detective's face wore a puzzled expression. "I've been round every flower-bed outside the windows," he said to the police inspector, "and not a trace of a footprint can I find. And yet we know that Murbridge was away from the inn at a late hour, and there's evidence enough upstairs to show that somebody made his way into Mr. Standerton's room between midnight and daybreak. Later I'll go down to the village and make a few enquiries there. It's just possible somebody may have met the man upon the road." He was as good as his word, and when he returned to the Manor House at a late hour he knew as much about Richard Murbridge's movements on the preceding evening as did any man in the neighbourhood. Jim dined alone that night, though it would be almost a sarcasm to dignify his meal with such a name. He had spent the afternoon going through his father's papers, in the hope of being able to discover some clue that might ultimately enable him to solve the mystery concerning Murbridge.

He was in the act of closing the drawer, when there came a tap at the door, and Wilkins entered to inform him that the detective had returned and was at his service, should he desire to see him. "Show him in, Wilkins," said James, locking the drawer of the table, and placing the key in his pocket as he spoke. The butler disappeared, to return a few moments later accompanied by the individual in question. "Well, Mr. Robins," said Jim, when they were alone together, "what have you discovered?" "Nothing of very much importance, sir, I am afraid," the other replied. "I have found out that Murbridge left the park by the main gates almost on the stroke of half-past eight last night. I have also discovered that he was again seen within a few minutes of eleven o'clock, standing near the small stile at the further end of
