In the 1970 of this story, Eire has become an authoritarian police state, made somewhat acceptable to the population by the vast wealth flowing from a secret and forbidden science zone occupying a large area of the South-West. Here is based the mysterious 'Industrial Corporation of Éire' which has produced a range of new technologies. Its enigmatic founders are not Irish: they settled there and resist all attempts to find out who they are. A young British scientist agrees to be sent as a spy to find out just what is going on.
Although labelled as Science Fiction by the publisher, the bulk of the novel owes more to the thriller style of the John Buchan tradition, as the Cambridge hero battles across wild Irish landscapes fighting a series of murderous thugs and secret policemen.
The science fiction denouement is confined almost to the last chapter and foreshadows the theme of Hoyle's later A for Andromeda, though in a far more cursory manner. Also of note is the way the young hero seems to come to accept the notion of an authoritarian society ruled by a few self-appointed "supermen".
The link with the legendary Irish hero Ossian is peripheral to the plot and is explained near the end.[1]
