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[41] 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[42] 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[43] 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
