to leave her. Then I suddenly bethought myself of the strange Oriental perfume that had clung so strongly to the handkerchief which the detective had found in the green room. I turned to her once more. "Miss Temple," I said, with some hesitation, "you will pardon me, I know, but you may remember that the handkerchief which was found in Mr. Ashton's room upon the morning of the—the tragedy, and which you thought you might have dropped there, was strongly scented with a powerful Oriental perfume. May I ask what that perfume is, and where you procured it?"
"Perfume?" she ejaculated, in surprise. "Why, Mr. Morgan, I never use any—never."
"You never use any?" I stammered. "But it was upon your handkerchief. I thought that perhaps you might have gotten it during your travels in China."
"The handkerchief was mine, Mr. Morgan—that is true. But of the perfume I know absolutely nothing. Why do you ask?"
I hardly knew what reply to make. The whole affair seemed absurdly trivial; the identity of the perfume of the soap, and of the handkerchief meant nothing, pointed to nothing, and yet I could not shake off the idea that there was some intimate connection between the perfume of the handkerchief and that of the soap which would go far toward solving the mystery of Robert Ashton's death. I bade her good-by with some simple explanation of my question, and hurried out to find McQuade. I understood that he intended going in to Exeter before luncheon, getting a bite to eat there, and taking the early afternoon express for London. I found him with one of his men upon the porch roof, busily engaged in making photographs of the bloody hand print upon the window sill of the green room. He came down presently and joined me.
"Is it not a curious fact, Mr. Morgan," he remarked, as he reached the foot of the short ladder he had used to ascend to the roof, "that, although Li Min had not only the motive for the murder, namely, the securing of the emerald Buddha, but also the opportunity, inasmuch as he could readily have reached the porch roof from within the house by means of the hall window, and while the hand print which I have been photographing is small and delicate, like that of a woman, or indeed like that of Li Min himself, yet I have tested every possible human means whereby the windows and doors of that room could have been bolted after the crime was committed, and I can see no possible way in which it could have been done, unless either Major Temple or yourself did it upon entering the room, which you certainly would neither of you have any reason to do were Li Min the guilty person? In spite of many of the peculiarities of Miss Temple's conduct, in spite of Major Temple's altercation with Mr. Ashton, I have been prepared to believe all along that Li Min was on this roof at or near daybreak yesterday morning and I do not mind telling you that I have discovered certain evidence—evidence which had before escaped me, that to my mind proves it conclusively—yet how he could have entered that room, murdered Mr. Ashton, secured the jewel, climbed out of the window and shut and bolted it behind him on the inside is beyond my comprehension. It is not humanly possible—it simply cannot be." He shook his head and looked at me in a state of evident perplexity.
I felt unable to offer any suggestions of value, but I hazarded a question. "Have you searched the attic above the room?" I asked.
"Thoroughly," he replied. "The rafters have never been floored over. The lath and plaster of the ceiling are absolutely unbroken. As for the four walls, two of them are exterior walls, without openings, except the windows. One is the solid partition between the room and the hallway. The fourth is equally solid, and of brick, between the green room and a large closet adjoining it to the east, which has evidently been used as a sort of lumber room, and contains a collection of old furniture, carpets, etc., covered with dust half an inch deep. The dust-covered floor and the rusty lock both show that it has not been entered for a long time. The furniture belongs to the owners of the property, and was evidently placed there years ago when the property was offered for leasing."
"Then it would seem that we have exhausted all possible clews," I observed. I did not think it worth while to take him into my confidence regarding Li Min, or the perfumed soap; and the brass-headed poker which I had found, and which I had placed in the drawer in my room, I had for the moment completely forgotten.
"So it seems," he remarked, thoughtfully. "This is by long odds the strangest case I have ever worked on. Possibly the two Chinamen we have in London may be able to throw some light upon it."
As we rounded the corner of the house, on our way to the front door, we suddenly saw Li Min dart out of the main entrance, closely pursued by the officer to whom I had entrusted my luggage. The Chinaman carried in his hand my Gladstone bag, and was running with incredible swiftness toward the road. Before I had time to make a move, McQuade darted forward and intercepted him, knocking from his hand with lightning-like quickness a long knife which he drew from his blouse. The two of them tumbled over upon the turf, McQuade rising first with my satchel in his hand. He looked at it, and seeing my name upon it handed it to me with a grim smile. "You must have a valuable kit here, Sir," he said, "or else this fellow has taken leave of his senses." He nodded to his assistant, who promptly stepped forward and snapped a pair of handcuffs upon the sullen-looking Oriental.
"The whole outfit isn't worth five pounds," I said, laughing, and picked up the satchel. As I did so the catch came open and my small collection of flannel shirts, toilet articles, sketching materials, etc., tumbled upon the grass. McQuade joined in my laugh, and assisted me in replacing my effects. "Nothing much here, Sir," he said, but I did not fail to notice that he observed each article closely as we repacked the satchel.
We drove back to town in the high cart, with one of Major Temple's grooms at the reins beside me, and Li Min and the Sergeant upon the rear seat. After depositing the Chinaman at the jail, we took a hurried lunch at the Half Moon, and left for London on the early afternoon express, arriving at Waterloo station about dusk. I gave McQuade the address of my lodgings and studio in Tottenham Court Road, and, as he intended reporting at once at Scotland Yard, I left him with the understanding that, if anything significant developed during his examination of the two Chinamen, he would advise me and call upon me if I could assist him in any way. I realized of course that I was purely an outsider, and in no position to expect the police to take me into their confidence, but on the other hand I was not only the most important witness in the case, but my keen interest in the solution of the mystery, for the purpose of clearing the names of both Miss Temple and her father from any vestige of suspicion, was not lost upon the Sergeant, and I think he realized that I might be of considerable assistance to him should the case take some unexpected turn. He hurried off in a hansom and I followed, stopping on my way at the Vienna Café for dinner. It was past eight when I arrived at my studio, and, throwing my bag into a corner I sat down and wrote a letter to my mother at Torquay, explaining to her my change of plans, although making no mention of the reasons which caused the change. I must have been unusually tired, owing to my early rise and the varied excitements of the day, for I dozed in my chair, and was not aroused until after eleven, when I heard a loud knock at the studio door. I sprang up, somewhat confused, and, opening the door, found under it an envelope containing a note, written on plain, rather cheap paper, in a somewhat irregular but legible hand. It was from McQuade, and requested me to meet him at once at Number 30, Kingsgate Street. There was nothing else in the note, so without further delay I threw on a warm coat and soft hat, and, hurrying to the street, summoned a cab. The driver looked a bit surprised at the address, and asked me to repeat it, which I did a bit sharply, then threw myself into the rear seat and lighted a cigarette. Events were moving quickly it seemed. McQuade, I felt sure would not have sent for me at this hour of the night unless some developments of importance had occurred. I rejoiced in the hope that the examination of the two Exeter Chinamen had resulted in the discovery of both the missing jewel and the murderer, and thought with pleasure of the expedition I should make on the morrow to The Oaks and the happy tidings I should bring to Muriel. I had thought of her so continuously, since leaving there, and felt so keenly the loss of her companionship, slight as it had so far been, that I knew that hereafter all roads, for me, would lead to Exeter until the day came when I might lead her from it as my wife. It was while occupied in these dreams that I felt my cab draw up alongside the curb, just as the hour of midnight
