1978 young adult offering from Charlotte MacLeod. The last of MacLeod's young adult mysteries before starting her better known adult series of humorous cozy mysteries. It's 1908 and Letitia Tabard, "getting on for twenty ...", has finally been removed from boarding school and sent to live with wealthy cousin Zilpha Tabard and her companion, Tetsy Mull. Zilpha is isolated from reality but has very definate ideas of what is proper. Tetsy is devoted to Zilpha and resents the arrival of Letitia. Zilpha is renovating a property purchased from Jonah Jenks, who went missing seven years ago. Her property is also occupied by a two man architectural firm; the firm was owned by Jenks and willed to Ronald and Hayward, but they can't move it until the missing Jenks is pronounced dead. Zilpha finds Ronald is a distant relative and attempts to match him with Letitia, a move to Ronald's liking since it would move him closer to Zilpha's prestige and money. Letitia, however, forms an attachment with Haywood, the socially unacceptable son of a carpenter. Letitia's inquisitiveness creates friction and raises questions about the fate of the missing Jenks.
King Devil, the name ascribed to the dandelion-like flower found on the grave of a Jenks ancestor, is a colloquial name for Hieracium caespitosum, also known as Yellow Hawkweed.
Non-series - YA - The last thing Lavinia thinks she will encounter when she goes to live with rich cousin Zilphia in 1908 is mystery and romance.
