Does the old dry cleaning ticket Gerald found amongst Green's belongings hold the key? And how does an invitation to join the secretive Billionaire's Club land Gerald in so much trouble? Join Gerald and his friends in the USA, the Czech Republic and a tiny island in Sweden for a new thrilling adventure. After all, with all that money, there's got to be more to the story.
