This is the first BBC Radio 4 series of "The consultants". Written and performed by Neil Edmond, Justin Edwards and James Rawlings, the series is produced by Will Saunders.
The first message sent to Tom Thorne's phone was just a picture - the blurred image of a man's face, but Thorne had seen enough dead bodies to know that the man was no longer alive. But who was he? Who sent the photograph? And why? While the technical experts attempt to trace the sender, Thorne searches the bulletins for a reported death that matches the photograph. Then another picture arrives.
