Cosy Crime Books for 2026: The Best Gentle Mysteries to Curl Up With

If you love a good murder but flinch at graphic violence, cosy crime is the genre for you. This guide is for UK readers who want gentle, puzzle-led mysteries to take on holiday, read by the fire, or gift to a parent or grandparent who prefers wit and warmth over gore. We'll explain what makes a crime novel "cosy", round up the authors leading the trend, and point you to specific titles worth adding to your shelf.

What is cosy crime, exactly?

Cosy crime (sometimes spelled "cozy") is a subgenre of crime fiction built around old-fashioned amateur detectives, a strong sense of place, and murders that happen mostly off the page. Richard Osman, Anthony Horowitz and Richard Coles are among the names spearheading the "cosy crime" movement: a subgenre of crime fiction that delivers mysteries with old-fashioned characters and a welcome dose of humour. One Dublin-based fan of the genre puts the appeal simply: "They're like a hug in a book, but one that keeps you turning the pages to find out what happens next".

The genre isn't new — Agatha Christie essentially invented the template decades ago — but it has found a fresh audience in the UK in recent years. Commentators have also noted a contrast with the darker Scandi noir that dominated shelves in the 2010s, with one Cork-based thriller writer suggesting that "the market prefers less 'unsettling' fiction in general" at the moment.

Why readers are drawn to it

There's no single verified sales figure to point to on cosy crime's popularity, but the reasons readers give for picking it up are fairly consistent in recent press coverage. One feature on the trend frames it as an antidote to a relentless news cycle, arguing that crime fiction might not seem an obvious panacea for the ills of modern living, but a new generation of authors is reconfiguring the genre with those real-life stressors in mind. It's a genre where, however tangled the plot, order is eventually restored — which is part of what makes it such satisfying escapism, whatever the actual sales numbers turn out to be.

If that sounds appealing, browse our Crime, Thriller & Mystery collection for a wide spread of titles, from cosy whodunnits to grittier reads for when you want more edge.

Richard Osman and the Thursday Murder Club

No UK cosy crime round-up is complete without Richard Osman. His Thursday Murder Club series follows a group of retirement-village pensioners who meet weekly to pick over cold cases, and it's widely credited with helping build the current audience for the genre. The first instalment was Osman's fiction writing debut, published in September 2020, and became a great financial success, becoming the No. 1 bestselling Christmas title in the UK, a first for a debut novelist. Osman has since continued the series and launched a spin-off, We Solve Murders, following a different set of characters.

These books make an easy entry point for anyone new to cosy crime, and they're a reliable gift for relatives who enjoy a gentle puzzle with plenty of humour. You'll find the series, alongside other big-name fiction, in our Bestselling Fiction Books collection.

A new name to watch: Sally Smith

One of the most notable developments in British cosy crime this year came at the 2026 British Book Awards, where Sally Smith's debut novel A Case of Mice and Murder won the British Book Awards Crime & Thriller Book of the Year 2026. The judges called the novel, set in London's Inner Temple, "exquisitely written" and a "standout in this category". They also praised Smith's detective creation, Edwardian barrister Gabriel Ward KC, as a new "memorable sleuth" on the crime and thriller shelves.

The novel marked Raven Books' first ever cosy crime series, launched with A Case of Mice and Murder, a debut introducing Edwardian barrister Gabriel Ward KC. It beat a shortlist that included Richard Osman's The Impossible Fortune, Dan Brown's The Secret of Secrets, Liz Moore's The God of the Woods and Chris Chibnall's Death at the White Hart. It's a good example of how the cosy crime lane now sits comfortably alongside the biggest names in commercial thriller writing, rather than as a niche sideline.

Other authors to explore

Beyond Osman and Smith, a growing shelf of UK and Irish authors are working in the cosy tradition — using small communities, hobbies (knitting groups, book clubs, village fetes) and amateur sleuths as their hallmarks rather than professional detectives or forensic detail. Anthony Horowitz and the broadcaster-turned-novelist Richard Coles have both been named repeatedly in coverage of the trend as key figures carrying the genre forward. If you enjoy the classic setup of ordinary people solving extraordinary crimes, it's worth working through a few different authors to find the voice and setting that suits you — seaside towns, rural villages, or city institutions all offer their own flavour of cosy mystery.

For a broader browse across crime authors old and new, our Fiction collection and Top Fiction collection are good places to compare what's currently popular.

Cosy crime as a gift

Cosy crime series translate particularly well into gifts, because the tone suits a wide range of relatives — from a teenage niece who loves a puzzle to a grandparent who wants something gentle for a long train journey. A boxed set of an established series, or a bundle of two or three titles by the same author, tends to go down well as a birthday or "thinking of you" present.

If you're buying for someone else, our Best Books to Gift collection and Box Sets & Collections are worth checking, since a complete run of a series often works out better value than buying titles one at a time — and at LetsBuyBooks, every copy is brand new, with UK delivery included.

How to start reading cosy crime

If you're new to the genre, a sensible approach is to start with one well-known series rather than jumping between authors:

• Start with the first book in a series (for the Thursday Murder Club, that's the 2020 debut) so you don't miss set-up details about the characters and their world.
• Look for signals in the blurb: a small cast of amateur sleuths, a village or close-knit community setting, and a tone that leans towards humour rather than dread, are all hallmarks of the cosy subgenre.
• If you enjoy one author, look at who else was shortlisted alongside them for awards like the British Book Awards Crime & Thriller category — shortlists are a reliable way to find similar authors you might not have come across yet.

Once you've settled on an author, our Books Under £10 collection is a low-risk way to try a new series without committing to a full-price hardback.

Final thoughts

Cosy crime won't be for every reader, but for anyone who wants a mystery that resolves neatly, without excessive violence, it remains one of the more reliably enjoyable corners of British fiction. Whether you start with Richard Osman's retirement-village detectives or Sally Smith's newly award-winning barrister-sleuth, there's a strong current crop of titles to choose from.
