Inspector Parry Books in Order

The Inspector Parry books shift David Williams from amateur detection to official police work, but they keep the same love of careful plotting and sharp social observation. Detective Chief Inspector Merlin Parry works in Cardiff and across South Wales, usually with Sergeant Gomer Lloyd beside him. Parry is patient, observant, and not easily rushed. He lets people talk, notices where their stories begin to wobble, and keeps pressing until the polite version of events falls apart.

That makes these novels feel more grounded than the Mark Treasure mysteries. Parry cannot simply stride into a room and take over. He has to follow procedure, test alibis, interview witnesses, and deal with the fact that rumor can cloud a case as easily as it can help one along. From Last Seen Breathing onward, the crimes grow out of ordinary places, market towns, suburbs, schools, clinics, and families that have been keeping secrets for years.

Small places remember everything.

A wealthy widow's death unsettles a Welsh town. A man returns from Australia to collect an inheritance nobody thinks he deserves. A blackmail scheme ends in murder in Cardiff's Central Market, with no useful witness in sight. A vicar's tangled personal life leads to a brutal killing. A school death that looks like suicide refuses to stay simple. An apparently kind and capable nurse is murdered at a private clinic. The books differ in detail, but the pattern is clear. These are stories about respectable surfaces cracking under pressure.

Parry is a good guide to that world because he is not written as a showy genius. His strength is steadiness. He is methodical, skeptical, and good at hearing what people are trying not to say. Gomer Lloyd gives the series ballast and warmth. Together they feel like working detectives rather than puzzle pieces moved around for convenience, and that helps even the more intricate plots in Death of a Prodigal, Dead in the Market, A Terminal Case, Suicide Intended, and Practise to Deceive land with real weight.

The Welsh setting matters on nearly every page. Cardiff is not just a name on the map, and neither are the nearby towns and villages. Williams understood how quickly gossip travels, how family loyalties and grudges keep shaping the present, and how class, religion, money, and embarrassment can all pull in different directions at once. The tone is a little darker than in the Mark Treasure books, but never grim for the sake of it. There is still dry wit, a good ear for speech, and a very clear sense of human absurdity.

Quiet places, messy people.

If you like traditional police procedurals with strong clues, human-scale stakes, and a real sense of community, Inspector Parry is a rewarding series. The books stand alone, but reading from Last Seen Breathing onward lets you settle into Parry and Lloyd's rhythm and see how Williams turned his attention from banker-sleuth puzzles to something more procedural, more Welsh, and just a touch more severe.
