and is supposed to ward off evil influences."
"Is there any reason to suppose," inquired McQuade, "that its presence here indicates that the room has been entered by Li Min or any of his countrymen, in an attempt to recover the emerald which I understand Mr. Ashton had with him? Might it not equally well have belonged to the dead man himself—a copy, perhaps, made by him of the character—a curiosity in other words, which he might have desired to preserve?"
I followed his line of reasoning. I had told him nothing of the relations between Miss Temple and Ashton, but it was evident that the finding of her handkerchief in the murdered man's room had started him off on another tack.
"None whatever," the Major responded. "Yet since the jewel has disappeared, its recovery was in my opinion beyond question the reason for the murder, and but four persons knew of the presence of the jewel in this house."
"And they were—?" The detective paused.
"My daughter, Mr. Morgan, Li Min, and myself."
"How did Li Min come to know of it?"
"He saw us examining it at dinner last night, while waiting on the table."
The detective pondered. "Was the stone of such value that its recovery would have been sought at so great a cost?" He glanced gravely at the silent figure upon the floor.
"Intrinsically it was worth perhaps a hundred thousand pounds—as a curio, or as an object of religious veneration among the Buddhist priests and their followers, it was priceless." Major Temple spoke with the fervor and enthusiasm of the collector.
Sergeant McQuade's eyes widened at this statement. "A hundred thousand pounds!" he exclaimed. "And you intended to buy it from Mr. Ashton?"
The Major hesitated. "Yes," he stammered, "yes, I did."
"At what price?" came the question, cold and incisive.
"I—I—Mr. Ashton secured the jewel for me as my agent."
"But surely you were to give him some commission, some reward for his trouble. What was that reward, Major Temple?"
"I had promised him the hand of my daughter in marriage."
"And was he satisfied with that settlement?" continued the detective, ruthlessly.
"We had a slight disagreement. He—he wanted a cash payment in addition."
"Which you refused?"
"The matter had not been settled."
"And how did your daughter regard the bargain?" asked McQuade, coldly.
Major Temple drew himself up stiffly. "I fail to see the purpose of these questions," he said with some heat. "My daughter was ready to meet my wishes, Sergeant McQuade. Mr. Ashton was a gentleman and was much attached to her. They met in China."
The detective said no more, but ordered the door locked as we passed out, and put the key in his pocket. I asked his permission to accompany him in his explorations outside, to which he readily consented, and, with a parting injunction to Major Temple to see that Li Min was not allowed to leave the house, we passed out into the gardens by a rear entrance.
The storm of the night before had completely passed away and the morning was crisp and clear, with a suggestion of frost in the air. The wind, which had not yet died down, had done much to dry up the rain, but the gravel walks were still somewhat soft and muddy. The rain however had stopped some time during the night, and as the tragedy had occurred later, and not long before daybreak, there was every reason to believe that traces of anyone approaching the house beneath the windows of Mr. Ashton's room would be clearly visible. It was equally certain that any traces of steps made before or during the rain must have been thereby completely obliterated. The soft graveled path encircled the rear of the house and turned to the front at the end of each wing. We walked along it and presently found ourselves beneath the two windows upon the south wall, which opened from the green room. There were no evidences of anyone having walked upon the pathway since the rain, nor was it apparent that anyone could have gained access to the windows high above without the aid of a ladder, which, had one been used, must inevitably have left its telltale marks behind. Sergeant McQuade looked down, then up, grunted to himself and passed on. There was nothing of interest here. At the end of the pathway we came to the termination of the wing and I saw the detective look about keenly. Here certainly the conditions were more favorable. A covered porch encircled the end of the building and extended along its front. There were three windows in the west face of the wing, one in the room which I had occupied, one in the end of the hallway and one in Mr. Ashton's room. The roof of the porch was directly beneath them. How easy, I thought at once, for anyone inside the house to have reached the porch roof from the window at the end of the hall, and to have gained, in half a dozen steps, the window of Mr. Ashton's room. I thought of the handkerchief, of the footsteps I fancied I had heard during the night, and shuddered. Here again the Sergeant first examined the graveled walk with elaborate care, but, as before, with no immediate results. Presently, however, he stepped toward the front of the house. There, in the soft gravel, were the prints of a woman's feet, leading from the corner of the path to the front entrance. I bent down and examined them with curious eyes, then recoiled with a cry of dismay. The footprints lead in one direction only, and that was toward the front door. In a flash I realized what theory McQuade would at once construct in his mind. The murderer, reaching the porch roof from the hallway, and obtaining access to the murdered man's room through the window, upon escaping from the room to the roof, would be unable to again enter the house from the roof because of my presence in the hall. What more natural than to descend from the porch to the ground by means of the heavy vines growing about the stone pillar supporting the porch roof at the corner, and, after walking quickly along the path a few steps, reach and re-enter the house through the front door, and appear almost at once among the others who had gathered in the upper hall as soon as the tragedy was known? I remembered at once that Miss Temple had appeared in a loose dressing gown. Would she, then, have had time to throw off her dress so quickly, wet and muddy as it must have been, and to change her shoes for slippers? Where were these shoes, I wondered, if this train of reasoning was correct, and would their condition prove that she had been out of the house during the night? As these thoughts crowded tumultuously through my brain, I saw McQuade examining the heavy mass of ivy which grew at the corner of the porch with a puzzled expression. Following his glance, I realized that the theory had at least a temporary setback. The vine was not broken or torn in any way as would inevitably have been the case had anyone used it as a means of descent from the roof. But I myself observed, though I felt sure that McQuade did not, a lightning rod which extended from the roof of the wing, down to the porch roof, across it, and thence to the ground about midway along the west side of the porch, and, had anyone descended in this way, he would have walked along the border between the side of the porch and the path until he arrived at the corner. Here, however, he would have been obliged to step off the border and on to the gravel, owing to the heavy vine, mentioned above, growing at this point. His footsteps upon the grass would of course have left no mark. I did not call McQuade's attention to this at the time, but waited for his next move. It did not surprise me. He strode along the path at the front of the house to the steps leading to the large porch and porte-cochère at the front of the main building, tracing the muddy footprints up to the porch and upon its floor until they were no longer perceptible. He then entered the house and at once made for the upper hall in the west wing, I following him closely. His first move, as I expected, was to examine and open the window at the end of the hall, which, I was not surprised to find, was unfastened. His second was to step out upon the roof. No sooner had I joined him here than he crossed to the window of the green room and peered in. The interior of the room was clearly visible, but the window was tightly bolted within, and resisted all his efforts to open it. The
