:46:01
	FREDERICK: What's that, sir?
:46:03
	Want of feeling.
:46:05
	He knows everything about anatomy
and nothing about the soul.
:46:10
	How may I assist you, lnspector?
:46:12
	Forgive my ignorance, but...
:46:15
	...are you a surgeon?
:46:17
	I was.
:46:18
	Unfortunately,
I suffered a brain seizure six months ago.
:46:22
	-I'm sorry to hear that, sir.
-These days, I limit myself to teaching.
:46:27
	So you see, I'm accustomed to
answering questions, lnspector.
:46:35
	FREDERICK: Could you tell me
what sort of a knife this would be?
:46:45
	[Chuckles]
:46:46
	I think you mean to draw a Liston knife.
:46:49
	It's named for Liston,
who was a surgeon in the Crimean War.
:46:53
	Because there was
no anesthetic on the battlefield...
:46:55
	...he had to carry out
his amputations very quickly.
:47:00
	Do you, by any chance,
have the police surgeon's report available?
:47:03
	FREDERICK: Yes, I do, sir.
SIR WILLIAM: May l?
:47:06
	FREDERICK:
You must keep this confidential.
:47:08
	SIR WILLIAM: Of course.
:47:12
	Thank you.
:47:26
	[Coughs]
:47:28
	Wouldn't someone
have heard their screams?
:47:30
	Not if he cut their throats first.
:47:33
	Yes.
:47:35
	How can you be sure they wouldn't
react to seeing the Liston knife?
:47:39
	Grapes.
:47:42
	He offers them grapes first.
:47:45
	-Grapes are very tempting.
-They'd gobble them up.
:47:49
	He might offer them a drink
to ease them down.
:47:52
	A drink laced with laudanum.
:47:56
	SIR WILLIAM: How do you know that?
:47:58
	I found a sprig of grapes
on both victims' bodies.
