But I was already in my dressing-gown, and groping for my clothes. "No, no, come in and tell me," I said. "What is it?"
Hewitt sat on the bed. "I'll tell you in due order," he said. "First, I saw Samuel again last night—after you had gone away. You remember I went back to my office; I had a letter or two to write which I had set aside in the afternoon. Well, I wrote the letters, shut up, and went downstairs. I opened the outer door, and there was Samuel, in the act of ringing the housekeeper's bell. He said he was very anxious, and couldn't sleep without coming to hear if I had made any progress; he had called before, but I was out. I half thought of taking him back to my office, but decided that it wasn't worth while. So I walked along to the corner of the Strand, till I got him well under the lights. Then I stopped and talked to him. 'You ask about the progress in your case, Mr. Samuel,' I said. 'Now, I have sometimes met people who seem to consider me a sort of prophet, seer, or diviner. As a matter of fact, I am nothing but a professional investigator, and even if I were possessed of such an amazing genius as I lay no claim to, I could never succeed in a case, nor even make progress in it, if my client started me with false information, or only told me half the truth. More, when I find that such is the state of affairs, and that if I am to succeed I must begin by investigating my client before I proceed with his case, I throw that case up on the instant—invariably. Do you understand that? Now I must tell you that I have made no progress with your case, none; for that very reason.'"
"He protested, of course—vowed he had told me the simple truth, and so forth. I replied by asking him certain definite questions. First, I asked him whose the diamonds were. He repeated that they were his own. To that I simply replied, 'Good evening, Mr. Samuel,' and turned away. He came after me beseechingly, and prevaricated. He said something about another party having an interest, but the matter being confidential. To that I responded by asking him with whom he had communicated before sending for me, and who was the person in the brougham which he had twice entered. That flabbergasted him. He said that he couldn't answer those questions without bringing other parties into the matter, to which I answered that it was just those other parties that I meant to know about, if I were to move a step in the matter. At this he got into a sad state—imploring, actually imploring, me not to desert him. He said he should do something desperate—something terrible—that night if I didn't relieve his mind, and undertake the case. What he meant he'd do I didn't know, of course, but it didn't move me. I said finally that I would deal only with principals, and that until I had the personal instructions of the actual owner of the diamonds, in addition to a complete explanation of the brougham incident, I should do nothing, and I recommended him to go to the police; and with that I left him."
"And you got nothing more from him than that?"
"Nothing more; but it was something, you see. He admitted, to all intents, that the diamonds were not his own. And now see here. I suppose I left him about ten o'clock. Here is a paragraph in one of this morning's newspapers. It is only in the one paper; the matter seems to have occurred rather late for press."
Hewitt gave me the paper in his hand, pointing to the following paragraph:
"Horrible Discovery.—A shocking discovery was made just before midnight last night, near the York column, where a police-constable found the dead body of a man lying on the stone steps. The body, which was fully clothed in the ordinary dress of a labouring man, bore plain marks of strangulation, and it was evident that a brutal murder had been committed. A singular circumstance was the presence of a curious reddish mark upon the forehead, at first taken for a wound, but soon discovered to be a mark apparently drawn or impressed on the skin. At the time of going to press, no arrest had been made, and so far the affair appears a mystery."
"Well," I said, "this certainly seems curious, especially in the matter of the mark on the forehead. But what has it all to do——"
"To do with Samuel and his diamonds, you mean? I'll tell you. That dead man is Denson!"
"Denson?" I exclaimed. "Denson? How?"
