"Infernal impudence!" said a bystander; "wanted to come and take a quiet look at his work, I reckon--didn't expect any company."

The crowd fell apart, now, and the Sheriff came through, ostentatiously leading Potter by the arm. The poor fellow's face was haggard, and his eyes showed the fear that was upon him. When he stood before the murdered man, he shook as with a palsy, and he put his face in his hands and burst into tears.

"I didn't do it, friends," he sobbed; "'pon my word and honor I never done it."

"Who's accused you?" shouted a voice.

This shot seemed to carry home. Potter lifted his face and looked around him with a pathetic hopelessness in his eyes. He saw Injun Joe, and exclaimed:

"Oh, Injun Joe, you promised me you'd never--"

"Is that your knife?" and it was thrust before him by the Sheriff.

Potter would have fallen if they had not caught him and eased him to the ground. Then he said:

"Something told me 't if I didn't come back and get--" He shuddered; then waved his nerveless hand with a vanquished gesture and said, "Tell 'em, Joe, tell 'em--it ain't any use any more."

Then Huckleberry and Tom stood dumb and staring, and heard the stony-hearted liar reel off his serene statement, they expecting every moment that the clear sky would deliver God's lightnings upon his head, and wondering to see how long the stroke was delayed. And when he had finished and still stood alive and whole, their wavering impulse to break their oath and save the poor betrayed prisoner's life faded and vanished away, for plainly this miscreant had sold himself to Satan and it would be fatal to meddle with the property of such a power as that.

"Why didn't you leave? What did you want to come here for?" somebody said.

"I couldn't help it--I couldn't help it," Potter moaned. "I wanted to run away, but I couldn't seem to come anywhere but here." And he fell to sobbing again.

Injun Joe repeated his statement, just as calmly, a few minutes afterward on the inquest, under oath; and the boys, seeing that the lightnings were still withheld, were confirmed in their belief that Joe had sold himself to the devil. He was now become, to them, the most balefully interesting object they had ever looked upon, and they could not take their fascinated eyes from his face.

They inwardly resolved to watch him nights, when opportunity should offer, in the hope of getting a glimpse of his dread master.
