"What makes you think that?" Redmond said quickly.

"There are no powder marks on his face. And any one shot at such close range, by some one standing over him, would have had his head blown away."

Redmond assented, grudgingly.

"What does Plenty Buffalo think about it all?" he asked.

Lowell called the police chief and the interpreter. Plenty Buffalo declared that he was puzzled. He was not prepared to make any statement at all as yet. He might have something later on.

"Very well," said the agent, motioning to Plenty Buffalo to go on with the close investigations he had been silently carrying on. "We may get something of value from him when he has finished looking. But there's no use coaxing him to talk now."

"I s'pose not," rejoined Redmond sneeringly. "What's more, I s'pose he can't even see them Injun pony tracks around the body."

"He called my attention to them as soon as we arrived here," said Lowell. "But as far as that goes he didn't need to. Those things are as evident as the bald fact that the man has been killed."

"Well, that's about the only clue there is, as far as I can figger out," remarked the sheriff testily, "and that points straight and clean to some of your wards on the reservation."

"Count on me for any help," replied Lowell crisply. "All I'm interested in, of course, is seeing the guilty brought out into the light."
