If you’ve fallen for the gentle charm, dry wit and quietly subversive brilliance of Richard Osman’s Thursday Murder Club series, you’ll know that crime fiction doesn’t always need gritty detectives or high-octane thrills to keep you turning the pages.

Sometimes, the most satisfying mysteries are solved over cups of tea, in seaside retirement villages, or between volunteer shifts and dog walks, by sleuths who bring a lifetime of experience (and a healthy disregard for authority) to the case.

Osman’s novels have sparked a renewed appetite for stories centred on older protagonists: characters who are often overlooked, occasionally underestimated, but invariably sharp as tacks. These are mysteries where wisdom trumps speed, where friendships are as important as clues and where humour and heart sit comfortably alongside intrigue.

Happily, there’s a growing cast of similarly delightful investigators waiting to be discovered. From retired teachers and crossword setters to monarchs, charity shop volunteers and reluctant dog sitters, these cosy mysteries prove that solving crimes is a pursuit with no age limit.

With its riverside setting, eccentric characters and cleverly constructed puzzles, the series has much of the same appeal as Osman’s work, celebrating friendship, independence and the joy of proving that age is no barrier to outsmarting a killer.
