The Unforgiven (DS Mia McAllister #1) Release Date: August 5, 2026

Published

Rain-soaked Manchester. A detective who trusts no one, including herself. A killer who’s waited years to be fair.

Secrets can drown. Others learn how to kill.

When Chelsea Bainbridge is found stabbed and left in Manchester’s canal network, Detective Sergeant Mia McAllister is called to investigate. The evidence suggests Chelsea knew her killer, but the investigation quickly reaches beyond Chelsea’s final days.

When a second body is discovered, speculation spreads and pressure mounts. Anonymous messages begin providing clues the police cannot explain, while every new lead seems to raise more questions than answers.

As Mia digs into the victims’ lives, she becomes convinced there is something connecting them. Whatever it is, people have spent years pretending it never happened.

Someone knows what links the victims.

Someone knows who will die next.

The Unforgiven is the first novel in the DS Mia McAllister series, a layered Manchester crime thriller for readers who enjoy the investigative depth of Jane Casey, the psychological tension of Sharon Bolton, and the atmospheric mystery of Andrea Carter.
