A Mission Assigned

The Assignment
Its purpose
The hosts send the operative to halt human progress after Andrew Martin’s mathematical breakthrough. His orders include destroying evidence and eliminating people who know the result.
Its cost
He accepts the task as logical protection for the wider universe, without yet understanding the people whose lives it will endanger.
Arrival on the Motorway

A Violent Arrival
Disorientation
The operative appears naked on an English motorway, overwhelmed by darkness, weather, gravity, unfamiliar anatomy, and the roar of traffic. A car strikes him before he can understand the road.
First contact
He recovers, escapes an ambulance, and encounters a world that feels physically hostile and socially unreadable.
The First Cover Story

Learning to Pass
Arrest and examination
After leaving a petrol station, he is arrested for public indecency and subjected to questioning and psychiatric assessment. His ignorance is mistaken for mental illness.
A provisional identity
He claims to be Andrew Martin and learns that clothes and familiar behavior are necessary to move through human society without attracting further scrutiny.
Proof and First Killing

Evidence Under Threat
Erasing the discovery
At Fitzwilliam College, he finds Andrew Martin’s proof of the Riemann hypothesis and deletes the file and related records. He learns that the discovery may accelerate human technology dramatically.
Silencing a witness
He kills Daniel Russell by manipulating his heart, then watches Tabitha Russell grieve. The human cost begins to unsettle the logic that had made the mission seem clean.
The Mission Reversed

Choosing the Humans
Defiance
After saving Gulliver Martin from a suicide attempt, the operative refuses to kill him and Isobel. He relinquishes his gifts rather than return to painless immortality.
A new purpose
When a replacement arrives, he fights beside Gulliver Martin to stop the mission. Years later, he returns to Cambridge, recognizing home not as a planet but as the people he can love.
