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 Sergeant looked distinctly disappointed. He stepped to the corner of the roof, made a further examination of the vines, came back to the window and again tried to open it, then, with a low whistle, he pointed to a mark upon the white window sill which had at first escaped both his and my attention. It was the faint print of a hand – a bloody hand – small and delicate in structure, yet, mysterious as seemed to be all the clues in this weird case, it pointed, not outward from the room, as though made by someone leaving it, but inward, as by a person standing on the roof and resting his or her hand upon the window sill while attempting to open the window.
"What do you make of that, Sir?" inquired the detective.
"It looks as though it had been made by someone entering instead of leaving the room," I replied. "It could not have been made by anyone leaving the room. No one would get out of a window that way."
"Except a woman," said McQuade dryly. "A man would swing his legs over the sill and drop to the roof. It's barely three feet. But a woman would sit upon the sill, turn on her stomach, rest her hands on the sill with her fingers pointing toward the room, and slide gently down until her feet touched the roof beneath." He smiled with a quiet look of triumph.
"The whole thing is impossible," I retorted, with some heat. "There's no sense in talking about how anyone may or may not have got out of the room, when the bolted window proves that no one got either in or out at all."
"Perhaps you think that poor devil in there killed himself," said the detective, grimly. "Somebody must have got in. There is only one explanation possible. The window was bolted after the murder."
"By the murdered man, I suppose," I retorted ironically, nettled by his previous remark.
"Not necessarily," he replied coldly, "but possibly by someone who desired to shield the murderer." He looked at me squarely, but I was able to meet his gaze without any misgivings. "I was the first person who entered the room," I said, earnestly, "and I am prepared to make oath that the window was bolted when I entered."
"Was the room dark?" he inquired.
"It was," I answered, not perceiving the drift of his remarks. "One of the servants brought a candle."
"Did you examine the windows at once?"
"No."
"What did you do?"
"I knelt down and examined the body."
"What was Major Temple doing?"
"I – I did not notice. I think he began to examine the things in Mr. Ashton's portmanteau."
"Then, Mr. Morgan, if, occupied as you were in the most natural duty of determining whether or not you could render any aid to Mr. Ashton, you did not notice Major Temple's movements, I fail to see how you are in a position to swear to anything regarding the condition of the window at the time you entered the room."
"Your suggestion is impossible, Sergeant McQuade. Had Major Temple bolted the window, I should certainly have noticed it. I realize fully the train of reasoning you are following and I am convinced that you are wrong."
The Sergeant smiled slightly. "I do not follow any one train of reasoning," he retorted, "nor do I intend to neglect any one. I want the truth, and I intend to have it." He left the roof hurriedly, and, entering the house we descended to the library, where Major Temple sat awaiting the conclusion of our investigations.
"Well, Mr. Morgan," he inquired excitedly as we came in, "what have you discovered?"
I nodded toward the Sergeant. "Mr. McQuade can perhaps tell you," I replied.
"I can tell you more, Major Temple," said the detective, gravely, "if you will first let me have a few words with Miss Temple."
"With my daughter?" exclaimed the Major, evidently much surprised.
"Yes," answered the detective, with gravity.
"I'll go and get her," said the Major, rising excitedly.
"If you do not mind, Major Temple, I should much prefer to have you send one of the servants for her. I have a particular reason for desiring you to remain here."
I thought at first that Major Temple was going to resent this, but, although he flushed hotly, he evidently thought better of it, for he strode to a call bell and pressed it, then, facing the detective, exclaimed:
"I think you would do better to question Li Min."
"I do not intend to omit doing that, as well," replied McQuade, imperturbably.
We remained in uneasy silence until the maid, who had answered the bell, returned with Miss Temple, who, dismissing her at the door, faced us with a look upon her face of unfeigned surprise. She appeared pale and greatly agitated. I felt that she had not slept, and the dark circles under her eyes confirmed my belief. She looked about, saw our grave faces, then turned to her father. "You sent for me, Father?" she inquired, nervously.
"Sergeant McQuade here" – he indicated the detective whom Miss Temple recognized by a slight
