"Do you mean to say that you and Rogers went away and left this stranger here by himself?"
"The servants' dining-room is right at the end of the hall, sir. We left the door open so that we could see right along the hall, clear to the front door. If he'd come out into the hall, we'd have seen him."
"And he didn't come out into the hall while you were there?"
"No, sir."
"Did anybody come in?"
"Oh, no, sir; the front door has a snap-lock. It can't be opened from the outside without a key."
"So you are perfectly sure that no one either entered or left the house by the front door while you and Rogers were sitting there?"
"Nor by the back door either, sir; to get out the back way, you have to pass through the room where we were."
"Where were the other servants?"
"The cook was in the kitchen, sir. This is the housemaid's afternoon out."
