DCI Claire Winters Books in Order

The DCI Claire Winters series follows Claire Winters, a divorced detective chief inspector in the town of Haverbridge. She is the steady center of a set of dark police investigations, where a seemingly isolated death quickly points toward older harm, buried secrets, and someone prepared to hurt again. These are crime thrillers with a strong procedural spine, but the pressure also lands on Claire herself as every case demands time, judgment, and nerve.

For All Our Sins introduces her through the brutal murder of a priest. The crime appears to be driven by revenge, but the lack of clear evidence leaves Claire and her team chasing connections between the victim’s family, the past, and a growing number of deaths. It establishes the series’ main pattern: a determined detective facing a killer who has planned carefully and knows how to use other people’s secrets.

Haverbridge rarely stays quiet for long.

In The Principle of Evil, a body in a frozen lake signals a new threat. Another woman disappears, and Claire has to work out not only who is responsible but how that person thinks before the violence continues. The cases are unsettling without becoming detached from the people caught in them. Victims, relatives, suspects, and police colleagues all bring their own fears and blind spots to the investigation.

Trial by Execution turns public anger into part of the problem. When a former sexual predator is found dead in a way that echoes his crimes, many people see the killer as a vigilante rather than a criminal. Claire cannot afford that easy answer. A second death makes clear that the case is wider and more dangerous than it first appears.

The fourth novel, The Devil’s Letters, sends Claire into a heatwave case involving a posed body, an abandoned warehouse, and clues tied to a once-banned book. Across the series, Walsh uses grim crime scenes and escalating danger, but Claire’s work remains grounded in the patient task of finding links others have missed. Her role asks her to look directly at the worst parts of a case while still protecting the living.

Read the books in order if you can. Each mystery has its own central crime, but Claire’s personal life, working relationships, and accumulated experience carry forward. Readers who enjoy bleak police procedurals, serial-killer investigations, and detectives who keep going when a case gets personal will know what to expect.
