The Crumbles Murders are two separate and unrelated crimes which occurred on a shingle beach located between Eastbourne and Pevensey Bay, England—locally referred to as "the Crumbles"—in the 1920s. The first of these two murders is the 1920 bludgeoning murder of 17-year-old Irene Munro, committed by two men: Jack Field and William Gray. The second murder to occur upon the Crumbles is the 1924 murder of 38-year-old Emily Kaye, who was murdered by her lover, Patrick Mahon.
