On a damp and dark London night a mysterious blue man lay murdered in a notoriously dangerous park. He was the ninth in a single year, albeit the only one painted blue. The local beleaguered police are on the trail and as their haphazard investigations proceed they embroil a very unlikely young man. Marion Morgansen is new to London and painfully naive, immediately on his arrival he finds himself hopelessly out of his depth amid manipulative gangsters and police detectives. However Marion is blessed or cursed with a very unusual mindset, quite alien to the hardened characters he meets at every turn. Confusion reigns first and then awe as the underworld crumbles around him. Some view him as an unlikely superman, others though, see him as the devil incarnate as the body count rises. All in all it is a bright and easy tale of valiant derring-do laced with the comical aspect of a very real world. As adversaries fall and others arise, hope and bewilderment become this young man's tools for survival, but are they enough?
