Things are changing for Decker.

He's in crisis following the suicide of a close friend and receipt of a letter concerning a personal issue which could change his life forever. Together with the prospect of working with a new partner, Frederica White, Amos knows that this case will take all of his special skills to solve. Judge Julia Cummins seemingly had no enemies, and there was no forced entry to her property.

Close friends and neighbours in the community apparently heard nothing, and Cummins' distraught ex-husband, Barry, and teenage son, Tyler, both have strong alibis. Decker must first find the answer to why the judge felt the need for a bodyguard, and the meaning behind the strange calling card left by the killer. Someone has decided it's payback time.
