An inspired concept — write about a group of contemporary amateur sleuths who are the same demographic as most amateur-sleuth mystery readers. Osman has created a high-end retirement community that’s a 21st-century version of the classic English village; even his title pays homage to the Golden Age mystery that introduced Miss Marple, Agatha Christie’s The Tuesday Club Murders. The characters are distinctive enough to tell apart, charming (or anti-charming) enough to be both likeable and suspicious, and similar enough to the traditional ensemble (the mysterious ex-spy, the logician, the friendly knitter, the garrulous working-class dad, the sharp and not-so-sharp local cops) to keep me laughing and turning pages. Osman is a professional entertainer and very good at it. I admired his acrobatic multiple not-quite-endings, though I didn’t entirely follow them, and I look forward to reading more from him — as well as the probable TV series.
