Gifford knows that he must get away: London, his office job, his suburban home and his older wife have become unendurable. When he is offered the job of handyman on a remote island, Gifford is happy to accept; but once there, doubts begin to creep in. What became of his predecessor, Mackie? And what secret lies inside the power house, which he has been forbidden to enter?
There is a dreadful mystery behind the isolated community on the island, and Gifford comes to realise that his own safety depends on remaining ignorant of the truth: that Mackie disappeared because he knew too much.
