It was much against the grain for Ronicky Doone to attack a man by surprise, but necessity is a stern ruler. And the necessity which made him strike made him hit with the speed of a snapping whiplash and the weight of a sledge hammer. Before the other was fully turned that iron-hard set of knuckles crashed against the base of his jaw.
He fell without a murmur, without a struggle, Ronicky catching him in his arms to break the weight of the fall. It was a complete knock-out. The dull eyes, which looked up from the floor, saw nothing. The square, rather brutal, face was relaxed as if in sleep, but here was the type of man who would recuperate with great speed.
Ronicky set about the obvious task which lay before him, as fast as he could. In the man's coat pocket he found a handkerchief which, hard knotted, would serve as a gag. The window curtain was drawn with a stout, thick cord. Ronicky slashed off a convenient length of it and secured the hands and feet of his victim, before he turned the fellow on his face.
Next he went through the pockets of the unconscious man who was only now beginning to stir slightly, as life returned after that stunning blow.
It was beginning to come to Ronicky that there was a strange relation between the men of this house. Here were three who apparently started out to work at night, and yet they were certainly not at all the type of night clerks or night-shift engineers or mechanics. He turned over the hand of the man he had struck down. The palm was as soft as his own.
No, certainly not a laborer. But they were all employed by "the old man." Who was he? And was there some relation between all of these and the man who sneered?
At least Ronicky determined to learn all that could be read in the pockets of his victim. There was only one thing. That was a stub-nosed, heavy automatic.
It was enough to make Ronicky Doone sigh with relief. At least he had not struck some peaceful, law-abiding fellow. Any man might carry a gun--Ronicky himself would have been uncomfortable without some sort of weapon about him but there are guns and guns. This big, ugly automatic seemed specially designed to kill swiftly and surely.
He was considering these deductions when a tap came on the door. Ronicky groaned. Had they come already to find out what kept the senseless victim so long?
