Poseidon: China's Secret Salvage of Britain's Lost Submarine

Poseidon is a drama which opens with the death of the protagonist. HMS Poseidon was a British submarine which sank after a collision with a Chinese freighter a few nautical miles off the coast of Shandong in 1931. Twenty-one of the crew of 56 were lost, two after escaping from the sunken wreck. Steven Schwankert is a semi-professional scuba diver based in Beijing who learned of the sinking while searching for dive sites in Chinese waters and was fascinated by the little-known story of the sinking and its aftermath. Poseidon tells the story of his research.
