In 1944, in the outer-Melbourne suburb of Nunawading, the brutal deaths of a family herald the return of a long-forgotten cult. A man named Anthony Prescott has declared himself the Messiah, and has promised his followers immortality. There are those who believe him - and who are ready to kill in his name.
Inspector Titus Lambert of the Melbourne Homicide unit, whose detectives are over-stretched, requests the discreet assistance of Helen Lord and Joe Sable: once members of his unit, now private inquiry agents. The investigation is more perilous than any of them realise, and will have tragic consequences.
