Wicky's been called to a remote and windswept lighthouse off the coast of Ireland. The keeper's mate has been lost at sea, and Wicky has to clean up his personal belongings – just your standard sweep-and-clear. It should be an easy enough gig for Wicky, who's looking forward to the chance to escape the rat race and commune with nature a bit. But nature doesn't seem too keen to commune. The island is riddled with hostile seagulls and mysterious nautical legends, and home to an epically grumpy lighthouse keeper Brennan, who insists that dark and powerful forces are at work, and that all is not what it seems. Plus there's a folk song and a jellyfish. Wicky's got his work cut out for him.
