"Powderfinger" is a present-day scary horror story set mainly on the decrepit, abandoned but soon to be redeveloped, bank of an old canal between two towns. It centres on an old tar works known as Raven's Gate. Nick Swann is a world weary mid-forties widower and Assistant Probation Warden at St Joseph's Hostel for young male criminals, situated overlooking the canal and Raven's Gate. A woman is brutally killed on the bank opposite the Hostel on a night when Nick is on duty. Nick believes his lads had nothing to do with it, though consequently Nick is suspended for issuing too many late passes at once. Then another woman is killed and Nick becomes drawn into discovering the culprit. He works with DCI Findlay and DS Deacon as the murder toll rises. Together with help from his old friends Alan and Hugo, Nick's research uncovers a long series of similar murders in the same area, stretching back through the centuries. "Powderfinger" as the killer is dubbed, appears to be some kind of ancient mellifluous, malevolent, murderous being that attacks anyone it considers to be disturbing its peace and quiet. Eventually, as the story climaxes, Findlay, Deacon, Nick and Alan set a trap to lure "Powderfinger" to his doom and rid the area of this beast once and for all. Yet, traps can swing both ways.
