One of the signature novels of the American 1960s, Couples is a book that, when it debuted, scandalized the public with prose pictures of the way people live, and that today provides an engrossing epitaph to the short, happy life of the “post-Pill paradise.” It chronicles the interactions of ten young married couples in a seaside New England community who make a cult of sex and of themselves. The group of acquaintances form a magical circle, complete with ritualistic games, religious substitutions, a priest (Freddy Thorne), and a scapegoat (Piet Hanema). As with most American utopias, this one’s existence is brief and unsustainable, but the “imaginative quest” that inspires its creation is eternal.
