Lucan

On November seven, 1974, the dead body of a children's nanny, Sandra Rivett, was discovered in a mail sack in the basement of a Belgravia townhouse. The suspect was the father of the children, Richard John Bingham, the seventh earl of Lucan.

A letter lands on Neil's doormat reporting the sighting of the missing aristocrat as a Buddhist monk in Perth in Western Australia. Neil and Glen go down under and immerse themselves in a network of Buddhist devotees.

Neil acquires the detailed medical notes of Lucan's plastic surgeon from more than 50 years earlier. He starts his own facial analyses. He finds a tiny nick in the nostril that he feels may be a crucial key to identifying Lucan.
