Laurence "Tubby" Passmore is a successful scriptwriter for a television sitcom, in his mid-fifties, married and the father of two grown children. He is indecisive and inexplicably depressed, unhappy with himself, his fat body, bald head, wonky knee, and impending impotence. At least, he is confident in his marriage to Sally, an attractive, self-made academic who enjoys sex; on weekly jaunts to London, he maintains a supportive but platonic relationship with the earthy Amy.

Seeking to alleviate his woes, he dabbles in acupuncture and aromatherapy and regularly attends a blind physiotherapist and a woman psychiatrist; the latter counsels him to write a journal. His wife suddenly announces her wish for a divorce and the television network invokes a contractual obligation to make unwelcome demands on his skills. These events shatter his unappreciated but complacent "angst" and deepen his identity crisis.

Laurence scrambles to rediscover himself. He reads the gloomy, Kierkegaard--because he identified with the titles--and he travels to the existentialist's Copenhagen. He pushes the boundaries of his relationship with Amy in a maudlin trip to Tenerife. He befriends a philosophic squatter, called "Grahame" (with an "e" no doubt to distinguish him from Graham Green whose "writing is a form of therapy" is an epigraph to this book). He flies wildly off to Los Angeles hoping to rekindle a one-night stand "manqué." Finally he recalls and tracks the Irish Catholic, Maureen, his first girlfriend from forty years before. Maureen has suffered too--the death of her son and breast cancer; he finds her on the Road to Compostella.
