4/5. DS Sue Manson of the Missing Persons Bureau continues her hunt for the religious art-fixated serial killer. The race is on to find the sixth victim before it's too late. The only clues are a cardboard triangle left at their home along with traces of a deadly zombie poison and a series of macabre photographs sent to a priest in South London, a Fr Raphoe. The priest has a passion for art history and he spots a connection between the weird photographs and a series of religious paintings by 17th-century Renaissance painter Nicholas Poussin. Written by Bill Murphy.
