What She Saw

When a nine-year-old boy 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?
