Sergeant Mahon of the Mounted Police is missing; he had been sent to the foothills west of Edmonton where only Indians lived. Blue Pete is asked to search and rescue the Sergeant-if the Indians have done anything to the Mountie then they will all pay with their lives swears the half-breed. "If yuh sent the Mounties after the Sergeant they'd never git him alive," said Blue Pete. "Them Neches 'ud do him in quick, an' thar's a million places to bury him whar nobody'd ever find him. I'm goin' to git him, Inspector. If they've done for him thar'll be so many notches on my guns I'll have to git new ones to hold 'em." This was the prelude to another of Blue Pete's amazing escapades-one which will undoubtedly thrill the many thousands to whom Blue Pete is known as the most popular and colourful cowboy in fiction.
