About the Author

Kjartan Poskitt

Agatha Parrot says: 'So far I've written out most of the words in my spelling book. I've also filled about 12 numeracy books, 9 literacy books and once did a project about how the sun makes plants grow which Miss Barking gave me a gold star for. This book took me AGES though! Well I didn't exactly write it, I just talked and the old man typed it out, but it took almost the whole afternoon. It would have been quicker if he hadn't kept stopping to check if he'd got any emails, but he never had. (What a loser!)'

Kjartan Poskitt is the well-loved author of many hilarious books for children including Agatha Parrot and the Murderous Maths series, translated into over 30 languages. With a background in children’s television, he is a tireless and brilliant performer.
