Given the relentlessly grim nature of the news this year, it’s hardly surprising that escapism in the form of cosy crime continues to challenge traditional crime/thriller bestsellers, with Richard Osman’s third Thursday Murder Club mystery, The Bullet That Missed (Viking), riding high in the charts. The last 12 months have seen a bumper crop of excellent books at the cosy end of the spectrum, from Ajay Chowdhury’s second crime novel, The Cook (Harvill Secker), set against the backdrop of an east London curry house, to veteran Canadian author Louise Penny’s 18th Armand Gamache novel, A World of Curiosities (Hodder & Stoughton).
