Inspecteur Lewis: Beyond Good and Evil

SYNOPSIS

A case from 13 years earlier returns to haunt Lewis when the evidence comes under review. Graham Lawrie was incarcerated in a secure psychiatric hospital after being found guilty of the murders of three police officers, but now the findings of the forensics lab have been called into question and an appeal has been launched. As Lawrie remains locked up ahead of his day in court, PC Mark Travis is lured to an isolated location with a hoax call and falls victim to a killer who uses the same weapon as that used in the original murders.
