Members of the local church clergy in BExfordshire seem to be being murdered on specific church festivals, and it is up to DCI Matthew Wisdom and his team of detectives to track down the murderer. Matters are further complicated when they realise that there are some old cases from their own force and others that could impact on their current cases. Why would anyone want to murder members of the clergy in such a way? How on earth will they manage to stop the death toll rising?
