Fail Safe: A Police Procedural Serial Killer Thriller

By Adrian Corso

The one who lived is the one who can prove it was never an accident.

When a target survives a sabotaged breakdown and triggers an SOS, she leaves Elliot Marsh something he has never left behind: evidence. A mechanic's affidavit names the tool marks. For the first time, the accidents have a fingerprint.

Naya Kaur finally has a task force, an affidavit, and a corridor of dead motorists that line up too cleanly to be chance. Then the warrant dies on a technicality - placement, not proximity - and a thirty-day clock starts running on the only case that has ever made sense to her.

Elliot doesn't panic. He engineers a fail-safe: two ways to die for every correction, so the next one can never walk out of the woods.

She has thirty days and a pattern no court will admit. He has all winter.

For readers of Thomas Harris, Tana French, and Jane Harper.

Methodical killer, forensic investigation, cat-and-mouse, cold case, dual POV, procedural crime thriller.
