“Wuh.”

“See hyar, Cayuse; I don’t want no more o’ yer insinooations ’bout my shirt bein’ dirty. Mebbe thet thar dummy’ll save yer er shot in ther ’natomy.”

“Ugh! Bullet heap better.”

If Cayuse suspected the purpose of old Nomad he kept it to himself, and pretended to think the trapper pard’s mind was wandering.

As darkness settled fast they completed preparations by tying the horses to a jutting rock, then Nomad shouldered his mysterious weapon and crept along close to the inner wall. Cayuse followed near.

Nomad and Cayuse knew that if the men in ambush suspected they were creeping along the wall a shot might pot both of them, but they were taking the chances because they were aware it was Buffalo Bill’s wish to recapture Price and his partner in crime.

At any instant they might expect a flash ahead and feel the sting of a bullet.
