Robert Silverberg 
Blood on the Mink [EPUB ebook] 

SET A FAKE TO CATCH A FAKE… Somewhere in Philadelphia, a master engraver is turning out brilliant forgeries of U.S. currency plates for an organized crime. To bring the operation down from the inside, the government sends an agent undercover posing as a West Coast crime lord’s right-hand man. It’s a dangerous game of impersonation – one that could prove fatal when the agent’s secret begins to unravel… Unavailable for half a century ad never before published in book form, BLOOD ON THE MINK features a new afterword by the author discussing the novel’s origins in the pages of one of the last surviving pulp magazines – plus two of Silverberg’s short stories from the pulps, also appearing for the first time in more than 50 years.
