Marie Belloc Lowndes

Marie Adelaide Elizabeth Rayner Lowndes (née Belloc; 5 August 1868 – 14 November 1947), who wrote as Marie Belloc Lowndes, was a prolific English novelist, and sister of author Hilaire Belloc.

Active from 1898 until her death, she had a reputation for combining exciting incidents with psychological interest in her books. Four of her works were adapted for the screen: ''The Chink in the Armour'' (1912; adapted 1922), ''The Lodger'' (1913; adapted several times), ''Letty Lynton'' (1931; adapted 1932), and ''The Story of Ivy'' (1927; adapted 1947). ''The Lodger'' was also adapted as a 1940 radio drama and 1960 opera. Provided by Wikipedia
