Havard & Lambert Mysteries Books in Order

The Havard & Lambert Mysteries are Welsh whodunits with one foot in village life and the other in police work. At the center is Fabia Havard, a former police superintendent trying to build a quieter life in Pontygwyn, and Matt Lambert, the detective chief inspector who once worked under her. Murder keeps dragging them back into each other’s orbit, and that push and pull is one of the things that gives the series its shape.

Pontygwyn is fictional, but it feels solid.

McCathie uses the Welsh valleys, nearby towns, old houses, riverbanks and community halls to make the setting matter. These are not books where the place could be swapped out for anywhere else. The weather, the gossip, the long memory of small communities, and the simple fact that everyone seems to know someone connected to the crime all help shape the tension.

Fabia is the unofficial half of the team. She no longer has the badge, and that gives her freedom as well as trouble. She can ask awkward questions, notice things other people miss, and move around as a neighbor, friend or curious outsider. Matt has to work within the rules, manage the formal investigation, and think about evidence that will stand up. He is steadier and more methodical. Fabia is more intuitive. Together they work because each sees what the other cannot.

That balance lets the series move easily between cozy mystery and police procedural. In Murder In The Valleys, the death of a local girl cracks open buried resentments. Murder at the Old Abbey turns to a difficult family and an inheritance mess around White Monk Abbey. Murder by the River Usk reopens an old disappearance after human remains are found near Caerleon. Murder in a Welsh Town brings murder into the middle of a pantomime and an undercover inquiry. Later books widen the circle again, from the suspicious death of filmmaker Geraint Denbigh in Murder of a Gentleman to the tunnel discovery and darker undertones of Murder of a Scoundrel.

What keeps the books grounded is motive.

These are not flashy puzzle-box mysteries built around impossible crimes. The trouble usually grows out of money, family, secrets, old grudges, local standing, or the kind of bad behavior that can hide for years in plain sight. Even when the stakes rise, the stories stay close to ordinary people and the knock-on effects a murder has on a town.

It is also a series that works best in order. The cases can stand alone, but Fabia and Matt change from book to book, and Fabia’s past is revealed slowly rather than all at once. McCathie’s own ties to South Wales give the books warmth and texture, and the sixth novel, Murder of a Scoundrel, was completed after her death from her unfinished work. That makes the series feel complete, but still closely tied to the life of the writer who knew these places so well.
