As her mother is about to sell the family home and move in to a retirement village, Juno Mulligan is returning to the village of Inkbury to help out. Juno has asked her son Eric to look into the background of Dennis, her mum's gentleman friend. The result is that he has had three previous wives and they have all died in suspicious circumstances. Juno is convinced that her mum could be in danger.
Old College friend Phoebe Fredericks, who writes murder novels under the name of Dorothy De'Ath, is also living in Inkbury and Juno ropes her in to help her look for a house to buy. Phoebe is a bit of a hermit and keeps to herself and so doesn't really know very many people within the village or what may be available. When they meet up in the local pub for lunch there is an argument between a couple of the other guests and one of them ends up dead.
Juno, Phoebe and Mil, the landlord at the pub, team up together to find out who killed Si and why. Juno is convinced that it will be Dennis.
