Life in the well-manicured London locale of Hexam Place is not as placid and orderly as it appears. Henry, the handsome valet to Lord Studley, is sleeping with both the Lord's wife and his daughter. Montserrate, the Still family's lazy au pair, is helping to hide Mrs. Still's illicit affair -- for a small fee. June, a haughty housekeeper, is hard at work forming a "society" for servants to address complaints about their employers. A disturbed gardener, Dex, believes a voice in his cellphone is giving him instructions. A deeply observed and suspenseful update to the upstairs/downstairs genre, this is Ruth Rendell at her incisive best.
