The Spy is a tale about counterespionage set during the Revolutionary War, with main character Harvey Birch, British loyalist who is in fact a George Washington's spy. The plot ranges back and forth over the neutral ground between the Continental and British armies with great haste and sweep. The action takes place so near to great events and the characters are all invested with something of the dusky light of heroes, while George Washington moves among them like an unsuspected god. This was the earliest American novel to win wide and permanent fame and may be said to have begun the type of romance which dominated U.S. fiction for 30 years. James Fenimore Cooper (1789–1851) was a prolific and popular American writer of the early 19th century. His historical romances of frontier and Indian life in the early American days created a unique form of American literature. Before embarking on his career as a writer, Cooper served in the U.S. Navy as a Midshipman, which greatly influenced many of his novels and other writings. The novel that launched his career was The Spy, he also wrote numerous sea stories, and his best-known works are five historical novels of the frontier period known as the Leatherstocking Tales. Among his most famous works is the Romantic novel The Last of the Mohicans, often regarded as his masterpiece.
