This is yet another of Mr. Abe's ominous configurations (Woman In the Dunes, etc.) this time staking out its uncertain ideological imperatives in a grave new world submerged under water. In the beginning, however, Professor Katsumi who has a computer capable of making predictions of man's fate, has no idea of the work undertaken in a still more dehumanized laboratory. But a double murder, an analysis of one of the bodies, and some anonymous phone calls (this is all quite exciting) alert him to a traffic in human fetuses corroborated by his wife's enforced curettage. Witnessing the works in progress--growing rooms for human submarine colonies which will make man's survival possible--he is also threatened with his own extinction betrayed by his own machine and he is made to consider various ethical conjectures and priorities: should one deny one's self--should the present be expendable in the interest of the future? . . . . While not everybody's book, Mr. Abe's conceptual startler has a chilly precision which makes the unthinkable only too threateningly possible.
