Three Miles Down: A Firsthand Account of Deep Sea Exploration and a Hunt for Sunken World War II Treasure by James Hamilton?Paterson (1998; reprinted 2000) recounts the author’s participation in Project Orca, an expedition to locate and recover gold from two World War II wrecks—the Japanese submarine I?52 and the British liner SS Aurelia. The book blends adventure narrative with technical detail, describing life aboard the Russian research vessel Akademik Mstislav Keldysh, the challenges of deep?sea diving, and the human dynamics of international collaboration three miles beneath the South Atlantic.
