In a house built on lies, the truth will get you killed. London, 1953. Jimmy Sullivan lies dying on the drawing room floor while his housemates look on, their lives about to change forever. One foggy night in the dead of February, a young man arrives unannounced at 42 Tregunter Road in Chelsea. Self-styled Bohemian Mrs. Honor Wilson-who runs a minor literary journal and lodgings from this timeworn Victorian house-introduces him to her "dear house guests": Robbie, the writer; Mina, the teenage sleuth; George, the debutante; and Saul, the haunted refugee. Jimmy Sullivan is a family friend, Honor says-yet clearly, something is not right. Despite everyone's misgivings, she lets the stranger move into the attic. As they each try to disprove Jimmy's dubious account of himself, secrets, jealousies, and disturbing schemes come to light, fracturing the household's delicate allegiances and setting in motion, unstoppably, a tale of perilous self-invention, complicated love, and murderous revenge.
