Back in 1701, one dark, windswept night, a young man hastened up the coast road to Tilbury Point. As he got nearer, a dark shape came into view. He raised his lantern to take a closer look and a gruesome sight met his eyes. It was a body, well rotted and covered in tar. The body was held in a metal cage attached to an iron gibbet. As the wind blew, the cage swung and the old chains creaked and groaned, almost as if the body itself was moaning.
