particles of some green substances, some very small, others of considerable size. I did not at first realize what they were.
"Do you see anything?" asked the Inspector.
"Yes," I replied. "The handkerchief is full of fine green specks, but I cannot imagine what they are."
"They are bits of soap, Mr. Morgan," said the detective, as he folded up the handkerchief and replaced it in his wallet.
"Soap," I cried, more than ever mystified.
"Exactly!" The Inspector looked at me keenly. "Has it not occurred to you, Mr. Morgan, that in order to place the jewel inside the cake of soap, it was first necessary to cut it in two, and hollow out a space in the interior? Is it not also quite evident that anyone so hiding the jewel would perform this operation very carefully, so as to leave behind no traces, and that the bits of soap removed from the interior of the cake must have been carefully collected upon some object, this handkerchief, for instance, and subsequently thrown away, leaving the minute particles that you see still clinging to its surface?"
"Yes," I replied, dazed. "But who?"
"That, Mr. Morgan, is just what we are trying to find out. It hardly seems likely that Mr. Ashton would have gone to all this trouble, although it is possible, since he had reason, after his quarrel with Major Temple, to fear an attempt to gain possession of the jewel. If he did, how does it happen that he used Miss Temple's handkerchief for the purpose? He may of course have found it upon the floor and so utilized it, but it seems unlikely."
"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.
I felt like a fool, and looked like one, as well, I fear. "I forgot it," I mumbled in confusion.
"You forgot it!" The Inspector believed that I was lying, and showed it. "Can you expect a sane man to believe any such folly as that?"
"Folly, or not," I replied, "it is the truth. I found the poker the day before yesterday, late in the afternoon. I intended to show it privately to Sergeant McQuade. He was in Exeter at the time and I placed it in the drawer for safe keeping. When he returned that evening, it was just in time to listen to Major Temple's story of his experiences in China, and, when he had finished, it was close to midnight and the matter had completely slipped my mind. The inquest the following morning took my entire attention and, after that, the sudden arrest of Li Min, and our departure for London. You know what has occurred since. I had forgotten the matter completely until I received this telegram from Miss Temple not half an hour before you came." I took the dispatch from the table and handed it to the Inspector, who read it with interest.
"Why did Miss Temple send you this?" he inquired suddenly.
"I do not know—I suppose she thought it would be of interest to me."
"Did it not occur to you that it might be in the nature of a warning?"
Again I saw a chasm yawning before me. Every step in this miserable affair seemed to make matters look blacker and more sinister as far as I was concerned.
"Miss Temple has no reason to suspect me of any part in the matter," I replied. "Do you think it at all likely that, if I had committed the murder, I could have left such damning evidence as the weapon where the police would have been certain to discover it, and wrapped in my own handkerchief, to render my detection the easier? What is your theory of the crime, Inspector Burns, upon the present evidence? Reconstruct the events of that night as you think they might have occurred. I will not take it to heart if you do me any injustice, for I am as innocent of any complicity in Mr. Ashton's murder as you are."
The Inspector seemed impressed by my words and manner. He looked at Sergeant McQuade, who nodded slightly. Then he transferred his gaze to me. "I have no objection, Mr. Morgan, to outlining a theory of the murder which seems to me to fit the facts as we know them. It may or may not be correct, but it is my plan to work out whatever theory will most nearly fit all the facts in my possession, and then test it from every standpoint until it either fails, or is proven true. I shall be obliged to you if you will indicate, when I have finished, any points which seem to you not to coincide with such evidence as we now have before us.
"Miss Temple," began the Inspector, "knew that Ashton had her letter in which she agreed to marry him
