Purity

Two prostitutes, a pimp, a drug addict and a tramp, have all been identically strangled in the city, and the phone lines are buzzing. Just as it seems a morally righteous serial killer is cleaning up the streets, an arson attack at a Camden hospice takes eleven patients to their deaths earlier than expected, and every atrocity becomes united by a chilling bond. Someone out there is not only very sick. They are killing the sick.
