INSPECTOR. Quite so. This is just clearing the ground, sir.
WINSOR. General, d'you mind touching that bell?
CANYNGE rings a bell by the bed.
INSPECTOR. Well, gentlemen, there are four possibilities. Either the thief was here all the time, waiting under the bed, and slipped out after this gentleman had gone to Mr WINSOR. Or he came in with a key that fits the lock; and I'll want to see all the keys in the house. Or he came in with a skeleton key and out by the window, probably droppin' from the balcony. Or he came in by the window with a rope or ladder and out the same way. [Pointing] There's a footmark here from a big boot which has been out of doors since it rained.
CANYNGE. Inspector—you er—walked up to the window when you first came into the room.
INSPECTOR. [Stiffly] I had not overlooked that, General.
CANYNGE. Of course.
A knock on the door relieves a certain tension,
WINSOR. Come in.
The footman ROBERT, a fresh-faced young man, enters, followed by TREISURE.
