It is revealed in "Sick Puppy" that Clinton has an older brother, Doyle. The two brothers went to Vietnam together. Doyle was discharged after a drunken joyride in a jeep led to a crash that killed his sergeant and inflicted serious head injuries on Doyle. The injuries, combined with guilt over the crash, led Doyle to suffer a nervous breakdown. After returning to the U.S., he left home and disappeared, becoming a homeless wanderer. When Clinton became governor, he tracked his brother down and gave him a job and home as the keeper of the (fictional) Peregrine Bay Lighthouse near Hobe Sound. In "No Surrender", Tile confides that Clinton "came into some money" a few years before the events of the novel, implying that Doyle had died and left his unspent state earnings to his younger brother.
