The Fourth Protectorate

In an alternate 1984, the Brighton bomb kills the entire British Cabinet, triggering a spate of increasingly draconian laws that move the state towards a return of a Cromwell-style Protectorate. Amid mounting civil disturbances, Mark Barton's sole ambition is to bring down London crime lord Raymond Brown ('Mr Ray') following the murder of Mark's parents by Mr Ray's protection racket. Haunted by things that everyone else assumes are just symptoms of trauma, Mark's actions cause a power shift in the mob and an unexpected entanglement with a small, seemingly obscure government department divided by those pushing for a police state and those determined to retain a more moderate stance. Where should the line be drawn between justice and revenge or between maintaining peace and cruel necessities?
