1:40:01
...exactly as you suggested,
Mr. Halliday.
1:40:03
He unlocked the door...
1:40:06
...then returned
the key before he came in.
1:40:09
And it's been
out there ever since.
1:40:12
And the key Wendice
took out of Swan's pocket...
1:40:15
-...and returned to her handbag was--
-Swan's own latchkey.
1:40:22
Mind you, even I didn't
guess that at once. Extraordinary.
1:40:25
You know, it had always puzzled me
that no key was found on Swan's body.
1:40:29
After all, most men carry
a latchkey about with them.
1:40:32
And then I had a brain wave.
1:40:35
I took the key
that was in your handbag...
1:40:37
...to his girlfriend's, Mrs. Van Dorn's,
and unlocked the door of her flat.
1:40:42
And then I borrowed her telephone
and called Scotland Yard.
1:40:46
-Why did you bring me here?.
-You were the only other person...
1:40:50
...who could possibly
have left that key outside.
1:40:52
I had to find out
if you knew it was there.
1:40:56
Suppose I had known?.
1:41:01
You didn't.
1:41:05
-Mark.
-Yes, darling?.
1:41:08
I think I'm going
to have that breakdown.
1:41:16
-Inspector Hubbard?
-O' Brien?.
1:41:18
Yes. He's just left the station.
1:41:20
Right.
1:41:27
Try and hang on just a little longer.
1:41:32
Williams, he's just left the station!
1:41:35
-Give me a thump if he comes this way.
-Do you have a handkerchief?.
1:41:38
What happens now?.
1:41:40
Sooner or later, he'll come back here.
1:41:42
As I've pinched his latchkey,
he'll try the one in the handbag.
1:41:45
When that doesn't fit,
he'll realize his mistake.
1:41:48
Put two and two together
and look under the stair carpet.
1:41:51
But if he doesn't do that,
all this is guesswork.
1:41:53
-We can't prove a thing.
-That's perfectly true.
1:41:56
But once he opens that door,
we shall know everything.
1:41:59
-What will you do then?.
-I'm to phone the home secretary.
