The book opens as the protagonist, Adrian Healey, and his mentor, Professor Donald Trefusis, are at Mozart's birthplace in Salzburg, where Adrian witnesses the murder of their contact. The narrative then shifts to Adrian's time at public school, where he has carefully groomed himself to convey the image of a witty, highly extroverted young gay man; however, despite his image, and, despite regarding sex as his "public pride", he finds himself unable to express his love for the beautiful Hugo Cartwright. Another student, Paul Trotter hangs himself due to his unrequited love for Adrian. Adrian is shown later in the novel to be touchy on the subject of suicide as a result. Prior to Trotter's funeral, Adrian has a sexual encounter with Hugo while pretending to be asleep. Adrian is later expelled from school for writing an article discussing the tradition of hidden behaviours that could be considered homosexual at public schools; consequently, he takes his A-level examinations in a Gloucestershirestate school. Adrian claims to have run away from home due to unhappiness, subsequently becoming a rent boy, but it is later revealed, in an overheard conversation, that this probably never occurred. Eventually, Adrian takes on the role of schoolmaster and has his first sexual encounter with a woman, a fellow member of staff at the school. The school years finish with Adrian's cricket team defeating the team of Hugo Cartwright, to whom Adrian no longer feels attracted. Just as Adrian and his team are about to leave the school at which Hugo is a master he admits to Hugo that he was awake during the incident before Trotter's funeral. Adrian attends the fictional St. Matthew's College, Cambridge and is given a challenge to produce something original by his tutor Professor Donald Trefusis. With the aid of his girlfriend – and later wife and acclaimed producer – Jenny de Woolf, and his housemate Gary, he writes and claims to have discovered a lost manuscript by Charles Dickens which dealt with the child sex trade. The discovery brings Jenny and the college fame, but it also results in a dialogue between Adrian and Hugo, who has become an alcoholic. Hugo believes that Adrian hates him, and points to Adrian's duplicity as proof. Adrian corrects him and the two leave things on a friendly note. After graduation, Adrian attends a farcical meeting where he and other attendees discuss the arrest of Trefusis, who was arrested on charges of cottaging, sabotaging the footage of an onlooking BBCfilm crew. It is later revealed that he was actually undertaking a document exchange preceded by two kisses on the cheek as is custom in several European countries, such as Hungary. Adrian joins Trefusis in a forced sabbatical, which they claim to spend studying the fricative shift in English. In actuality, the year is spent in a game of espionage in which they must acquire the parts for Mendax, a lie-inhibiting device from his Hungarian friend Szabó. A showdown results with Adrian's uncle David and Trefusis, during which it is revealed that Pearce's aide was a double agent working for Trefusis. It is also revealed that the murders that Adrian witnessed were staged to scare Trefusis into giving Mendax to MI5, and that Mendax was fictional. Subsequently Adrian overhears a conversation between Trefusis and Pearce where it is revealed that the espionage adventure was just a game to counter boredom, meaning that several parts of the story were untrue. Adrian remembers a letter written to him by de Woolf saying that while young girls grew up, young boys did not, making their education irrelevant and just a game. The book concludes with Adrian, now a Cambridge fellow, recruiting a new spy for a new game.
Autobiographical elements
The novel is semi-autobiographical and many scenes echo experiences later recounted in Fry's memoir, Moab is My Washpot. The character Trefusis was created by Fry for several humorous radio broadcasts on BBC Radio 4's Loose Ends.
Conceits
The espionage portions of the book are written in italics, which stop at Adrian's graduation. The book features a third-person omniscient narrator. The narrator knows, for example, about David Pearce's annoyance at Dickon Lister's ignorance of the story of Helen of Troy. Starting with chapter four, in keeping with popular spy fiction, the characters refer to each other by code names; in this case, the names used are from the Trojan War:
Adrian is "Telemachus", the name of the son of Odysseus in the Odyssey
The author is renowned for his interest in the English language. In a post on his blog, Fry talks about the evolving language, including his interest in "verbing" nouns. He also reproaches grammar pedants. In the book there are several experiments with the English language, mostly used in the dialogue. These range from several nouns used as verbs, Americanisms to polysyndeton. In the book, at school, Adrian actively tries new vocabulary. As a spy he is told off by Trefusis for saying "it is them" instead of "it is they" and complains to Trefusis about the habit of another character of overusing the suffix "-ise" like an American.
Reception
The book is noted for its wit and humour, as well as its often outrageous references to various homosexual experiences. The book also has an unreliable narrator: Adrian is 'the liar' and lies habitually to other characters; accordingly, in the book, whole chapters are later revealed to be fictitious, though the reader has no prior warning. This manner of sudden revelation occurs at various points throughout the book, placing respectable characters in scandalous situations and juxtaposing humour and triviality with darker themes.
