A Helping Hand by Celia Dale

Josh and Maisie Evans are a seemingly unremarkable middle-aged couple on holiday in Italy, where they meet Mrs. Fingal, an elderly woman living unhappily with her niece. Josh and Maisie have a spare room, and everyone might be better off if Mrs. Fingal moved in with them instead. After all, they’re always glad to lend a helping hand. Especially to a lonely and wealthy old lady . . .

First published in 1966, Celia Dale’s A Helping Hand is a chilling work of psychological terror that explores the true evil that often lurks just behind a respectable façade.
