"What, then, seems more likely?" I asked, hotly. "Would the murderer have gone to all that trouble to get the stone, and then have left it behind?"
"Possibly, Mr. Morgan, to have been recovered at leisure—as you, indeed, happened to recover it. Such a jewel would not be a good thing to have in one's possession, immediately after the murder."
"But the operation of hiding the stone in the soap would have taken fifteen or twenty minutes at least," I objected, "and we burst in the door within less than ten minutes from the time Mr. Ashton's cry was heard."
"The alarm was given by you, Mr. Morgan. You alone heard Mr. Ashton's cry. Whether you heard it at six o'clock, or five, or four, rests upon your word alone. We do not accuse you, remember, we are trying to arrive at the truth. We do not imply that you hid the jewel any more than we imply that Miss Temple did so herself, and left her handkerchief behind as a mute witness of the fact. We do know that somebody did so, and the facts we have just stated, coupled with Miss Temple's refusal to explain her early expedition from the house that morning, all point to something we do not yet understand. With Miss Temple and yourself working together, much seems explainable that before seemed dark and mysterious. Even the closing of the window from within the green room may be explained, upon this hypothesis, for you had ample time to close it while Major Temple was examining Mr. Ashton's belongings in his frenzied search for the lost emerald. We are convinced of one thing: that the Chinaman did not commit the murder, for, had he done so, he would have taken the stone along with him, since that was the sole purpose he had in view."
"I do not agree with you there," I said. "Mr. Ashton may have hidden the jewel himself, and then the Chinaman, after committing the murder, may have been unable to find it. That would account for Li Min's subsequent search of the room, and his confederates' actions when they began to suspect, as Li Min no doubt did when he saw me remove the cake of soap, that the emerald was hidden within it."
"You are right in what you say, Mr. Morgan, if Mr. Ashton hid the jewel himself. But the subsequent actions of Li Min and his confederates are equally explainable upon the theory that they had nothing to do with the murder whatever, and were merely attempting to steal the jewel at the first opportunity."
I made no reply. They seemed to be weaving a net of circumstantial evidence about me that, try as I would, I did not seem able to break through.
"We have alluded," continued the Inspector, "to your sympathy with Miss Temple, to the use of her handkerchief to hold the bits of soap, to the fact that you alone heard Mr. Ashton's cry and alarmed the house, to your presence in the murdered man's room at a time when you could readily have bolted the window from within, to your strange failure to mention the matter of the cake of soap to Sergeant McQuade, and to the fact that the jewel was found in your possession. We now come to another curious fact, which we trust you may be able to explain satisfactorily. The weapon with which this murder was apparently committed was found this morning, locked in a drawer in the room you occupied at Major Temple's house. It was wrapped in a handkerchief marked with your initials. Can you tell us how it came to be there?"
I turned to the Inspector with a bitter laugh. "I can tell you," I replied, "but, I presume, you will not believe me. I put the weapon, which was a brass-headed poker, there myself. I found it on the lawn outside of Mr. Ashton's window, the day before yesterday."
"Why did you also conceal this important piece of evidence from Sergeant McQuade?" demanded the Inspector in a stern voice.
