Hobart stood with the three witnesses beside the door, still in the dazzling light. Harley was sure that not one of the four had moved in the last half-hour, and Jimmy Grayson still held them all with his gaze. Harley suddenly saw something like a flash of light, a signal glance, as it were, pass between him and Hobart, and the next instant the voice of the candidate swelled into greater and more accusing volume. "Now you behold the guilty man!" said Jimmy Grayson. "I have shown him to you. He seems to the world full of pride and power, but he knows that justice is pursuing him, and that it will overtake him; he trembles, he cowers, he flees, but the avenging footsteps are behind him, and the sound of them rings in his frightened ears like a death-knell to his soul. A wall rises across his way. He can flee no farther; he turns back from the wall, raises his terror-stricken eyes, and there before him the hand of fate is raised; its finger points at him, and a terrible voice proclaims, 'Thou art the guilty man!" The form of Jimmy Grayson swelled and towered, his hand was raised, the long forefinger pointed directly at the four who stood in the dazzling light, and the hall resounded with the tremendous echoes of his cry, "Thou art the guilty man!" As if lifted by a common impulse, the great audience rose with an indescribable sound and faced about, following Jimmy Grayson's long, accusing finger. The man Williams threw his arm before his face, as if to protect himself, and, with a terrible cry, "Yes, I did it!" fell in a faint on the floor. They were all on the train the next day, and Harley was reading from a copy of the Grayville _Argus_ an account of Boyd's release and the ovation that the people had given him. "How did you trace the crime to Williams, Hobart?" asked Harley. "I didn't trace it; it was Jimmy Grayson who brought it out by giving him 'the third degree,'" replied Hobart, though there was a quiet tone of satisfied pride in his voice. "You know that in New York, when they expose a man at Police Headquarters to some such supreme test, they call it giving him 'the third degree,' and that's what we did here. It seems that Williams was in the saloon when Boyd and his partner quarrelled, and he knew they had a lot of gold from the claim in their cabin. His object was robbery. When he saw Wofford go on ahead, he followed him quickly to the cabin, and killed him with the knife which lay on a table. He expected to have time to get the gold before Boyd came, but Boyd arrived so soon that he was barely able to slip out. Then Williams, cunning and bold enough, came back as if he were a chance passer-by, and had been called by Metzger and Thorpe. The other two were as innocent as you or I.
