Perfect escapism: why cosy crime stories are a Christmas essential

From Agatha Christie to Richard Osman, playful, quirky mysteries are particularly appealing at this time of year

A farce, for heaven’s sake! Everyone knows farce is dead.” When a character says these lines on page eight of Janice Hallett’s latest whodunnit, The Christmas Appeal, we can practically see the author tipping us an outsized wink. Hallett, after all, is one of today’s foremost exponents of cerebral, knowing crime. A swift 180 pages later, Hallett has slain another victim and shown that farce was never really dead in the first place. Literary murder – especially the cosy sort – has always been comic. The real mystery is: why is it so popular now?

Richard Osman’s Thursday Murder Club series, in which laughs, foibles and irony figure far more prominently than bloody murder, has topped the charts for four years running. The Crime Writers’ Association has just launched a new Whodunnit Dagger to honour the year’s best cosy, classic or quirky mystery. This Christmas, production company Mammoth Screen will bring us its latest Agatha Christie for BBC One, a reworking of Murder Is Easy that, like its predecessor Why Didn’t They Ask Evans?, plays up the love and laughs – moving away from the grittier cynicism of its earlier adaptations.
