is always four letters
from "E."

But I think you'll find
that there's no such sequence

in this message.

Therefore, whoever wrote it
was using a more complex cipher.

You think it would be possible
to use your mechanical analyzer

to break this cipher?

Well,

I supposed I'd have to...

It's a straightforward,
logical looping.

And I'd have to assign
each letter to a number.

Well,
if it's too difficult-.

No, no, no, no.

It's absolutely possible.

When can we begin?

The machine's instructions
are punched in cardboard.

Like Jacquard's loom.

Exactly.

I'm telling the machine to
execute a repeatable calculation

that will shift forward
with every loop,

and that should test
every possible sequence.

How long will that take?

Oh, no more than a couple
of hours.

[machine clacking]

[sighs]

I just don't understand it.

I've tried every
linear combination.

I mean, I could try
a more complex routine,

but I just doubt that anyone
would go to the trouble

of deciphering such a code,
unless...

Unless what?

Unless it's a random code.

- Random?
- Random.

There is no
numerical relationship.

Each letter is just randomly
assigned to another letter.

Can you crack such a code?

Well, yes, but
the possible combinations are...

I-this is an N factorial
calculation, Detective.

26 times 25 times 24-.

- Is it possible?
- In theory.

But the possible permutations
are in the trillions,

in the quadrillions.

So you can't do it.

No.

I can't do it.

- So could it be this...
- what do you call it?

Random cipher.

I don't know.

It would require the sender
and the receiver

to memorize a 26-letter code.

Mm,
that wouldn't be easy.

No, you're right, sir,
too prone to error.

Must be something else,
something more simple.

[exhales]

Well, I'm sure you'll figure
it out, Murdoch.

[sighs]

But I always look
for the word "the."

Areoccurring grouping
of three letters.

Three letters.

George.

George,
I've cracked the code.

Have a look.

Arrest them.

Arrest them all.

"We have precisely 20 seconds

"between when the device
is triggered

"and when the shot is fired.

"Should the machine
be discovered,

"it is imperative that we stick
to the plan.

We must hang together,
or we all hang separately."

Well, that proves it.

But, sir, they're all sticking
to their story.

Sir, this is
the perfect opportunity

to demonstrate our Truthizer
to our investor.

Your investor, George.

Perhaps he's got a point.

If they know that we know
that they are lying.

One of them just might...
just might crack.

[snoring]

Your arm, please.

Now, watch it in action,
Miss Dickinson.

We know for certain
that they're guilty.

Now, as they engage
in their prevarications,

their guilty mind
will cause the blue fluid

to rise in the tube.

I, of course,

know how the apparatus works,
Mr. Crabtree.

Otherwise,
I would not be here.

Yes, right, of course.

So how does this work,
then?

Did you receive this imail?

No.

Oh, I see.

It responds to a change
in the heart rate.

Very clever.

Did you or did you not
send this imail?

I did not.

And then the resulting change
in pressure

drives liquid up the tube.

Fantastic.

Please,
just answer the question.

I did not.

May I buy this from you?

I ask you again,

did you or did you not send this
imail to your coconspirators?

[typewriter keys clacking]

- [sighs]
- That's it.

I'm out.

Wait, you should let me
show you a pair

of Detective Murdoch's
night vision goggles.

They're-.

Good-bye, Mr. Crabtree.

So now you think
they're all innocent.

I don't know what else
to think, sir.

We know at least one other
inventor was involved,

the man who designed
the primary switch.

The switch that turns on
the switch.

Yes, I've seen nothing like it
in any invention, sir.

I only know it's a switch
because of the way

it's wired to the device.

You think this person built
the device,

then constructed an elaborate
code to frame everyone else.

It's a possibility.

Now I just have to figure out
how to activate the switch.

Time to go, Thomas.

Ah, right, right.

Higgins.

Good luck, sir.

[knock at door]

Some mail, sir?

Precisely 20 seconds,
George.

What's that?

20 seconds from the time
the device was activated

to the time it fired the shot.

What happened 20 seconds prior

to the shot being fired?

Well, Shreyer was giving
his speech, sir.

His speech was 18 seconds.

What happened 2 seconds
before he started to speak?

Well,
he blew his dog whistle.

[silence]

[clicking and whirring]

[gunshot]

Well, he agreed to blow
the dog whistle,

and I wanted to test
the frequency limits

of my recorder.

George,
arrest Alexander Graham Bell.

[horse whinnying]

Higgins.

What are you doing here?

I don't think
I'm supposed to say.

Does this have anything to do
with the inspector?

When he taps twice
on the window,

I'm gonna go in and say
there's been an emergency

and that he's needed.

- Avoiding the dentist, is he?
- Mm.

Higgins, Detective Murdoch
has asked that you arrest

Alexander Graham Bell
at his hotel.

I can't.

I'll take care
of your duties here.

Well,
why can't you arrest him?

Oh, Higgins,
I'm not a mind reader.

I can't read
the detective's mind.

He said,
"George, find Henry.

"Have him arrest
Alexander Graham Bell.

He's at the Queens Hotel."

Right away.

Why are you always
knocking on windows?

That's just my way of saying,
"Let's get on with this."

Do your worst, Doc.

Sir...

Crabtree.

I just wanted to update you
on the status of the case.

- Oh, well, I'd better come.
- That's not necessary, sir,

but you should know
that we printed the imails.

Oh, well,
I should take a look.

Again,
that's not necessary, sir.

The only damning one came from
Alexander Graham Bell's machine.

Oh, well,
we'd better arrest him.

And that's what we're doing,
Sir.

I've sent Higgins.

Higgins?

Higgins?

He seemed the right man
for the job, sir.

Best of luck with the tooth.

[screams]

What is this?

A sonic switch.

More accurately,
a harmonic switch,

which is activated
at the precise frequency

of 18,000 cycles per second,

conveniently the same frequency
as your dog whistle.

It was an ingenious plan:

Build a sonic switch
into a device

and have Karl Shreyer
trigger it himself.

Brilliant.

Wh-Why would I kill Karl?

I was the only one
that didn't hate him.

So you made sure to tell me

and then proceeded
to insinuate yourself

into my investigation.

You invited me.

Oh, did I?

As I recall,
it was you who approached me

and then told me about
Karl Shreyer's many enemies.

It was you who told me
about the audio recording

and volunteered your audiograph
to help me analyze it.

So I helped you,
and that makes me guilty?

You manipulated me so that I
wouldn't come to the conclusion

that I now have.

And what is that?

That you built it using parts
from many different inventors

so that it would appear
that many different inventors

conspired to kill Karl,
but it was you all along.

By myself?

You were the only inventor
at that convention

capable of building
such a device.

You were certainly the only
inventor capable of building

a sonic switch.

But, Detective,
why would I do this?

Why would I kill Karl?

Why would I go
to so much trouble

to frame my fellow inventors,

people whom I respect
and admire?

Then how do you explain
the fact that the device

was trigged by a whistle
you asked Karl Shreyer to blow?

Detective, I didn't ask Karl
to blow the whistle.

He suggested it
as part of his speech.

Why would he do that?

Unless...

Dr. Grace, have you completed
your postmortem?

I have.

Did you find anything unusual?

As a matter of fact,
I did.

I determined the cause of death
to be a gunshot to the head,

and normally I would have
concluded my postmortem

at that point.

But as you might remember,

I noticed that his eyes
were jaundiced.

Yes.

Which is caused by an excess
of bilirubin.

In newborns, it's quite normal,
but in adults-.

Doctor,
if you could get to the point.

Yes, yes.

I dissected the liver,
and that's where I found it.

Found what?

The tumor was as large
as my fist.

So Karl Shreyer was dying.

He had a month or two at most.

He would have been
in quite some pain.

I don't know if any of this
is relevant.

[clicking and whirring]

[gunshot]

Actually, Doctor, you've
helped to confirm my theory.

Thank you.

Are you telling us
that Karl made this?

And then used it
to kill himself?

Is it patented?

I believe he built
the device himself

using knowledge he gleaned
from his spy...

So that's what he was doing
all this time.

And then sent coded imails
to make it appear

you were all conspiring
to kill him.

Bastard.

He sent us to hang?

- So it would appear.
- And wait a minute.

All of this is contingent on you
finding the device

and deciphering the code.

How would he know
that you would succeed?

Well, I imagine he knew
Detective Murdoch by reputation.

I mean, he did ask specifically
for you, did he not?

He did, yes.

But then why would he assume
you wouldn't figure it out,

as you so clearly have done?

I suppose that was
a calculated risk.

Or maybe it didn't matter.

Maybe all he wanted
was to force us

to acknowledge his genius.

May I?

[silence]

[clicking and whirring]

Well, he was that,

a genius.

Which one of us
could have made this?

Oh, I could have.

[gunshot]

Be careful with that,
Worseley, now.

That's somebody's invention.

Crabtree.

How was the dentist,
sir?

Worst pain
I've ever experienced.

I'm sorry to hear that,
Sir.

How does your tooth feel now?

Better.

I suppose I have you
to thank for that.

Oh, sir, no thanks necessary.

You've got guts, Crabtree.

Not much in the way of brains,
but you do have guts.

- Oh, thank you, Detective.
- It's nice to have it back.

Thank you.

I don't think I could have
solved this without your help.

Oh,
I doubt that's true.

And I'm sorry for accusing you
the way I did.

Oh, now, I'd have done
the same in your shoes.

Good-bye, Mr. Bell.

You know, I'm staying in
Toronto for a couple of weeks.

We should go for dinner.

Inventors need to talk
to other inventors.

Oh, of course.

All right.

[knock at door]

George.

[sighs]

I understand your investor
backed out.

She was convinced
the Truthizer didn't work.

Well, ironically,
it did work.

Oh, I know.

This is quite
the invention, sir,

creating a sound
to activate a switch.

Imagine if one day you could
switch the lights on by...

I don't know-
Clapping your hands.

Well, it would be brilliant
for the bedridden

or the infirm
or just the unusually lazy.

Well, maybe you
should invent it, George, hmm?

Perhaps I will.
