Plot Progression

1. A Statement With Consequences — Alan reports a robbery and is questioned by Mick Ross. The discovery of his relationship with Ron Miller turns the investigation into a criminal matter.
2. The Enigma Challenge — Alan enters government codebreaking work and is connected with Dilly Knox and Pat Green. Improving German machines intensify the pressure on the team.
3. Machines Against Complexity — The codebreakers decode German U-boat messages, establishing the importance of their work. Alan's mechanical-brain story expresses his unconventional approach to problems.
4. A Scientific Afterlife — Alan connects wartime work to the construction of a digital computer based on universal-machine ideas. He applies computation to patterns in plants and animals.
5. The Cost Of Genius — Drug treatment causes Alan shame and physical suffering. His final conversation with Pat places his scientific achievements beside lost emotional possibilities, injustice, and loneliness.
