“That's most remarkable, sir,” said Donald, genuinely puzzled. “I never would have suspected Charley of that. He has brains enough to know the consequences of murder. I can't understand it.”

“Neither can Cardepie, evidently. He says he knows no reason for the deed.” Fitzpatrick heaved himself up, and leaned forward interestedly. “You know,” he went on, “that this thing cannot go unpunished. Charley Seguis must be captured, and brought to the fort here.”

“Will the mounted police get here before—?” began McTavish.

“The mounted police be hanged! There are only seven hundred of them, and they have to cover a country as big as Siberia. You don't suppose I'm going to wait for them, do you? Nominally, they're the law here, but literally I and the men under me are. Retribution in this case must be swift and sure, as it always has been from Fort Severn.” Fitzpatrick paused to breathe.

“Then, you mean that I must go out and get him,” Donald interpreted, calmly.

“You spare me the trouble of saying it,” replied the other. “When can you start?”

“In three hours.”

Fitzpatrick glanced at the clock on the wall.

“Too late now,” he said. “Better wait until to-morrow. The feed and the night's rest will do you good. Whatever happens, you've got to be faster than that half-breed.” He paused a minute. “If you go at dawn, I probably won't see you again. In that case, let me remind you, McTavish, of the matter of which we were speaking before this murder came up. I—”

“You don't need to remind me. I remember it perfectly.” Donald moved toward the door.
