Slowly the Belgian prepared for bed. If he were being watched, he could not know; but if so the watcher saw no indication of the nervous excitement which the European strove to conceal. When ready for his blankets, the man crossed to the little table and extinguished the light.

It was two hours later that the flaps at the front of the tent separated silently and gave entrance to a dark-robed figure, which passed noiselessly from the darkness without to the darkness within. Cautiously the prowler crossed the interior. In one hand was a long knife. He came at last to the pile of blankets spread upon several rugs close to one of the tent walls.

Lightly, his fingers sought and found the bulk beneath the blankets — the bulk that should be Albert Werper. They traced out the figure of a man, and then an arm shot upward, poised for an instant and descended. Again and again it rose and fell, and each time the long blade of the knife buried itself in the thing beneath the blankets. But there was an initial lifelessness in the silent bulk that gave the assassin momentary wonder.
