As the hour approached for the arrival of the ladies, I saw that Mr. Engelman looked at me with an expression of embarrassment.

"Are you not going out this evening, David?" he asked.

"Am I in the way, sir?" I inquired mischievously.

"Oh, no!"

"In that case then, I think I shall stay at home."

He said no more, and walked up and down the room with an air of annoyance. The bell of the street-door rang. He stopped and looked at me again.

"Visitors?" I said.

He was obliged to answer me. "Friends of mine, David, who are coming to see the house."

I was just sufficiently irritated by his persistence in keeping up the mystery to set him the example of speaking plainly.

"Madame Fontaine and her daughter?" I said.
