"Your nephew? Have you never seen your nephew?"

"Never. I ought to tell you, that a few years ago my sister married for the second time. I disapproved of the marriage, and refused to see her husband or his son—he was a widower. A few weeks ago, for private reasons, I went over to England, where they are living, and asked my sister to let the boy come here to work in my husband's office. She refused, and my husband and I returned to New York. This morning I was astonished to get a telephone call from Mr. Pett from his office, to say that James Crocker had unexpectedly arrived after all, and was then at the office. They came up here, and the young man seemed quite genuine. Indeed, he had an offensive jocularity which would be quite in keeping with the character of the real James Crocker, from what I have heard of him."

Mr. Sturgis nodded.

"Know what you mean. Saw that thing in the paper," he said briefly. "Yes?"

"Now, it is very curious, but almost from the start I was uneasy. When I say that the young man seemed genuine, I mean that he completely deceived my husband and my niece, who lives with us. But I had reasons, which I need not go into now, for being on my guard, and I was suspicious. What aroused my suspicion was the fact that my husband thought that he remembered this young man as a fellow-traveller of ours on the Atlantic, on our return voyage, while he claimed to have landed that morning on the Caronia."

"You are certain of that, Mrs. Pett? He stated positively that he had landed this morning?"

"Yes. Quite positively. Unfortunately I myself had no chance of judging the truth of what he said, as I am such a bad sailor that I was seldom out of my stateroom from beginning to end of the voyage. However, as I say, I was suspicious. I did not see how I could confirm my suspicions, until I remembered that my new butler, Skinner, had come straight from my sister's house."

"That is the man who just admitted me?"

"Exactly. He entered my employment only a few days ago, having come direct from London. I decided to wait until Skinner should meet this young man. Of course, when he first came into the house, he was with my husband, who opened the door with his key, so that they did not meet then."

"I understand," said Mr. Sturgis, glancing keenly at the dog Aida, who had risen and was sniffing at his ankles. "You thought that if Skinner recognised this young man, it would be proof of his identity?"
