Yes, the house was not empty, as I had half feared.

A moment later a neat maid-servant opened the door, and regarded me with some surprise.

"Is Mrs. Petre at home?" I inquired.

"No, sir, she isn't," replied the girl with a strong East Anglian accent.

"When will she be in?" I asked.

"I really don't know, sir," she said. "She hasn't left word where she's gone."

"Is anyone else at home?"

"No, sir."

"How long have you been with Mrs. Petre?" I asked, adding, in an apologetic tone, "I hope I'm not too inquisitive?"

"I've been here about two months—ever since she took the house."
