DI Haig Crime Thrillers Books in Order

The DI Haig books take David J Gatward's crime writing in a slightly different direction. The first novel, The Somerset Slayings, introduces Detective Inspector Gordanian, Gordy, Haig at a moment when she is barely holding herself together. She arrives in Somerset grieving the death of her fiancee, out of place, exhausted, and unsure whether the move was a good idea. Unlike Harry Grimm, who meets the countryside with irritation and swagger, Gordy arrives raw and hollowed out.

That changes the feel of the whole series.

These books are still police procedurals, but they lean harder into atmosphere, unease, and the shadow side of place. Somerset matters here in the way Wensleydale matters in Harry Grimm. Ruined castles, quiet roads, woodland pools, village churches, roadside memorials, ancient customs, and rumors about the occult all seep into the cases. The crimes are grounded in human motives, but Gatward likes to let the air stay thick with superstition and dread while Gordy works through the evidence.

That is one of the pleasures of the series. Gordy is surrounded by whispers about ghosts, ritual, visions, and old beliefs, yet she remains a detective first. In The Somerset Slayings, murders echo scenes from horror films. In Hatchet Hill, the investigation brushes up against sacrificial folklore and occult history. Death Springs brings in wild swimmers, strange visions, and the uneasy pull of spiritual healing. Grave Omens starts with a roadside death and a disturbing clue that points back into the past. Blood Rites pushes further into village secrecy and ritual talk. The pattern is clear: the books enjoy eerie material, but they do not forget the police work.

Gordy herself gives the series its emotional center. Her grief is not a bit of background flavor that disappears after book one. It lingers. She is trying to do her job while carrying shock, loneliness, and the awkwardness of building a life in a new place. That makes the investigations feel personal without turning them into melodrama. She is vulnerable, but not soft. Dogged is probably the word.

There is also a nice sense that this is a series about starting over. New town, new team, new rhythms, new dangers. As the books go on, Gordy is not only solving cases. She is slowly learning what home might look like after loss. That thread gives the series weight, especially because the murders are often tied to communities with long memories and carefully buried resentments.

If you want crime fiction with a rural setting, a strong grieving lead, and a mood that sits somewhere between procedural and modern gothic, DI Haig is a good fit. Start with The Somerset Slayings. It lays out the emotional ground under Gordy's feet and shows exactly what kind of dark, Somerset-soaked world this series wants to explore.
