A strip of lattice-work ran up the side of the entrance. Very carefully, testing every slat with his weight before trusting himself to it, he climbed up and edged forward noiselessly upon the roof. On hands and knees he crawled to the window and tried to peer in.

The blind was down, but he could see that the room was dark. What danger lurked behind the drawn blind he could not guess, but after a moment, to make sure that the revolver beneath his belt was ready for instant use, he put his hand gently on the sash.

His motions were soundless as the fall of snowflakes. The window moved slowly, almost imperceptibly, under the pressure of his hands. It gave not the faintest creak of warning. His fingers found the old-fashioned roller blind and traveled down it to the bottom. With the faintest of clicks he released the spring and guided the blind upward.

Warily he lifted one leg into the room. His head followed, then the rest of his body. He waited, every nerve tensed.

There came to him a sound that sent cold finger-tips laying a tattoo up and down his spine. It was the intake of some one's cautious breathing.

His hand crept to the butt of the revolver. He crouched, poised for either attack or retreat.

A bath of light flooded the room and swallowed the darkness. Instantly
Clay's revolver leaped to the air.
