In November 2023, a significant cache of wartime documents, dubbed the “Bayley papers,” was auctioned in London, fetching nearly half a million U.S. dollars. This remarkable collection includes numerous sheets penned in **Turing**’s own hand, detailing his clandestine “Delilah” engineering project, active between 1943 and 1945. **Delilah** was **Turing**’s innovative portable voice-encryption system, aptly named after the biblical figure known for deception. The papers also contain material written by **Donald Bayley**, often in the form of notes taken during **Turing**’s discussions. It is thanks to **Bayley** that these invaluable historical documents survived, as he meticulously preserved them until his passing in 2020, 66 years after **Turing**’s death. The unearthing of these papers offers a fascinating glimpse into the lesser-known aspects of **Turing**'s wartime work, extending his legacy beyond the well-documented efforts at **Bletchley Park**.
