Two deaths, 3,000 miles apart, put Erskine and Colby on the trail of Cosa Nostra boss John Duquesne. The first fatality occurred a decade earlier and the body was discovered during a routine military exercise near San Jose. The other is the killing a retired hitman on the other side of the U.S. The Cosa Nostra decides that Duquesne needs to get rid of his ex-wife, who could implicate him in the earlier killing. The FBI tries to connect the two murders and prevent a third.
