It's a stormy December morning when seal-watchers find the body on the beach at Winterton-on-Sea. His clothes have been torn to shreds on the rocks. The bright-orange life jacket didn't save him in the end. Detective Sara Hirst races to the scene. The washed-up body turns out to be a deckhand who got swept overboard in a storm. It looks like a tragic accident. Until another body is found on a pleasure boat drifting out at sea. There are bullet holes in the boat's hull. This was definitely murder. But Sara will soon have more to worry about than two dead bodies. Someone from her past is back . . . There are dark dealings going on in this quiet stretch of Norfolk coast. Detective Sara Hirst must catch a killer before anyone else turns up dead.
