1:07:00
- You can't have it both ways.
- We must!
1:07:03
We owe it to Dorothy.
1:07:05
Eva, no.
1:07:06
You 're already the good-time girl and
the vicar's daughter.
1:07:10
Sheila, would you play the
housekeeper if I got you a wig?
1:07:13
Oh, Driffy, you make me sick.
You don't care about poor Dorothy.
1:07:18
All you care about
is your play and your stupid old self
1:07:21
and no, I won't play the housekeeper!
1:07:30
All right, Miss Marple.
Cyanide gas, but how?
1:07:34
- I think I can explain that.
- No doubt.
1:07:38
I take it from your tone that
you did not have second thoughts
1:07:42
about seeing
the Chief Constable yesterday.
1:07:45
- If you can explain, please do so.
- Very well.
1:08:08
Now!
1:08:11
So what? My wife has one.
1:08:13
Presumably
she doesn't cook candle wax.
1:08:15
No, she doesn't.
1:08:17
There is a little
at the bottom of that saucepan.
1:08:20
This is what happened.
1:08:22
The murderer set the dials
1:08:24
so that the gas
came on at 12:55 precisely
1:08:27
under this saucepan that
contained a small wax cup of acid
1:08:31
and a pellet of sodium cyanide.
1:08:34
The wax melted,
the acid flowed over the pellet.
1:08:37
Result: A sudden release
of cyanide gas. Lethal.
1:08:42
I see.
1:08:43
At one o'clock precisely,
the gas turned itself off...
1:08:50
...now!
1:08:52
Leaving nothing
but an innocent saucepan on the hob.
1:08:57
Yes. That means whoever we're looking
for must have specialist knowledge.
