On a wild Cornish headland, Catherine Carlyon takes a decision that will change her life forever. She is facing the bleak prospect of years in prison after being sucked into a fraud by a man she thought loved her. Catherine has found a possible way out – to disappear. But disappearing comes at a price. She must abandon her family and everything she holds dear. The greatest challenge of her life is looming, an epic adventure in the North Atlantic which will take her to her limits and beyond… Praise for Hidden Depths: 'A conventional middle-aged woman has a passionate affair, becomes embroiled in fraud and makes the desperate decision to risk all in the hope of disappearing. J.H.Mann has lovingly evoked the Cornish landscape, from the wild Atlantic coast to the bleak and threatening moors, as the setting for a gripping thriller. I loved it’ – Debi Alper, author of the Nirvana series of thrillers. ‘The real essence of the challenge of open water swimming has been woven into a finely crafted suspense novel’ – Mark Richards, long distance swimmer, one of the few people to have successfully completed the 28-mile swim between Cornwall and the Isles of Scilly. Perfect for fans of Ann Cleeves's Shetland and Vera Stanhope mysteries and novels by Lucy Foley and Alice Feeney.
