The Thursday Murder Club by Richard Osman (PB)

Set in a peaceful retirement village, four septuagenarians — who meet weekly in their “Thursday Murder Club” — spend their time discussing unsolved crimes. When a local property developer turns up dead under mysterious circumstances (with a strange photograph left beside the body), the club finds themselves thrust into their very first real case. As bodies begin to pile up, the unlikely team attempts to catch the killer before it’s too late. Cozy, witty, clever — this bestseller blends humor, heart, and a well-paced whodunit that makes it a favorite for fans of clever mysteries
