The Other House (1896), by Henry James (novel)

The Other House is a novel by Henry James, first published as a serial in the Illustrated London News in 1896 and then as a book later the same year. Julia Bream dies after giving birth to her only child, a daughter named Effie. Julia had a horrible stepmother, so she extracts a promise from her husband Tony never to marry again as long as Effie is alive. Several years pass. Julia's old school friend Rose Armiger is in love with Tony, though she is ostensibly engaged to Dennis Vidal. In an effort to overcome the promise Tony made to Julia, Rose drowns little Effie so Tony will be free to remarry. The crime is discovered but family and friends decide to hush things up. Family physician Dr. Ramage convinces the authorities that Effie died of natural causes, Rose is sent off with Dennis Vidal, and all the people involved become, legally, accessories after the fact to murder...and they get away with it
