A cat-and-mouse suspense thriller featuring Bill Hodges, a retired cop who is tormented by 'the Mercedes massacre', a case he never solved.

Brady Hartsfield, perpetrator of that notorious crime, has sent Hodges a taunting letter. Now he's preparing to kill again.

Each starts to close in on the other in a mega-stakes race against time.

1978: Morris Bellamy is a reader so obsessed by America's iconic author John Rothstein that he is prepared to kill for a trove of notebooks containing at least one more unpublished novel.

2009: Pete Saubers, a boy whose father was brutally injured by a stolen Mercedes, discovers a buried trunk containing cash and Rothstein's notebooks.

2014: After thirty-five years in prison, Morris is up for parole. And he's hell-bent on recovering his treasure.

Now it's up to retired detective Bill Hodges - running an investigative company called 'Finders Keepers' - to rescue Pete from an ever-more deranged and vengeful Morris...

Bill Hodges, who now runs a two-person agency called Finders Keepers with partner Holly Gibney, is intrigued by the letter Z written with a marker at the scene of the crime.

As similar cases mount up, Hodges is stunned to discover the evidence points to Brady Hartsfield, the notorious 'Mercedes Killer' who they helped to convict. It should be impossible: Brady is confined to a hospital room in a seemingly unresponsive state.

But Brady Hartsfield has lethal new powers. And he's planning revenge not just on Hodges and his friends, but on an entire city.

The clock is ticking in unexpected ways...
