Hello, Gerald. I hope this isnt too weird for you--a letter from beyond the grave! By now you are my heir and worth a good deal of money. I hope you dont mind. I expect youve figured out that I was murdered. I would like you to find out who did it. Gerald Wilkins had only been hoping for a ski holiday, but plans change when a great aunt hes never met leaves him her entire estate worth twenty billion pounds! Whisked by his parents to London, England, Gerald is given a letter and told not to open it until after the funeral. Now hes got a mystery to solve. With the help of his new friends, Sam and Ruby Valentine, Gerald follows the clues into secret passageways, a musty jumbled bookshop, an ancient crypt and a colossal cavern where the secret of a priceless treasure lies protected by deadly booby traps.
