Gray caught at his automatic which he always hung at his pillow. He missed it in the dark. One of the figures stumbled against the bed. He felt a hand brush across his face.
Drawing up his legs swiftly he kicked out at the man who was fumbling for him. The fellow subsided backward with a grunt, and the officer gained his feet. His sight was not yet cleared, but he perceived the blur of figures in the light from the open door.
He wasted no time in outcry. Experience had taught him that the best way to deal with native assailants was with his fists. He bent forward from the hips, balanced himself and jabbed at the first man who ran up to him.
His fist landed in the intruder's face. Gray weighed over a hundred and seventy pounds, and he had the knack which comparatively few men possess of putting his weight behind his fists. Moreover, he was not easily flurried, and this coolness gave his blows added sting.
At least four men had broken into the room. The other two hesitated when they saw their companions knocked down. But Gray did not. There was a brief rustle of feet over the floor, the sound of a heavy fist striking against flesh, and the invaders stumbled or crawled from the room.
Gray was surprised they did not use their knives. Once they perceived that he was fully awake they seemed to lose heart. The fight had taken only a minute, and Gray was master of the field.
He had counted four men as they ran out. But he waited alertly by the door while Delabar, who had remained on his bed, got up and lit the lamp. Gray's first glance told him that no Chinamen were to be seen.
He was breathing heavily, but quite unhurt. Having the advantage of both weight and hitting power over his light adversaries, he took no pride in his prompt clearing of the room. Delabar, however, was plainly shaky.
"What did they want?" the professor muttered, eyeing the door. "How——"
"Look out!" warned Gray crisply.
