intro: |
|
||
**Hawthorn Park, Buckinghamshire. 14 January 1943.**
|
||
|
||
Behind the fences, hundreds of people break enemy codes in freezing wooden huts. Nobody outside knows.
|
||
|
||
At 03:00, **Eleanor Finch**, the best codebreaker in Hut 7, is found dead at her desk.
|
||
The stove is out. The air smells wrong. On her desk, a typed note accuses a colleague of being a spy.
|
||
|
||
Eleanor was working on something alone. Someone made sure she never finished.
