When fire crews are called to a blaze at the home of a Kilwinnoch GP they make a grisly discovery: the charred remains of the doctor and his entire family.  But is this a tragic accident or an horrific, calculated murder?  DCI Duncan Bone’s worst fears are  confirmed when a cryptic message is found at the scene hinting at a grudge against the  medical profession.

A psychopathic serial killer may be at large in his home town.  The horror of the fire threatens to re-ignite dark memories of Bone’s own near-fatal assault.  And with an increasingly terrified community praying for the nightmare to end.  Bone knows that if he’s to stop the  flames from his past consuming him once and for all, he must do battle not just with a  homicidal maniac, but with the terrors inside his own mind.
