When one of her most loyal henchmen, Jacob Cromart, is murdered in St Michael''s Church, where he had claimed sanctuary, Margaret orders her sharp-witted clerk, Christopher Urswicke, to find out who has betrayed her.How could a man be killed inside a church where the doors are all locked, with no sign of an intruder or weapon? If he is to protect Margaret''s remaining supporters from suffering a similar fate, Urswicke must solve a baffling mystery where nothing is as it first appears.
