Blood on the Mink

Somewhere in Philadelphia, a master engraver is turning out brilliant forgeries of U.S. currency plates for an organized crime gang - and the government wants to put a stop to it. But how can they get close enough to bring down the criminal enterprise from the inside? 

By snatching a west coast crime boss' right-hand man and sending a federal agent undercover in the man's place. His assignment: pose as a buyer of counterfeit bills and try to get the engraver out. Which works fine - until he crosses paths with someone who knows the man he replaced... 

A lost masterpiece from science fiction Grandmaster Robert Silverberg, published as a complete novel for the very first time!
