Beatrix Potter story Kitty-in-Boots discovered after 100 years

A new story written by Beatrix Potter more than 100 years ago, featuring Peter Rabbit, is to be published for the first time.
The Tale of Kitty-in-Boots was rediscovered by publisher Jo Hanks after she found a reference to it in an out-of-print Potter biography.
Quentin Blake, best known for his work with Roald Dahl, has illustrated the story, to be published in September. BBC
