A Killer in the Family

The Bonfire Killer has struck again, but this time is different. The pyre upon which he places his dead middle-aged female victims did not burn. It has been three months since the burned body of his previous victim was discovered, and DCI Jonah Sheens and his team are no closer to solving the case. However, their luck may be changing. Blood was found at the most recent scene, and while there is no DNA match in the system, they are trying something new: searching genealogy websites for possible matches. The results and further DNA analysis conclude that the blood belongs to one of four people: Aisling Cooley, her two sons, or her father, who has been missing since he ran out on the family in 1987. Have there been more murders with a similar M.O.? Will the killer strike again before he is caught? It is a race against time to identify and locate all suspects.
