“Oh! I suppose you mean Miss Thurston—the young American lady, don’t you? But she’s fair-haired!”

“The lady I mean is named Engledue,” I replied.

“Oh! I don’t know anyone of that name,” was his reply. “Miss Thurston has stayed with us in London and down in Cornwall, and has been here several times. I fancy she’s some relation of the mistress’s. She first came to stay about three years ago, when she left school in Paris. Then she went home to America, and after six months came back again to us.”

“You haven’t any idea who her parents are—or where she lived in America?”

“She lived somewhere near Detroit, I believe. That’s all I know about her. I believe her people are motor-car makers and extremely wealthy. At least, somebody said so—and she’s very free with tips to the under-servants.”

“When did she leave here?”

“When the master went to London. I was to go too, but I had influenza and had to remain here.”

“And where was Mrs. De Gex?” I inquired.

“She was already at Stretton Street. She and the little boy went to London early in October, but came back at the end of the month.”
