Down with the Dirty Danes! 

An hilarious story, told in letter form, about King Alfred – he who burnt the cakes, and his battles with the Vikings.Berwin, son of Egfrith, writes to Wulfric, son of Elred using his miraculous new talent of reading and writing. Berry’s spellings leave a lot to be desired and in his hilarious letters he tells a tale of mixups and mayhem when King Alfred hides in his family’s cottage but is mistaken for a Dirty Dane – their word for the Vikings. A completely new perspective on why and how those cakes got burned!Fast and very, very funny from the prize-winning author of The Demon Headmaster and other books.
