El código Twyford

Edith Twyford was a world famous children's book writer, but now her only legacy is the rumored existence of the Twyford code: a series of clues hidden in her books that lead... to what? Nobody knows, but that is not why speculation has ceased. Steve Smith can connect almost all the misfortunes of his life with Edith Twyford. When he was a boy, he found one of her novels full of strange symbols written in the margin. He showed it to her teacher, Miss Bush, who immediately thought it contained the key to the code. Within a few weeks, Miss Bush disappeared, and Steve doesn't know if she's dead or alive...or whether or not she figured out the mystery of the code. Now Steve is determined to find out. But the Twyford code hides secrets and some would do anything to possess them, and Steve isn't the only one on his trail. The race to solve the mystery of the century has begun. Can you get there first?
