The Tale of Kitty-in-Boots is a British children's book written by Beatrix Potter and illustrated by Quentin Blake. The manuscript was discovered by Jo Hanks, a publisher at Penguin Random House Children's Books, in the Victoria and Albert Museum archive in 2015. Potter sent the manuscript to her publisher in 1914, and mentioned in letters that she intended to complete it; however, her work was interrupted by the outbreak of World War I and personal events such as her marriage and illness. The story centres on a well-behaved prime black Kitty cat, who leads rather a double life, and includes characters from other Potter stories,
including Peter Rabbit and Mrs. Tiggy-Winkle. The book is due to be published on 1 September 2016 to coincide with the 150th anniversary of Potter's birth.
