eleven at night
He may have been a common burglar , or he may have had some private grudge against Mr. Douglas . Since Mr. Douglas has spent most of his life in America , and this shotgun seems to be an American weapon , it would seem that the private grudge is the more likely theory . He slipped into this room because it was the first he came to , and he hid behind the curtain . There he remained until past eleven at night . At that time Mr. Douglas entered the room . It was a short interview , if there were any interview at all ; for Mrs. Douglas declares that her husband had not left her more than a few minutes when she heard the shot . '' `` The candle shows that , '' said Holmes .
