"Is there any reason to suppose," inquired McQuade, "that its presence here indicates that the room has been entered by Li Min or any of his countrymen, in an attempt to recover the emerald which I understand Mr. Ashton had with him? Might it not equally well have belonged to the dead man himself—a copy, perhaps, made by him of the character—a curiosity in other words, which he might have desired to preserve?" I followed his line of reasoning. I had told him nothing of the relations between Miss Temple and Ashton, but it was evident that the finding of her handkerchief in the murdered man's room had started him off on another tack. "None whatever," the Major responded. "Yet since the jewel has disappeared, its recovery was in my opinion beyond question the reason for the murder, and but four[55] persons knew of the presence of the jewel in this house." [55] "And they were—?" The detective paused. "My daughter, Mr. Morgan, Li Min, and myself." "How did Li Min come to know of it?" "He saw us examining it at dinner last night, while waiting on the table." The detective pondered. "Was the stone of such value that its recovery would have been sought at so great a cost?" He glanced gravely at the silent figure upon the floor. "Intrinsically it was worth perhaps a hundred thousand pounds—as a curio, or as an object of religious veneration among the Buddhist priests and their followers, it was priceless." Major Temple spoke with the fervor and enthusiasm of the collector. Sergeant McQuade's eyes widened at this statement. "A hundred thousand pounds!" he exclaimed. "And you intended to buy it from Mr. Ashton?"[56] [56] The Major hesitated. "Yes," he stammered, "yes, I did." "At what price?" came the question, cold and incisive. "I—I—Mr. Ashton secured the jewel for me as my agent."
