The Beach of Atonement [EPUB ebook] 

This is the story of a man who shot his wife’s lover and thus created a memory which wrecked his own life. Arnold Dudley loved his wife and killed the man who stole her from him. Hunted by justice, pursued by bitter remorse, he fled to a stretch of beach on the Australian coast and lived in utter loneliness. When almost driven to madness by the solitude, he meets two women, who strive to re-build his broken life… First published in 1930, by the creator of Bony, the Aboriginal detective.
