The first gripping story in a brilliant new series about a secret team investigating the strange, the mysterious and the unexplained. On a bitterly cold winter's night in 1900, a young boy disappears without trace from the forest near his home in the quiet village of Litton Cheney. He is never found, but the man he was with claims he was snatched by angels. Forty years later, Corporal Jack Carmody is sent to investigate strange reports of mysterious lights above Litton Cheney. The villagers suspect German bombers overhead, but Carmody knows there's something far more intriguing going on. And when a terrified boy appears in the graveyard, convinced it's the year 1900, it's up to Carmody and his boss - the charismatic Captain Holloway - to uncover the truth.
