Katherine Dexter's brother is dead. It was heroin that killed him, but Katherine can't help but blame his death on the organized crime so rife in Italy. The drug trade may not make much money for the small-time pushers, the petty crooks, and the addicts. But for the men at the top--men like the Malaspigas, who run their yachts and their big houses on the profits of other people's misery--drugs are big money.   The Bureau of Narcotics are determined to nail these men once and for all. It'll be a dangerous enterprise, full of deceit. And they want Katherine Malaspiga Dexter to help them. . . .
