The next instant Warner struck the door such a blow with his doubled fist that the jarring sound silenced the roar of rage that had burst from Wildresse at Philippa's answer, and checked the heavy scuffle of his great feet, too.

Already Warner had drawn back, pistol lifted, gathered together to throw his full weight against the door and hold it the moment it was opened from inside.

The sudden stillness which followed his blow lasted but a few seconds; heavy steps approached the door, halted; approached irresolutely, stopped short. Then ensued another period of quiet; and Warner, listening, could hear the breathing of Wildresse on the other side of the door.

Minute after minute passed; Wildresse, still as a tiger, never stirred, and even his suppressed breathing became inaudible after a while.

Warner, pistol in hand, ready to throw himself against the door the instant it moved on the crack, bent over and placed his ear close against the paneling. After a while he detected the sound of footsteps cautiously retreating, and realized that Wildresse did not intend to open the door.

He knocked again loudly: the steps continued to recede; somewhere another door was unbolted and opened; and the stealthy, retreating footsteps continued on beyond earshot.

Again he knocked heavily with the butt of his pistol; waited, listened, then drew back and fairly hurled himself against the door. It scarcely even creaked; he might as well have attempted to push over the retaining wall of the corridor itself.

"Philippa!" he called. "Philippa!"

A low cry answered him; he heard her stir suddenly.

But as he grasped the door knob and shook it in his excitement and impatience, over his shoulder he caught a glimpse of a gross, hairless face slyly peering around the further corner of the corridor. It disappeared immediately.
