December 5th, 2013 left its mark on the North Norfolk Coast in more ways than one. A tidal surge and storm swept millennia-old cliff faces into the sea and flooded homes and businesses up and down the coast. It also buried a secret in the WWII bunker hiding under the golf course at Brancaster. A secret kept for years, until it falls squarely into the lap of Detective Sergeant Kate Brannon and her fellow officers.A skeleton, deep inside the bunker.How did it get there? Who was he...or she? How did the stranger die—in a tragic accident or something more sinister? Well, that's Kate's job to find out.
