Winter kills

When President Timothy Kegan is shot in a Philadelphia motorcade, a presidential commission condemns a lone psychopath as the killer. Fourteen years later, Tim's half-brother, Nick, learns through a deathbed confession that Tim was the victim of a mysterious conspiracy. As Nick attempts to find the real assassin, he encounters oil kings, movie queens, venal police, organized crime, the CIA, and labor unions -- all eager for power and control.
