When a 9-year-old is left to die inside a burning car on a sink estate
in Peckham, DCI David Rosen is drafted in to investigate. The young boy
has been severely burned, and is now fighting for his life. As Rosen and
his team begin to scour the crime scene for forensic evidence, they
discover something chilling; a graffiti image of a sinister eye, drawn
in exquisite detail above the site of the wreckage - and behind it, a
series of mysterious markings, etched into the wall. Could the markings
represent a secret code left by the killer - a code that will hold the
key to the investigation?
