DI Callanach Books in Order

At its heart, the DI Callanach series is a story about two very different detectives learning to trust each other while dealing with extreme violence. Luc Callanach arrives from Interpol with a damaged reputation and a polished French exterior; Ava Turner is a lifelong Police Scotland officer who has grown up inside Edinburgh’s institutions and knows how its politics work. Their uneasy partnership becomes the spine of the books.

Each novel drops them into a new kind of nightmare. In the early stories they face a serial abductor who burns decoy bodies in the Highlands, a festival killer who uses city‑wide graffiti as a hit list, and a poisoner who enjoys watching victims fade away from a distance. Later investigations involve a killer turning women into human dolls, a manipulator who turns vulnerable people’s suicide attempts into murder, and a trafficking ring that moves between Scotland and continental Europe.

What ties the series together is not just the villains but the way Luc and Ava tackle them. Luc brings international experience and a strong moral code, but he also carries trauma from the false accusation that ended his Interpol career. Ava is sharper, funnier and more rooted in the city, often acting as his guide to how things really work in Scotland. Over time their professional respect deepens into something messier and more fragile, especially as their choices start to put each other’s careers and lives at risk.

Around them, a small cast of recurring colleagues and adversaries makes the world feel lived‑in.

DI Lively provides gallows humour and unexpected insight, while senior officers like Superintendent Overbeck add pressure from above. Journalists, hackers and victims’ families weave in and out of the books, sometimes helping, sometimes hindering. Fields uses them to show the ripple effects of each crime, making clear that a body on the page represents a whole network of people left behind.

The tone is darker and more graphic than many police procedurals, but it is grounded in believable detail from Fields’s own legal background. Crime scenes feel procedural rather than glamorous, and the detectives’ personal lives are messy in ways that never fully resolve. Edinburgh is more than just a backdrop: its festivals, old closes, student bars and bleak outskirts all shape the investigations.

Readers can jump into most of the books as standalones, but starting with Perfect Remains and following the published order lets you watch Luc and Ava evolve, case by case. If you like crime fiction that is fast‑paced, emotionally charged and unafraid to put its main characters through the wringer, this is a series designed to be read in long, tense stretches.
