While on a sailing trip in the Baltic Sea, two young adventurers-turned-spies uncover a secret German plot to invade England. Widely recognized as the first modern spy thriller, this 1902 lone masterpiece by World War I Royal Navy officer Erskine Childers was written as a wake-up call to the British government to attend to its North Sea defenses. It accomplished that task and has been considered a classic of espionage literature ever since. Praised for its nautical action and richly authentic background as much as for its suspenseful spycraft, The Riddle of the Sands is the brilliant forerunner to the realism of Graham Greene and John le Carré.

Carruthers is rescued from a hot summer at a deserted Foreign Office in London, by an out-of-the-blue invitation to join an acquaintance, Davies, on his yacht in the Baltic. He arrives to find not only that he comprises the whole crew, but also that Davies needs his help in a spying mission with enormous stakes. The Riddle of the Sands, with its early warnings of the dangers of a German invasion by sea, created a sensation when it appeared in 1903. It is the forerunner of the spy novels of John le Carré and Graham Greene, and its detail and dry humor have made it a classic for sailors as well as for thriller addicts.PLEASE NOTE: When you purchase this title, the accompanying reference material will be available in your Library section along with the audio.
