4. Martyrs

Detective Chief Inspector Greave is leading a team investigating three linked murders in rural Norfolk - one of the lowest crime areas in the country.

Both victims had their heads shaved antemortem - and Greave discovers a link to a case in London a couple of years ago: the Dead List murders.

Next she receives her own Dead List but the names on the list don't belong to the victims but to Christian martyrs in the first century.

What's the connection?
