A psychopath goes to Harvard, and finds himself perfectly at home: this is a strange and unsettling reply to Love Story, Goodbye Columbus, and Portnoy’s Complaint. The Loner follows David Federman, a colorless grind, to Harvard. A good deal of the local detail is good, but Federmans, lacking much color or vast money, seldom get to Harvard these days. David’s physics-loving roommate belongs at MIT, and his intellectual girlfriend probably got into Brown but might well have gone to Smith or Williams. Then again, Federman’s beloved, his own private Daisy Buchanan, really does belong at Harvard. So do her friends. They probably deserve each other.
