Murder Comes in Threes — Marcia Mitchell

A Hollywood filmmaker is blown to bits aboard his sailboat - three weeks later, a controversial South Dakota judge is dispatched by a poison thorn. Another three weeks, and a popular televangelist is assassinated in Washington, D.C. Each had a list of enemies to rival the Manhattan telephone directory. Three clues are left behind: an overheard telephone call, a poison thorn, and a single bullet. All three cases end up in cold storage; then, nine years later, they land on FBI Special Agent Maggie Sachet's desk. In a flash, the bizarre cold cases heat to a single, sizzling danger point.
