Standing there, the wrench in his hand, Orme felt that the advantage was his. He heard rustlings in the branches above his head and kept himself alert to guard against the man dropping on his shoulders.

To strike the Japanese down as he dropped from the tree, that was his plan. But meantime, where was the other Japanese? Was he among the near shadows? If so, he might even now be creeping stealthily toward Orme. The likelihood of such an attack was disconcerting to think of. But as Orme was wondering about it, it occurred to him that the man in the tree would not have gone on guard so quickly, if his confederate were near at hand. It was natural that he should have put the light out, but would he not immediately afterward have given some signal to the friend below? And would he not take it for granted that, were a stranger near, his watcher would have managed to give warning? No, the other Japanese could not be on guard.

Perhaps, thought Orme, only one of them had come on this quest. He hoped that this might be the case. He could deal with one.

The man in the tree was taking his own time to descend. Doubtless he would await a favorable moment, then alighting on the ground as far from Orme as possible, make off at top speed.

But now, to Orme’s surprise, a figure swung from the lower branch apparently without haste. Once on the ground, however, the stranger leaped toward Orme.

An intuition led Orme to thrust out his left arm. It was quickly seized, but before the assailant could twist it, Orme struck out with the wrench, which was in his right hand. Swift though the motion was, his opponent threw up his free arm and partly broke the force of the blow. But the wrench reached his forehead nevertheless, and with a little moan, he dropped to the ground in a heap.

As Orme knelt to search the man, another figure swung from the tree and darted northward, disappearing in the darkness. Orme did not pursue—it was useless—but a sickening intuition told him that the man who had escaped was the man who had the envelope.

He struck a match. The man on the ground was moving uneasily and moaning. There was a scar on his forehead. It was Maku.

He went through the unconscious man’s pockets. There was no envelope such as he was looking for, but he did find a folded slip of paper which he thrust into his own pocket. A discovery that interested him, though it was not now important, he made by the light of a second match. It was the marked five-dollar bill. He would have liked to take it as a souvenir, if for no other reason, but time was short and Maku, who evidently was not seriously hurt, showed signs of returning consciousness.

Another occurrence also hastened him. A man was strolling along the lake shore, not far away. Orme had not seen his approach, though he was distinctly outlined against the open background of lake and sky. The stranger stopped. The striking of the two matches had attracted his attention.
