Cambridge University

Cambridge University is the professional home of Andrew Martin, the mathematician whose identity the alien narrator assumes, and one of the principal settings in which that impersonation takes shape. To the narrator, the university is at once a place he must navigate and an institution bound to the proof that brought him to Earth: its buildings and routines make Andrew’s life tangible, while its academic world holds the mathematical result the narrator has been ordered to erase.

The university and the unfamiliar town

The narrator arrives with facts about Andrew supplied across space: Andrew is a forty-three-year-old professor at Cambridge University, a husband and father who has spent eight years pursuing a famously difficult mathematical problem. The identity is not his own; Andrew is, as the narrator understands it, a role necessary to complete a task. Yet the assignment makes the university an immediate part of his borrowed life. He is to inhabit the career as well as the name, and the institution’s ordinary places become tests of whether he can pass as someone who belongs there.

By morning, the narrator is in Cambridge, a place he is expected to treat as his own despite finding it profoundly alien. Its buildings strike him first. He has to adjust to structures fixed to the ground, and to the fact that this is supposedly the town where Andrew has lived on and off for more than twenty years. The mismatch between the narrator’s knowledge of Andrew and his physical disorientation gives the university setting a double aspect: familiar to the person he impersonates, but startlingly strange to the consciousness inhabiting that identity.

The first vivid encounter with the institution comes in the rain. Seeking shelter, the narrator passes a large building with a gate and a sign naming the College of Corpus Christi and the Blessed Virgin Mary; a second sign identifies Cambridge University. He uses his left hand to open the gate and crosses onto wet grass, moving toward a building where lights remain on. The scene makes entry into the university literal, but not comfortable. Rain on his skin and hair feels horrific, and the damp grass repels him. The campus offers signs of life and warmth, yet his first bodily experience there is exposure and distress.

The college as workplace

The university is also a workplace the narrator must re-enter under pressure. On a Sunday evening, after learning from television that rain is not expected, he rides Andrew’s bicycle to Fitzwilliam College. He expects Isobel to be at the supermarket and knows he has limited time. Even the journey requires improvisation: cycling is relatively easy, but uncertainty about road rules brings him close to accidents. The episode places the impersonation inside mundane practical knowledge, rather than in any grand academic performance.

At Fitzwilliam College, he reaches a quiet, tree-lined street called Storey’s Way and approaches the main entrance of the largest of three buildings. It is a relatively modern, three-storey structure. A woman is mopping the wooden floor as he enters; she appears to recognize him, but the recognition does not make her happy. The narrator responds with a smile, having learned that it is an appropriate greeting, then claims to be Professor Andrew Martin and says that a minor accident has caused short-term memory loss. He asks for directions to his office, describing what he needs as something of personal value. The exchange shows how the familiar institution can expose the gaps in his disguise: a colleague or employee may recognize Andrew even when the narrator does not understand the history carried by that recognition.

Andrew’s office turns professional identity into an arrangement of objects. When the narrator returns later, no longer in a hurry, he notices books lining every wall, positioned so that Andrew would be seen with a book from whichever angle someone looked at him. The titles include works on binary and other non-decimal numeration, hyperbolic geometry, hexagonal tessellation, and logarithmic spirals and the golden mean. Among them is Andrew’s thin book, The Zeta Function, marked as an uncorrected proof copy. The office is therefore more than a room he must locate: its contents materialize the mathematical career he has inherited and the intellectual work central to his mission.

The academic community

Cambridge University connects Andrew to Daniel Russell, the recipient of a crucial email in Andrew’s sent folder. The message asks Daniel to examine the attached proof of the Riemann hypothesis before it becomes public. The narrator discovers that Daniel is the university’s Lucasian Professor of Mathematics, aged sixty-three, an internationally successful author of fourteen books, and a scholar who has taught at prominent English-language universities, including Cambridge. Andrew and Daniel have worked on several academic papers together, though the narrator judges them to be colleagues more than friends. Their relationship makes the university’s academic structure consequential: the proof is not merely Andrew’s private discovery but a claim entrusted to another mathematician for scrutiny.

The narrator acts to prevent that scrutiny. With Isobel due home soon, he deletes the email and its attachment, then designs a virus using prime numbers to ensure that nothing on the computer can again be accessed intact. His actions turn the university’s scholarly network into an obstacle to the task he is carrying out. The place that gives Andrew’s achievement its professional meaning also contains the channels through which that achievement could be confirmed and shared.

That tension continues in the lecture hall. The narrator enters a large room filled with students waiting for knowledge; he counts 102 people, an unsettling number to him because it falls between two primes. He studies their apparent level of understanding, wary of teaching beyond it, and faces a blank whiteboard. Before he can begin, a student at the back appears to sense his hesitation. The scene puts the professor’s public role under a different kind of test from the office encounter: here, belonging depends not on knowing where a room is, but on being able to stand before students and speak with authority.

Everyday campus life and narrative significance

University life also appears in less formal spaces. A little later, the narrator sits in the college café with Ari, drinking grapefruit juice while Ari has sweet coffee and beef-flavoured crisps. Ari asks how the lecture went. The café setting links academic performance to conversation and ordinary companionship, while the narrator’s effort to avoid Ari’s cow-scented breath recalls how persistently he experiences human life through unfamiliar bodily details. The institution is not only a hierarchy of professors, research, and classrooms; it is also a place where people meet over food and ask how the day went.

Taken together, these locations trace the narrator’s gradual occupation of Andrew’s institutional identity. The gate at Corpus Christi, the office and its books, the lecture hall’s expectant students, and the café with Ari each demand a different kind of participation. At Cambridge University, impersonation cannot remain an abstract premise: it must be enacted through movement, professional knowledge, social cues, and decisions about who may see the proof. The university’s significance lies in that convergence. It is where Andrew’s mathematical life is most legible, and where the narrator’s attempt to erase its consequences unfolds alongside his growing contact with the people and routines that make the role human.
