Five old university friends gather on the eve of their flatmate’s memorial at a beautiful riverside house. Host Caro is as perfect as always. Shy, awkward Lily’s now a bestselling author. Sports hero George loves suburban fatherhood. Bad-boy Travis only gets his highs from meditation. And gatecrasher Elle is still a troublemaker. Estranged for years, they’re finally ready to reminisce over dry martinis and delicious food. But there’s more than that on the menu… Because each guest is hiding a dark secret about their time at Oxford. They’re all guilty of something. Is one of them guilty of murder?
