The Prince and the Pauper

This is an old book written by Mark Twain...
I have just started to read this book.
It is set in old London nad is about the English Prince and a begger who look exatly the same. The Prince takes his opptunity and "borrows the beggers clothes and runs away. Unbenowsed to the origional begger (Tom), he is now the Prince of England...
It is quite confusing so I will let you do the reading!
