The Father [to The Servant]. No one came in just now?

The Servant. No, sir.

The Father. But we heard someone open the door!

The Servant. It was I shutting the door.

The Father. It was open?

The Servant. Yes, sir.

The Father. Why was it open at this time of night?

The Servant. I do not know, sir. I had shut it myself.

The Father. Then who was it that opened it?

The Servant. I do not know, sir. Someone must have gone out after me, sir....
