Inspector Angus Blue Books in Order

Inspector Angus Blue is at the centre of Allan Martin's west coast crime novels, a series that begins in Oban and keeps moving through the islands and harbours of western Scotland. The books visit places like Islay, Jura, Appin, Oban, and Mull, so the setting is never just wallpaper. Ferries, weather, tourism, local business, and the long pull of history all shape the cases Blue has to solve.

Blue is not a flashy detective. He is steady, thoughtful, morally stubborn, and more interested in getting to the truth than making life easy for powerful people. He works with a small team and relies on careful interviews, local knowledge, and patient digging. When a case needs specialist help, the books are happy to slow down and show how evidence is built rather than magically produced.

Place matters here.

The first novel, The Peat Dead, opens with bodies uncovered on Islay, and that tells you a lot about the series. These mysteries often begin with a striking crime, but the real story reaches backward. Wartime secrets, political deals, land, money, and old loyalties keep surfacing in the present. In The Dead of Jura a sniper killing leads Blue into obstruction and cover-up. In The Dead of Appin and The Dead of Oban, local cases open out into wider networks of corruption, trade, and theft. By The Dead of Mull, the danger feels close to home again, but the stakes are still bigger than one body.

These are police procedurals, but not cold ones. Martin gives you solid investigations and clues, yet he also pays attention to food, whisky, ferry routes, small talk, and the odd local character. The tone is serious without being grim all the time. There is dry humour running through the books, and Blue himself feels like someone who could exist off the page.

The west coast does a lot of the heavy lifting.

That is one of the pleasures of the series. You get the beauty of the islands and harbours, but also the sense that these are working places, with their own pressures, resentments, and memories. Outsiders arrive with money, influence, or bad intentions. Locals keep their own counsel. Blue has to navigate both.

Each novel has its own mystery, so you can read them one at a time. But it is rewarding to start at the beginning and watch Blue's world expand. If you like crime fiction with a strong sense of place, buried history, and detectives who keep going when the easy answer is clearly the wrong one, this series is a very good fit.
