While assembling a new exhibit featuring Art Brut or "Outsider Art," Dulcie encounters an enormously talented and equally troubled young man, Xander Bellamy. An autistic savant, Xander has not communicated with anyone for several months, since his father was sent to prison for the murder of Xander's domineering grandfather. Detective Nicholas Black thought the case was closed until Dulcie came to him with compelling evidence that the real killer was still at large. When evidence had originally pointed to Xander as the murderer, Xander's father had quickly confessed. Did he do this to save his son from being committed to a mental institution for the criminally insane? Xander's battle-axe aunt has come to live with him and, along with long-time family housekeeper Giselle, they see to his needs. But is there more to them than meets the eye? Meanwhile Dulcie seeks to see inside Xander's mind with the help of psychologist Dr. Raymond Armand. However, the ambitious Armand has other ideas about the lovely Dr. Chambers and is about to give Nicholas Black some competition when it comes to her affections.
