The Travelers Detective Club San Francisco Bay Area

Jeremy and Devon find themselves facing off against a familiar foe in The Travelers Detective Club San Francisco Bay Area. The magical hat that slipped through their fingers in Paris is now in Oakland, CA, not far from Jeremy's house. But how to get it? And how to keep landmarks and symbols of the city of San Francisco safe from a man who wants to cause world-wide financial chaos, or perhaps just have the world's most awesome train set?
Devon and Jeremy, together with Thing and Birdbrain, magical creatures who continue to develop new powers, traverse the Bay in an attempt to stay one step ahead of their adversary. Joining them is a new detective who inherits a magic buddy with a personality conflict. Can the three detectives chase down the magical hat before the Golden Gate Bridge disappears? Will they capture the hat and destroy it, or will it slip from their hands again, causing worldwide mayhem? And are there any long-term consequences to being shrunk to the size of a miniature action figure?
