All language subtitles for Murdoch Mysteries - S05E09 (EN)

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 your 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 Schreyer.

He left a message at
the station to meet here.

Oh, yes, Karl Schreyer.

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. Schreyer.

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?

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. Schreyer, 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.

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.

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. Schreyer 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. Nellie?

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?

Schreyer 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 Schreyer,

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'Brien.

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.

Did you tell Karl Schreyer about it?

No, but I did send mail 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 Schreyer

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 Schreyer.

How do you explain that, Mr. Nellie?

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. Nellie, 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 Schreyer 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 Schreyer 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.

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.

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.

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.

Mmhmm. 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.

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.

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-

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 Schreyer'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
Nellie, 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.

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'Brien 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?

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.

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. Nellie.

It wasn't?

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

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.

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 Schreyer?

No.

Of course not.

No.

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.

Sir, we've been deciphering the imails.

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.

"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?

I think this is a specially coded message

written to the other inventors

outlining the plot to kill Karl Schreyer.

This isn't one of our ciphers.

How do you know?

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

"N. 'S u.'
-..

"B" is "Z."

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" is always four letters from.

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.

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.

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

But I always look for the word "the."

A reoccurring 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.

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.

L, 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 co-conspirators?

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.

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, Schreyer 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.

Well, he agreed to blow the dog whistle,

and I wanted to test the frequency limits

of my recorder.

George, arrest Alexander Graham Bell.

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?

He seemed the right man for the job, sir.

Best of luck with the tooth.

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 Schreyer 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
Schreyer'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 triggered by a whistle you
asked Karl Schreyer 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 post-mortem?

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 post-mortem

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 Schreyer 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.

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?

Well, he was that,

a genius.

Which one of us could have made this?

Oh, I could have.

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.

George.

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.
