When burned-out investigative journalist Adam Budd's estranged mother dies, he inherits her estate. This includes Stone Heart House, a huge ramshackle mansion on a remote Scottish island. He visits the island to sort out her tangled affairs, and at first it seems like a charming haven of tranquillity. But after he witnesses a strange accident, he begins to develop suspicions about the inhabitants. Why does everyone seem so eerily calm, even under stress? What is stopping Harriet, the lawyer helping him with his affairs, from leaving the island when she so clearly wants to? Is he making a big mistake by falling for her? And why have so many children gone missing? Stone Heart Deep is a compelling and claustrophobic thriller with a remarkable twist, as if Iain Banks had rewritten The Wicker Man.
