A tidal surge revealed the past. Now Detective Sergeant Kate Brannon must uncover the truth. 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.
