Five Go Adventuring Again

Five go adventuring Again is the second book in the Famous Five series by Enid Blyton

George Kirrin and Anne Barnard have gone to a boarding school together. They find out that in the holidays, they will have a tutor. The girls and Timothy join up with Anne's brothers and go to Kirrin cottage, where Georges parents reside. When they get there, the Five find a secret map written in latin, and ask Mr. Roland to translate it. George is against the idea, because Timothy refuses to shake hands with him so George finds him suspicious. Tensions rise and Tim is banned from being in the house and has to stay in his kennel. George and the other three argue about Mr. Roland and she threatens to run away. George worries about Tim, and one night, sneaks into her fathers office with her dog and sleeps on the rug with him. In the morning, Uncle Quentin finds that some of his important scientific papers are missing and George admits she had been in here but didn't take the papers. I'm not going to spoil the ending so you will need to read the book or a Wikipedia page to find out what happens.
