Sherlock Holmes receives a very rare visit from his brother Mycroft who works at the Foreign Office. He informed Sherlock that an international spy ring was at work and that in the past few months important secrets had leaked out, vital secrets that might bring the country to the verge of war. Mycroft said the Foreign Office suspected a beautiful and dangerous young lady in Paris and needed Sherlock and Holme’s help to catch her using Watson as the worm and Holmes as the hook.
