LONDON, SEPTEMBER 1915 When Constable Billy Rigsby, along with his mother and aunt, goes to the London Necropolis Railway Station at Waterloo, to attend the military funeral of a neighbour’s son, proceedings are interrupted by the unexpected and brutal murder of a young woman. In a panic, Billy telephones Mayfair 100, to assemble the team, and they descend upon the station to find not only a murder to investigate, but also two empty coffins, plus another coffin containing a headless and heavily tattooed body - obviously not the body of the young Captain whose name is on the coffin lid. The team then follow a trail of police corruption; a robbery that requires the assistance of the military police, and several violent crimes borne out of a selfish love affair. The investigations of the team take them into unusual and disturbing aspects of wartime life.
