Sitting there in the soft light of the room, he did not know whether the man on the couch was Albert Lemon or whether the man who had died in the cavern was Albert Lemon. He believed, however, that the outlaws he had encountered in the mountains, had murdered the man, and felt that the surest way to trace the crime to them was to find out why the man had joined them—why he was there in the tunnel back of the cupboard. This would be likely to bring out a motive for the deed.
He did not, of course, know whether the dead man had stood as an enemy to the outlaws, or whether he had stood as a friend. But that could make no difference with the quest he was on. He believed that the outlaws were the men he had been instructed to hunt down, and knew that proof could be obtained only by an intimate knowledge of their associations, their ways, their motives. The friends of the dead man he thought, would know something about them, perhaps be able to place them in the circle in which they lived when not in the hills.
In work of this kind it is the first task of an investigator to “place” the man he is pursuing. The burglar is as good as taken when he is traced back to those he associates with in his hours of leisure. In the absence of a clue pointing to a person, the investigator busies himself in finding a motive. Ned believed that he now had the personal clue. The motive would place the proof in his hands.
So his Secret Service work for the government was leading him into the investigation of a murder mystery. He smiled as he held up the key and wondered if the facts when discovered would bear out the suspicions in his mind. Again he asked himself the question:
“Is this Albert Lemon, or was the dead man Albert Lemon?”
After a long time the man on the couch opened his eyes and looked about the room. His glance rested for an instant on the figure in the chair at his side, but the fact of its being there did not appear to surprise him in the least.
“Jap!” he called faintly.
There was a sound at the door, but it was still locked, and the servant was unable to obey the summons.
“Bring me a pipe!” were the next words.
The Jap clamored at the door, but did not gain admission. The racket seemed to disturb the man not at all.
