Hestyn is a coastal town untouched by time. As more and more destinations fall victim to war and terrorism and are crossed off his beloved maps, travel writer Wilf Bromley finds himself exploring its dubious delights for his next book, Gems of the Coast. It's a far cry from his past expeditions with Aggie, his feisty co-writer. But Aggie has disappeared, and Wilf's visit to this bleak place is taking a very strange turn, as he's drawn into the bizarre world of landlady Gwen, local historian Warren and the mysterious B&B guest Martha Crick. Then there's the abandoned old manor house on the cliff, which harbours more secrets than any guidebook could contain. The more Wilf investigates this particular hidden gem, the more we discover about his own confused private life.
