Rapido Clint and J.G. Reeder — J.T. Edson

They called him Chopper, because of the way he destroyed his victims. But then he made a mistake. He gunned down two of the elite Company 'Z', then not only the boys of 'Z' were after him, but also Rapido Clint. The hunt spread to England, the trail of Mr. J. G. Reeder, and Clint and Reeder found they had an identical problem – to discover the identity of Chopper ... then destroy him!
