Lethal Catch: Crossing the Line. Sam Travis Adventures, #4

Massive shipments of pure uncut heroin are invading North America in 1989. So, Sam Travis of the Massachusetts State Environmental Police infiltrates the crew of a suspect sword boat within the commercial sword-fishing fleet that plies the waters off the Atlantic coast of Canada and the United States.  Though federal drug enforcement is not his job, Sam feels compelled to help crush this elusive smuggling ring.
He and the U. S. Federal Drug Enforcement Agency battle a cabal of cunning, well-funded, and ruthless international criminals who value money above all else. But they care nothing about human life. Least of all, his.  If this deep undercover mission fails, this insidious ring could incite a multi-national security threat-an eastern seaboard drug-induced epidemic. Or worse.
