"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.
