Garth's lady-friend told Kevin and Lucy that before Garth turned up dead he had been talking to a creepy stranger. Lucy asked her to describe him. Kevin sketched the man from her description and was surprised when Lucy chimed in. She confessed that a similar sounding man had turned up at the Lighthouse and though he hadn't done anything wrong, she'd received bad vibes from him. When Kevin was done sketching, he had drawn an accurate picture of Caleb. Kevin was in full investigative mode as he and Lucy tried to figure out who the man in the sketch was.  He and Lucy realized that there was something inside that the man wanted.  (July 12-13)
