The Picts and the Martyrs: or Not Welcome At All by Arthur Ransome
The poor old Amazons become Martyrs and the Ds Picts living in the woods, in Arthur Ransome's 11th adventure. The Ds can't wait to go and stay with Nancy and Peggy in the Lake District during the summer holidays. But when the Amazons' dreadful Great Aunt invites herself to stay too, the summer is threatened with dullness. Staying indoors and reading poetry is not what the Amazons had in mind. To save the Ds from the same fate they organise for them to stay in the Dogs' Home, a tumble-down hut in the woods. As long as no one discovers they're there they can sail all summer long.
