In the Yorkshire town of Bromersley there's a serial killer on the loose. Detective Inspector Michael Angel and his team of regulars search for the killer. However, the available clues are as sparse as they are puzzling: witnesses observe that someone, wearing early Roman attire, is observed at each murder, and a laurel leaf is left beside every corpse. DNA evidence links a woman of oriental origin to the murders, but this profile doesn't fit any of the suspects. The investigations become more mystifying as Inspector Angel races against the clock to find the killer. Can he prevent further bloodshed?
