Contemporary mysteries like Mare of Easttown, Only Murders in the Building, and All Her Fault are less interested in solving crimes than in exposing social fault lines—bad parenting, class resentment, institutional failure and collective guilt. It’s less about whodunnit and more ‘whydunnit’. This evolution has made the genre unusually attractive to mainstream actors. Figures like Craig, Winslet and Snook are drawn to stories that favour ensemble dynamics and morally frayed characters with greater tonal range. They are flawed and weary, far removed from their star avatars. For stars long trapped in hero-centric storytelling, the modern whodunnit offers a playfulness with characters that are allowed to be compromised without explanation or redemption. Today’s mysteries aren’t about clever reveals or brilliant detectives but about social unease, moral ambiguity, and emotional fallout.
