Following a court appearance for drunk driving, Leo is required to perform unpaid work as a punishment, assisting AJ, a community worker on a run-down,largely black-occupied housing estate in South London. AJ is hoping to divert boys away from crime by encouraging them to do sports, and, though initially dismissive of Leo as a white intruder, comes to respect him after he has saved the life of Errol, a former gang member now anxious to keep his little brother Levi out of trouble. Errol has been stabbed in the leg by members of a gang from a rival estate and Leo stops him from bleeding to death. Earlier in the week a young girl called Shana Block was stabbed to death at a funfair and her murder recorded on a mobile phone. As Shana lived on the estate police sergeant Wallace involves Leo as a go-between with the suspicious residents. Also on the scene are Harry and Nikki, the latter dating Ryan, a young Scottish paramedic she met when called to the scene of Shana's death.

　　Chandler and Miles attend the launch of Buchan's book on murders in Whitechapel where they are baffled by cryptic remarks made by an eccentric old lady Louise Iver. At the same time elderly vagrant Alexander Zukanov is lured to a house with strange markings on the wall where he is pressed to death, giving the name Dorothy Cade to his killer before he dies. Miles and Chandler visit Zukanov's doss-house and learn that the other occupants were frightened of him and regarded him as a warlock. Buchan confirms that he was a member of the Bulgarian secret service and Stella Knight from MI6 names him as having been an interrogator of former British spy Crispin Wingfield. Wingfield is questioned but released though he tells the police that the manner of Zukanov's death was a punishment for witches in the sixteenth century. Meanwhile Dorothy Cade, living with her sister Cecilia, is also murdered, burnt at the stake like a medieval witch.
