Sherlock Holmes and the Mystery of the German Spy

EXPOSITION: Sherlock Holmes and Dr. Watson are a mystery solving duo, living in London, England, 1917. The U.S. has just entered WWI.
INCITING INCIDENT: Sherlock receives an urgent letter from the U.S. government saying that two representatives will arrive at his house, the following day at noon, and they require complete privacy.
RISING ACTION: The two U.S. official representatives explain that a German spy has stolen important documents from the pentagon, regarding vital war plans against Germany. They need him to track down the spy, whom they believe will attend a government function in London, one week from then.
CLIMAX: Sherlock and Watson are at the government function, trying to determine who the German spy is. Sherlock uses his classic method of closely monitoring people's idiosyncrasies, and details regarding their appearance. Unfortunately the spy has been trained very well, so everything from his appearance to his manners and speech, makes him indistinguishable from an Englishman. Sherlock poses as a server, and "accidentally" spills hot soup on the man he believes to be the spy, who instinctively swears in German.
FALLING ACTION: The spy has revealed himself, and is arrested and forced to hand over the stolen documents about the U.S.' war plans.
RESOLUTION: Sherlock Holmes and Dr. Watson have successfully solved the mystery of the German spy.
