Since investigating the disappearance of fifteen-year-old twin boys, Hingston - a young, talented Detective Sergeant, has been tormented by night terrors. On waking, he remembers a vast, golden meadow that glows with warmth and carries the sound of rapid footfalls and trouser legs pushing through grasses. A curly haired boy runs tirelessly through the meadow. The promise of adventure is lost when the sickening ache of death seeps into Hingston's bones. Feeling suffocated and tortured, melodic chimes calm him and his panic subsides. Signed off and leaving the office, a key inexplicably falls from Hingston's investigation file. Intrigued, he takes it with him, escaping London for Dartmouth where his investigative race begins. Stalked by a challenging elderly woman and hindered by his boss, his determination to solve the case draws him into the supernatural world that connects a murderous past to the present.
