The detective glanced keenly at him as he passed. He made a practice of glancing keenly at nearly everything. It cost nothing and impressed clients.
"I am so glad you have come, Mr. Sturgis," said Mrs. Pett. "Won't you sit down?"
Mr. Sturgis sat down, pulled up the knees of his trousers that half-inch which keeps them from bagging and so preserves the gentlemanliness of the appearance, and glanced keenly at Mrs. Pett.
"Who was that young man who just went out?"
"It is about him that I wished to consult you, Mr. Sturgis."
Mr. Sturgis leaned back, and placed the tips of his fingers together.
"Tell me how he comes to be here."
"He pretends that he is my nephew, James Crocker."
"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?"
"Exactly."
"Did he recognise him?"
"Yes. But wait. I have not finished. He recognised him, and for the moment I was satisfied. But I had had my suspicions of Skinner, too. I ought to tell you that I had been warned against him by a great friend of mine, Lord Wisbeach, an English peer whom we have known intimately for a very long time. He is one of the Shropshire Wisbeaches, you know."
"No doubt," said Mr. Sturgis.
"Lord Wisbeach used to be intimate with the real Jimmy Crocker. He came to lunch to-day and met this impostor. He pretended to recognise him, in order to put him off his guard, but after lunch he came to me here and told me that in reality he had never seen him before in his life, and that, whoever else he might be, he was certainly not James Crocker, my nephew."
She broke off and looked at Mr. Sturgis expectantly. The detective smiled a quiet smile.
"And even that is not all. There is another thing. Mr. Pett used to employ as a physical instructor a man named Jerry Mitchell. Yesterday I dismissed him for reasons it is not necessary to go into. To-day—just as you arrived in fact—the man who calls himself Jimmy Crocker was begging me to allow Mitchell to return to the house and resume his work here. Does that not strike you as suspicious, Mr. Sturgis?"
The detective closed his eyes, and smiled his quiet smile again. He opened his eyes, and fixed them on Mrs. Pett.
"As pretty a case as I have come across in years," he said. "Mrs. Pett, let me tell you something. It is one of my peculiarities that I never forget a face. You say that this young man pretends to have landed this morning from the Caronia? Well, I saw him myself more than a week ago in a Broadway cafe."
"You did?"
"Talking to—Jerry Mitchell. I know Mitchell well by sight."
Mrs. Pett uttered an exclamation.
"And this butler of yours—Skinner. Shall I tell you something about him? You perhaps know that when the big detective agencies, Anderson's and the others, are approached in the matter of tracing a man who is wanted for anything they sometimes ask the smaller agencies like my own to work in with them. It saves time and widens the field of operations. We are very glad to do Anderson's service, and Anderson's are big enough to be able to afford to let us do it. Now, a few days ago, a friend of mine in Anderson's came to me with a sheaf of photographs, which had been sent to them from London. Whether some private client in London or from Scotland Yard I do not know. Nor do I know why the original of the photograph was wanted. But Anderson's had been asked to trace him and make a report. My peculiar gift for remembering faces has enabled me to oblige the Anderson people once or twice before in this way. I studied the photographs very carefully, and kept two of them for reference. I have one with me now." He felt in his pockets. "Do you recognise it?"
Mrs. Pett stared at the photograph. It was the presentment of a stout, good-humoured man of middle-age, whose solemn gaze dwelt on the middle distance in that fixed way which a man achieves only in photographs.
"Skinner!"
"Exactly," said Mr. Sturgis, taking the photograph from her and putting it back in his pocket. "I recognised him directly he opened the door to me."
"But—but I am almost certain that Skinner is the man who let me in when I called on my sister in London."
"Almost," repeated the detective. "Did you observe him very closely?"
"No. I suppose I did not."
"The type is a very common one. It would be very easy indeed for a clever crook to make himself up as your sister's butler closely enough to deceive any one who had only seen the original once and for a short time then. What their game is I could not say at present, but, taking everything into consideration, there can be no doubt whatever that the man who calls himself your nephew and the man who calls himself your sister's butler are working together, and that Jerry Mitchell is working in with them. As I say, I cannot tell you what they are after at present, but there is no doubt that your unexpected dismissal of Mitchell must have upset their plans. That would account for the eagerness to get him back into the house again."
"Lord Wisbeach thought that they were trying to steal my nephew's explosive. Perhaps you have read in the papers that my nephew, Willie Partridge, has completed an explosive which is more powerful than any at present known. His father—you have heard of him, of course—Dwight Partridge."
