Whilst escaping from the police an elite gang known as The Phantoms callously kill an innocent family which brings them into contact with Lee Kemble, a Special Operations Operative and relative of the murdered people, who had been specifically chosen to find and eliminate them. He soon learns that he has not been told everything and finds that there is more to the case than was first thought for in the grounds of each of the houses robbed by The Phantoms the police had found a corpse, and the murdered people all had similar and unusual burn marks to their bodies. As Kemble gets closer to the gang he discovers that they are being paid by a mysterious woman who has a fixation with the number six and that everything is somehow linked to a letter written on the eve of his death in 1918 by a British soldier who had been charged with cowardice and sentenced to face a firing squad despite the fact that he was the victim of a gross miscarriage of justice and should have been feted as a hero. When he finally identifies the gang members, some of which were ex-colleagues, Kemble is shocked when they too are mysteriously killed and uncovers the unpalatable fact that the person who has taken it upon themself to exact revenge on the relatives of those people held responsible for what took place 1918 starts to take things further and what is more puzzling and disconcerting is the knowledge that his is the last name on a delayed retribution list. Kemble soon learns that friends and enemies can often be interwoven and that ultimately nobody can be trusted when one's life is in danger.
