The Keys is a suspense-filled thriller in which police detective Mac Forrester must solve a string of homicides as well as come to grips with the brutal murder of his wife nearly two years before.
Set in Southwest Florida, the story opens with Forrester piecing together clues from separate murders and attempting to link the crimes together. His investigation is hampered by what appears to be interference on the part of the FBI on behalf of mysterious entrepreneur A.J. Hidell.
Forrester gets his first break in the case while interviewing the girlfriend of one of the victims. She gives him the key to a post office box which triggers a search that takes the detective to the Florida Keys.
Forrester begins to discover whom he can and cannot trust on his way to discovering what The Keys really are, how much they are worth and to what extent people will go to obtain them.
The climax of the story features a final confrontation between Forrester, the head of a Cuban drug cartel and Hidell, whose mysterious past may include ties to Lee Harvey Oswald, one of the most notorious assassins of the Twentieth Century.
