The Mellanbys, gentle people, open their home to Frank Roscoe, a stranger who saves Sally- and her son- from drowning, but he becomes unaccountable, unpleasant, and demanding (7000 pounds), toward some acquaintances- the Sherstons- as well. After a fight with Mellanby, Roscoe, who seemed stunned- dies- and it is Sherston who insists on burying him. Mellanby, reluctant at first, is the later victim of the elaborate deceit and there are unexpected repercussions and reparations to follow.... An old hand, Garve has not lost his touch but keeps it fresh- graceful and surprising.
