''Marvellous.' Susan Hill, The TimesElizabeth Reegan, after years of freedom and loneliness marries into the enclosed Irish village of her upbringing. The children are not her own; her husband is straining to break free from the servile security of the police force; and her own life, threatened by illness, seems to be losing the last vestiges of its purpose. Moving between tragedy and savage comedy, desperation and joy, John McGahern s first novel is one of haunting power. The details are evoked with a scrupulous yet enhancing accuracy that reminds one of the young Joyce. He is astonishingly successful in penetrating the mind of a mature woman confronted with pain and death. Mr McGahern is the real thing. Spectator
