This is a novel by a Swedish convert to Catholicism whose novels the publishers claim are a sensation in Europe. A reading of the present work inclines one to consider the claim credible. It is a profound religious and psychological novel about very modern, complex characters, including a brilliant French preacher who comes to the realization that he is actually without faith, a typical French agnostic doctor and an introspective, Scandinavian Catholic with cancer, who has almost given up the practice of his faith. The locale is Paris. Three other characters, truly spiritual and in genuine contact with reality psychologically, are sharply contrasted with the former three as they are made to enter into their lives to produce profound spiritual effects upon them. The style is simple and direct. In certain ways, the book is reminiscent of some of the works of the French Catholic novelist, Bernanos. It should have an appeal for the many readers who enjoy the latter's novels.
