"Even the cleverest criminals in the world couldn't bolt a door or window from the outside," I said.
"Do not be too sure of that. I have known them to do things equally strange. By inserting a thin steel wedge between the edge of the door and the jamb they might with infinite patience work the bolt to one side or the other. This fellow, Li Min, I brought from China with me. He is one of the most faithful servants I have ever known. He belongs to the higher orders of society—I mean that he is not of the peasant or coolie class. He represented to me that he was suspected of belonging to the Reform Association, the enemies of the prevailing order of things, and was obliged to leave the country to save his head. I do not know, I do not know—possibly he may have been sent to watch. They knew in Ping Yang that I was after the emerald Buddha. Who knows? They are an amazing people—an amazing people." He turned to me suddenly. "Did you hear any footsteps or other noises in the hallway during the night?"
I told him that I thought I had, but that I could not be sure, that my sleep had been troubled, but that I had only awakened a few minutes before I heard Ashton's cry. At this moment Gibson returned, with a scared look on his face. Li Min, he reported, had disappeared. No one had seen him since the night before. His room had apparently been occupied, but the Chinaman was nowhere to be found.
"The police must be notified at once," I urged.
"I will attend to it," said the Major. "First we must have some coffee."
He closed the door of the room carefully, after we left it, and, taking the key from the lock—it had evidently not been used by Mr. Ashton the night before—locked the door from the outside and ordered Gibson to remain in the hallway without and allow no one to approach.
We finished dressing and then had a hurried cup of coffee and some muffins in the breakfast-room. It was by now nearly eight o'clock, and I suggested to Major Temple that if he wished, I would drive into Exeter with one of his men, notify the police and at the same time get my luggage.
I assured him that I had no desire to inflict myself upon him further as a guest, but that the murder of Ashton and the necessity of my appearing as a witness at the forthcoming inquest made it imperative that I should remain upon the scene until the police were satisfied to have me depart. At my mention of the police the Major showed great uneasiness, as before.
"You need not say anything about the—the emerald," he said, slowly; "it would only create unnecessary talk and trouble."
"I'm afraid I must," I replied. "It is evidently the sole motive for the murder—it has disappeared, and unless the police are apprised of its part in the case, I fail to see how they can intelligently proceed in their attempts to unravel the mystery."
