"I'm bound to say this bears out your theory, Mr.Barker.It looks as if the man got into the house after four when the curtains were drawn and before six when the bridge was raised.

He slipped into this room, because it was the first that he saw.

There was no other place where he could hide, so he popped in behind this curtain.

That all seems clear enough.

It is likely that his main idea was to burgle the house; but Mr.Douglas chanced to come upon him, so he murdered him and escaped." "That's how I read it," said Barker.
