Jean had been right. This was more important, vastly more important, than the pursuit of a renegade half-breed... But that half-breed was himself at the head of the organization.

“That's what half an intelligence will do for a man!” said McTavish to himself, with contempt. “This fellow is just bright enough to be better than his class. He therefore immediately sets himself up as a leader to buck the Company. God help him!”

But the captain's thoughts almost immediately turned to his own case. What was that old Indian saying? He listened.

“In the past history of the Company, when a rival appeared, there had been much killing. Murder, violence, Intrigue, conspiracy—all these have flourished when a rival took the field. We may look for them now, and he who strikes first forestalls the other. It is, of course, impossible for this Captain McTavish to reach Fort Dickey or Fort Severn again. Three sentences from him, and we are discovered, and the chase begun. We are not strong enough yet for open conflict. By spring, perhaps, but not now. McTavish must never tell. A strong arm, a well-directed blow—”

“But, my good brother, you do not counsel murder in cold blood?” asked Seguis, in a tone of horror. “To kill our old friend, Captain McTavish, because he has happened to come upon us here—oh, no, no, no! It is impossible. But, yet,” he added, “he must not tell what he has seen.”

He turned to McTavish.

“Will you give an oath never to reveal what you have seen and heard here?”

“No,” Donald said bluntly. “I won't.”

“By refusal, you sign your own death-warrant,” warned the half-breed, not unkindly. “For the sake of all of us, give this oath.”

“Seguis,” replied Donald, just as quietly, “you know you ask the impossible. Let's not waste any more time over it. Decide what you are going to do with me—and do it!”
