Fissile Material [PDF ebook] 

When American secret agent Milo Stanich is found dead, agent Jack Wilson is sent to determine who killed him and to finish the job Stanich had been assigned: to keep a Pakistani scientist from selling fissile material to America’s enemies. In a wild, erotic tale of cross and double-cross that has Wilson working undercover to turn the Pakistani before the Russians can, Wilson beds the scientist, identifies Stanich’s killer, and brings his assignment-and the Pakistani scientist-to a satisfying climax!
