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 up on the eight train," he growled. "One of them the clerk in the booking office remembers as keeping a laundry in Frog Street. The other he had never seen. They took tickets for London, third class." He swung himself into the seat beside me and sat in silence all the way to the house, evidently thinking deeply.
When we arrived at The Oaks, very soon after, we found the Major waiting impatiently for us in the hall. Jones and Li Min had arrived, and the Major had subjected the latter, he informed us, to a severe cross-examination, with the result that the Chinaman had denied all knowledge of Mr. Ashton's death and explained his absence from the house by saying that he had gone into town the night before to see his brother who had recently arrived from China, and, knowing the habit of the household to breakfast very late, had supposed his return at nine o'clock would pass unnoticed. I made Major Temple acquainted with Sergeant McQuade, and we proceeded at once to the room where lay all that now remained of the unfortunate Robert Ashton.
Chapter 3
A QUEER DISCOVERY
We found Gibson guarding the door where we had left him. Miss Temple was nowhere to be seen. Major Temple took the key from his pocket, and, throwing open the room, allowed McQuade and myself to enter, he following us and closing the door behind him.
"Where did you get the key?" asked the detective as Major Temple joined us.
"It was in the door—on the inside."
"Had the door been locked?"
"No. It was bolted."
"And you broke it open when you entered?"
"Yes. Mr. Morgan and my man, Gibson, forced it together."
McQuade stepped to the door and examined the bolt carefully. The socket into which the bolt shot was an old-fashioned brass affair and had been fastened with two heavy screws to the door jamb. These screws had been torn from the wood by the united weight of Gibson and myself when we broke open the door. The socket, somewhat bent, with the screws still in place, was lying upon the floor some distance away. McQuade picked it up and examined it carefully, then threw it aside. He next proceeded to make a careful and minute examination of the bolt, but I judged from his expression that he discovered nothing of importance, for he turned impatiently from the door and, crossing the room, bent over the dead man and looked long and searchingly at the curious wound in his head. He then examined the fastenings of the windows minutely, and, raising one of the large windows in the south wall, looked out. Evidently nothing attracted his attention outside. He turned from the window, after closing it again, and started toward us, then stooped suddenly and picked up a small white object which lay near one of the legs of a table standing near the window. It was in plain view, and I wondered that I had not seen it during my previous examination of the room. McQuade handed the object, a small bit of lace, I thought, to Major Temple. "What do you make of that?" he asked.
Major Temple took the thing and spread it out, and I at once saw that it was a woman's handkerchief. My surprise at this was overbalanced by the look of horror which spread over the Major's face. He became deathly pale, and his hand shook violently as he looked at the bit of lace before him. I stepped to his side and saw, as did he, the initials, M. T., in one corner and noticed a strong and most peculiar odor of perfume, some curious Oriental scent that rose from the handkerchief. McQuade gazed at us, curiously intent. "Do you recognize it?" he inquired.
"Yes," said Major Temple, recovering himself with an effort. "It is my daughter's."
"How do you explain its presence here?" asked the detective.
"I do not attempt to do so, any more than I can undertake to explain any of the other strange events connected with this horrible affair," said the Major, pathetically. He seemed to me to have aged perceptibly since the evening before; he looked broken, old.
McQuade took the handkerchief and placed it carefully in his pocket, and continued his examination of the room. As he did so, I stood aside, a prey to strange thoughts. I felt ready to swear that the handkerchief had not been upon the floor during my previous examination of the room, yet how could its presence there now be explained, with the door locked, the key in Major Temple's pocket, and Gibson on guard in the hall. I thought of Muriel Temple, young, beautiful, innocent in every outward appearance, yet remembered with a qualm of misgiving her flashing eyes and determined manner as she spoke of Robert Ashton, her aversion to him, and her determination never to marry him under any circumstances. I felt that there was more beneath this strange tragedy than had yet appeared upon the surface, yet, believing thoroughly in the innocence of Miss Temple of any part in the affair, I mentally resolved to do all in my power to sift it to the bottom. I had no illusions as to any special skill upon my part as an amateur detective, and I did not propose to come forth equipped with magnifying glass and tape measure and solve the problem in the usual half-hour which sufficed for the superhuman sleuth of fiction, but I felt that I did possess common sense and a reasonably acute brain, and I believed that, with sufficient time and effort, I could find out how and why Robert Ashton had come to his sudden and tragic end. My thoughts were interrupted by Sergeant McQuade, who, having brought his examination to a sudden close, announced to Major Temple that the police and the divisional surgeon would arrive shortly and that meanwhile he would have a look at the grounds beneath the windows of the room. I decided to accompany him, but, before doing so, I suggested to the Major that it might be well to show Sergeant McQuade the scrap of paper, containing the single Chinese character, which we had found upon the floor. Major Temple took it from his pocket and handed it to the detective without a word. I could see that the latter was puzzled. "What does it mean?" he inquired. "Do you know?" He turned to Major Temple.
"Only that it is a religious symbol used by the Buddhist priests in China," said the latter. "It is found in
