Lowndes, M: Lodger by Marie Belloc Lowndes, Fiction, Mystery

Written in 1913, The Lodger was the basis for Alfred Hitchcock's first thriller, and a remarkable film it is. But the story Hitchcock tells -- of young love and mistaken identity (and is that a mistake, or malicious accusation by a rival. . . ) -- is very different from Lowndes's tale.
