""This is a superior series...""
The Night Hawks, a group of metal detectorists, are searching for buried treasure when they find a body on the beach in North Norfolk. At first, DCI Nelson thinks that the dead man might be an asylum seeker, but he turns out to be a local boy, Jem Taylor, recently released from prison. Dr Ruth Galloway is more interested in the treasure, a hoard of Bronze Age weapons. Nelson and his team believe the death to be an accidental drowning, but a second death suggests murder.
Nelson is in for a busy time when he is called to an apparent murder-suicide of a couple at an isolate farm house called Black Dog Farm. The house and its occupants are shrouded in mystery and will take all of Nelson detecting skills to unravel what really went on at the time of the shooting.
Local legend talks of a Black Shuck, a spectral hound that appears to people before they die, Nelson ignores this, even when the farm house owner's suicide note points to something buried in the garden and Ruth uncovers the bones of a giant dog.
All roads lead back to this farm in the middle of nowhere, but the place spells serious danger for anyone who goes near.
