Chester stirred in his sleep and the man shrank back against the wall in the darkness. For perhaps five minutes he remained there, and then, as there was no further move by the sleeper, he advanced into the center of the room. The light fell upon his face, and had the boys been awake, they would have recognized in the intruder, Matin, the man who had attempted to shoot Hal a short time before.

Matin approached the two sleepers quietly, seeking to make sure which was Hal. He examined each closely and then grinned as he stepped back a pace or two, apparently satisfied.

From the next room there came the sound of footsteps and again Matin shrank back against the wall. Directly the footsteps moved away and Matin drew a breath of relief.

From his pocket now he produced a knife, examined it carefully and grinned again. Looking carefully about to make sure that there was no one in the room to observe him, he stepped forward.

Had he turned his head at that moment he would have seen a second figure lowering itself just inside the room. But so intent was Matin upon the dark deed ahead of him that, after his one observation of the room, he did not look again.

The second figure was creeping after Matin now. He was not far behind, but still he was not close enough to touch the first intruder. Matin took two quick steps forward and raised his arm. Then he bent on one knee.

The arm flashed down!

But the knife never reached its mark.
