With the papers near the mutilated body of Harry Seton is a note: "Ask Coffin." Seton was a detective doing undercover work on the sale of illegal pharmaceuticals. No one， including John Coffin， Commander of London s Second City， knows what the note means， but it appears that Seton was secretly investigating internal police corruption. Coffin begins to look into Seton s secret investigation， only to find that someone has beat him to it and is already destroying evidence that the commander will need. Just as Coffin starts to follow Seton s trail， a far greater tragedy strikes Second City. Four boys， each connected to the police in some way， are missing and the body of one is found buried in a shallow grave. It is clear that someone who holds a grudge against the police has targeted the children， but there is little evidence to go on. The only witnesses are a group of rollerbladers， but fear and something else are keeping them quiet. The terror in Second City comes directly to Coffin s house， threatening him and his wife Stella. Is it Harry Seton s nemesis seeking him out? Or the child-killer? Or are they connected? Is Coffin cunning enough to avert any further disasters?
