The Three Sisters of No End House — Mona Farnsworth

Janet Lowry believed she had at last found a haven from loneliness and despair with her cousins Addie, Mary and Elizabeth Hamlin. But within the bleak walls of their house lay a treacherous secret, for there was something profoundly sinister about the three old spinsters.

Even when she found comfort and the first taste of passion in the arms of Luke Hamlin, their estranged half brother, she felt an unnamed dread envelope her like a mist, and knew that she must penetrate the secret of No End House or face her own destruction.
