Doctor Stephen Forshaw belonged to one of London's oldest and wealthiest families. We learn that one day Doctor Forshaw simply vanished into thin air. Only to be followed one year later by his sons, Robert, Angus and Toby. No motive or clue to their disappearances was ever discovered by the Police and their bodies were never found. Despite this, the authorities secretly believed that all four were dead and were certain that it was only a matter of time before their bodies were discovered.............
Almost ten years to the day Stephen was discovered missing, a boy matching Toby's description reappears at a disused farm in Hertfordshire. The boy has no memory of where he has been and doesn't even know his name. The Boy cannot understand why he hasn't aged one day in nearly a decade. He is only aware that his life is in grave danger.......
