It’s the holiday season, so naturally I need some suggestions of enthralling UK-based murder mysteries or police procedural books. Cozy like Louise Penny or grittier like Tana French. Creepy unexplained deaths and the awkwardly weird but forensically brilliant cast of tea-swilling, jumper-wearing (I’ll accept Canadians too, obv) characters who solve them. Cause that’s what Christmas is all about, Charlie Brown. Anyone?
