Start with The Thursday Murder Club. It is both the first published and the first chronologically, and unlike most crime series this one genuinely cannot be entered anywhere else — the mysteries are self-contained, the people are not, and the fourth book spends most of its length collecting a debt the first three ran up.
There is no publication-versus-chronological argument to settle here. Richard Osman wrote four novels about the same four residents of a Kent retirement village, in the order the events happen, and then started a different series with a different cast. The one warning worth giving in advance is about tone: these books get steadily darker as the characters age, and readers who arrive expecting four comic capers are usually caught out by the fourth.
The quartet, in order
The Thursday Murder Club (382 pages) introduces four residents of Coopers Chase who meet on Thursdays to pick over cold cases and then acquire a live one. It also establishes Joyce's diary as the narrative device, which is the voice the entire series is written in; enter anywhere else and the device arrives unexplained.
The Man Who Died Twice (404 pages) brings Elizabeth's past in the intelligence services to the village, along with a quantity of stolen diamonds. It is the book that demonstrates the series is not going to be four variations on one trick.
The Bullet That Missed (368 pages) takes the decade-old murder of a local television journalist as its case, but the significant movement is elsewhere: Elizabeth's husband Stephen has been declining in the background, and here that decline becomes the foreground.
The Last Devil to Die (400 pages) is an antiques dealer, heroin and the death of a friend. It is markedly the most serious of the four, it is a real ending to the emotional arc rather than another case, and almost none of it lands if you have not watched these people get three books older first.
Why the order genuinely is not optional
Cosy series usually tolerate dipping in and out, because the detective is a fixed point and the interest is the puzzle. Osman built his the other way round. The puzzles are competent and disposable; the continuity is in Stephen's illness, in relationships that form and end across the quartet, and in the accumulating awareness that everyone at Coopers Chase is closer to the end than the beginning. Read The Last Devil to Die first and you get a decent mystery with an oddly heavy atmosphere. Read it fourth and you get what it was built to be.
What Osman wrote next
We Solve Murders (461 pages) opens a separate series with a retired police officer and his daughter-in-law, a private bodyguard, and no retirement village at all. Same comic voice, much more mobile and thriller-shaped plot. Read it after the quartet — it is the test of whether you are following Osman or following the club.
The cosy tradition the club is standing on
The Murder at the Vicarage (1930, 256 pages) is Miss Marple's first novel. Elizabeth, Joyce, Ron and Ibrahim are four Miss Marples between them, and the original shows exactly which parts Osman kept. A Murder Is Announced (1950, 256 pages) is the best-plotted Marple and the closest to Osman in feel: a village, a comic surface, a genuinely cruel crime underneath.
Death of a Gossip (201 pages) is the first Hamish Macbeth, from 1985, and the bridge between Christie and the current boom. Our catalogue record credits Marion Chesney, which was the author's legal name; the books were published as M. C. Beaton.
The current shelf
The Marlow Murder Club is the closest direct comparison — three women in a Thames-side town, same amateur-team structure — and the obvious first stop. Murder Before Evensong, written by a former parish priest, does the community-portrait half better than most imitators. The No. 1 Ladies' Detective Agency predates the whole wave and is the warmest book here. The Appeal is the outlier, told entirely in emails and messages with the reader cast as investigator; last, because it is the least Osman-like thing on the list.
Where to stop
After The Last Devil to Die is a complete and deliberate ending. Everything past it is a new start rather than a continuation. The full ordered path, with a study plan for each stage, is at the Thursday Murder Club reading path.
