Lord Charles Sheridan and his American wife, Kate, have heard some truly awful things about Britain's most notorious prison. But Dartmoor and its mist-shrouded environs hold special appeal for both Sheridans. Kate hopes to find inspiration for her new Gothic novel, while Charles plans to implement a fingerprinting program at the prison - and arrange a meeting with one of its most infamous inmates, Samuel Spencer. He's convinced that Spencer - a Scotsman who admitted to killing his wife - is, in fact, innocent. What's more, he believes he has the evidence to prove it. But Spencer continues to maintain his own guilt - and, as if to confirm it, he soon stages a daring prison escape. Lord Charles and his acquaintance Arthur Conan Doyle are most perplexed by this odd turn of events. And when a body turns up on the moor, it's up to the two men - and the clever Kate - to discover if the missing convict is connected to this murderous new case...
