Book
Horse Under Water
A British agent is drawn into a search for a German U-boat sunk off the Portuguese coast during the Second World War. Its cargo may connect wartime Nazi operations with a modern criminal and intelligence network, and the attempt to recover the wreck attracts divers, smugglers and officials whose motives are difficult to separate.
The investigation shifts between present-day surveillance and secrets left beneath the Atlantic. Deighton uses the physical danger of underwater exploration to expose a larger struggle over documents, money and political leverage, showing how the unfinished business of the war continued to feed Cold War espionage long after the fighting ended.
