Hydra, an underground crime organization of American and British agents, has been disrupting the world economy with its activity over the past several months. Via an informer you had planted among the Hydra management, you have learned of a gigantic counterfeiting scheme that the organization is about to perform. You were about to thwart their plans, and in the process obtain enough information and evidence to crack the ring, but without warning your informer has vanished. You are not sure how Hydra became wise to you, but you suspect there is a leak in your agency. Your object is to investigate the disappearance of your informer and hopefully find him while at the same time continuing your efforts to foil Hydra's counterfeiting scheme.
