Killing Eve meets Jo Nesbo's The Snowman in this character-led crime thriller, in which a suicidal detective and a desperate hitwoman hunt a Neon-obsessed serial killer.

A detective desperate for revenge. A hitwoman with one last job. A killer with both on his list.

Detective Matt Jackson's beloved wife, Polly, is the latest victim of a serial killer - Neon - who displays his victims amongst snaking neon lights.

Suicidal but unable to kill himself, he hires someone to finish the job. But on the night of his planned murder he makes a breakthrough in the Neon case and offers his assassin, Iris, an irresistible opportunity: help Jackson find and kill Neon in return for his entire estate.

What follows is a thrilling game of cat-and-mouse between detective, assassin and serial killer. But when Jackson discovers it's not a coincidence that their paths have crossed, he begins to question who the real target has been all along...

The uncommon combination of cop and hit woman works well and the dynamic between the two proves fascinating with Iris showing wonderfully amoral Lisbeth Salander and Villanelle touches alongside a meticulous investigative process full of twists and fast running action. A definite page turner with a particularly poignant ending, this manages to give a tired sub-genre some new life (and crimes...)
