In December 1900, three lighthouse keepers vanished without trace from the remote Scottish island of Eilean Mor. An emergency relief crew was sent to man the lighthouse, and at the end of their month-long duty, they resigned from their posts, never to speak of what they had experienced. The mystery of Eilean Mor has never been solved. Until now. In the present, a group of environmental researchers arrives to observe the wildlife. While exploring the lighthouse, now deserted, one of the team discovers a manuscript written by one of the relief keepers, a man named Alec Dalemore. As a sudden storm cuts off their escape, the researchers come to realise that Dalemore wrote the manuscript as a warning to all who would come after him—a warning of something ancient and powerful and strange beyond imagining… The Lighthouse Keeper is a supernatural tale based on the Flannan Isles mystery, one of the greatest unsolved enigmas in maritime history.
