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."

He shook his head slowly. "What a pity!" he remarked. "What a pity! If the stone is ever found now, the authorities will hold it as the property of the dead man or his relations, if indeed he has any. And it would have been the crowning glory of my collection." It was evident that Major Temple was far more concerned over the loss of the emerald than over the death of Robert Ashton. "But they will never find it—never!" he concluded with a cunning smile, and an assurance that startled me. I wondered for a moment whether Major Temple knew more about the mysterious death of Robert Ashton than appeared upon the surface, but, recollecting his excited search of the dead man's belongings, dismissed the idea as absurd. It recurred, however, from time to time during my short drive to Exeter, and the thought came to me that if Major Temple could in any way have caused or been cognizant of the death of Robert Ashton from without the room—without entering it—his first act after doing so would naturally have been to search for the emerald in the hope of securing it before the police had been summoned to take charge of the case. I regretted that I had not examined the floor of the attic above, to determine whether any carefully fitted trap door, or hidden chimney or other opening to the interior of the room below existed. I also felt that it was imperative that a careful examination of the walls, as well as of the ground outside beneath the three windows, should be made without delay. It was even possible, I conjectured, that a clever thief could have in some way cut out one of the window panes, making an opening through which the window might have been opened and subsequently rebolted, though just how the glass could then have been replaced was a problem I was not prepared to solve. There was no question, however, that Robert Ashton was dead, and that whoever had inflicted that deadly wound upon his head, and made away with the emerald Buddha, must have entered the room in some way. I was not yet prepared to base any hypotheses upon the supernatural. As I concluded these reflections, we entered the town by way of Sidwell street and I stopped at the Half Moon and secured my luggage. We then drove to the police headquarters and I explained the case hurriedly to the Chief Constable, omitting all details except those pertaining directly to Mr. Ashton's death. The Chief Constable sent one of his men into an inner room, who returned in a moment with a small, keen-looking, ferret-faced man of some forty-eight or fifty years of age, with gray hair, sharp gray eyes and a smooth-shaven face. He introduced him to me as Sergeant McQuade, of Scotland Yard, who it seemed, happened to be in the city upon some counterfeiting case or other, and suggested that he accompany me back to the house. We had driven in Major Temple's high Irish cart, and, putting the man behind, I took the reins and with Sergeant McQuade beside me, started back in the direction of The Oaks. We had scarcely left the limits of the town behind us, when I noticed a figure in blue plodding slowly along the muddy road ahead of us, in the same direction as ourselves, and Jones, the groom upon the drag behind me said, in a low voice as we drew alongside, that it was Li Min, Major Temple's Chinese servant, whose sudden disappearance earlier in the morning had caused so much excitement. The Chinaman looked at us with a blandly innocent face and, nodding pleasantly, bade us good morning. I stopped the cart and ordered Jones to get down and accompany him back to the house, and on no account to let him out of his sight. As we drove on I explained all the circumstances of the case in detail to Sergeant McQuade, and informed him of my reason for placing Jones as guard over the Chinaman. No sooner had I done so than the Sergeant, in some excitement, requested me to return with him to Exeter at once. I did not inquire into his reasons for this step, but turned my horse's head once more toward the town, the Sergeant meanwhile plying me with questions, many of which I regretted my inability to answer to his satisfaction. They related principally to the exact time at which the murder had occurred, and how soon the disappearance of Li Min had been discovered. I decided at once that the detective had concluded that Li Min had committed the murder and had then hurried off to Exeter to place the emerald Buddha in the hands of some of his countrymen in the town, and was now proceeding leisurely back with some plausible story and a carefully arranged alibi to explain his absence from the house. I mentioned my conclusions to the Sergeant and saw from his reply that my assumption was correct. "I hope we are not too late," he exclaimed as he suggested my urging the horse to greater speed. "It is absolutely necessary that we prevent any Chinaman from leaving the town until this matter is cleared up. I'm afraid however, that they have a good start of us. There is a train to London at eight, and, if our man got away on that, it will be no easy matter to reach him."

"Of course you can telegraph ahead," I ventured.

"Of course." The detective smiled. "But the train is not an express, and there are a dozen stations within fifty miles of here where anyone could leave the train before I can get word along the line." He looked at his watch. "It is now ten minutes of nine. I am sorry that you did not notify the police at once." I made no reply, not wishing to prejudice the detective against Major Temple by explaining my desire to do this very thing and the latter's disinclination to have it done. We had reached police headquarters by this time, and the Sergeant disappeared within for perhaps five minutes, then quickly rejoined me and directed me to drive to the Queen Street Station. I waited here for him quite a long time and at last he came back with a face expressive of much dissatisfaction. "Two of them went
