Hampshire-born loner Johnny Pfoertner decides to return to his (partly) Scottish roots, so he moves to a remote island and sets up home. There he discovers, to the utter confusion of forecasters, that he can control the weather and in his mind becomes a reincarnation of the Celtic god Lugh. An encounter with a gullible bookmaker leads to fortune then a journalist, declared by him to be his 'goddess', brings him fame. But a showdown she sets up between him, the police and the Brothers of Caledon ends in disaster. Other characters include a pair of bemused forecasters and an improbable representative of ancient Scots. What starts as eccentricity leads inevitably to a sad, if satisfying climax.
