Somewhere on the seabed of the Atlantic Ocean lie two casualties of the Second World War: a Japanese submarine, the I-52, and the liner SS Aurelia. Separated by almost a thousand miles and sunk more than a year apart, these two vessels have one thing in common - they were both carrying several tons of gold when they went down. In 1994, aboard the Russian research ship Akademik Keldysh, the treasure-seeking team Project Orca began a harrowing search for the sunken vessels and their riches. It was a mission that would take them nearly three-quarters of a mile deeper than the resting place of the Titanic, testing the human limits of deep-water exploration. In Three Miles Down, James Hamilton-Paterson, the ship's literary stowaway, captures the journey in intimate detail.
