The small skiffs electric motor cut silently through the thick Norfolk Mist. They were following a tracker signal from a dart the ranger had shot into the large reptilian predator that had been eating the swan. The police became involved when a tourist fisherman went missing. The young policeman followed the silent hand signals from the ranger at the front of the Skiff. The mist lifted to reveal a rotten jetty and a teenage 'Downs Syndrome' girl, smiling at them. They moved slowly and spoke softly. Not out of respect for her disabilities but because cradling in her arms, like a new born baby, she held a large 12 bore shotgun.
