Kathleen Norris. Mystery House (1939) 305 pp.
Page Hazeltyne is a young woman, trained as a nurse but currently at loose ends. She is living in a boarding house in San Francisco and longing for adventure when she is offered the job of caring for Mrs. Prendergast, a wealthy, eccentric, elderly woman living in a large, secluded house on the coast south of Half Moon Bay. The house, which has been under construction for decades, has been given the moniker Mystery House and, as far as Page is concerned, it certainly lives up to its name. The other residents of the house include: Flora Mockbee, the sulky daughter of Mrs. Prendergasts previous companion, who died mysteriously several months earlier; Rand Harwood, a handsome doctor recently arrived from an extended stay in China who is staying on as Mrs. Prendergasts personal physician; and, Lynn, a gentle young man who is suffering from a mysterious mental illness. Page soon discovers that the famous Prendergast diamond, a fabulous pink stone the size of a pigeons egg named the Ked Anna, is missing. She also discovers that some people are willing to kill to possess it. Editors note: Although set on the San Mateo County coast, the titular Mystery House is clearly inspired by the Winchester Mystery House in San Jose, with many of the same qualities: perpetual construction, numerous rooms and hallways with secret passages, and a séance room.
Setting: San Mateo County (south of Half Moon Bay, near Pescadero), San Francisco
