Book Hero Magic formatted this description to make it easier to read. While it's new and still learning, it may not be perfect - your feedback is welcome! Description
From bestselling children's author and TV broadcaster, Dermot O'Leary, comes an action-packed new adventure from Toto the Ninja Cat — the crown jewels are missing and the thief is on the run! Perfect for fans of The Aristocats, The Secret Life of Pets, and Atticus Claw Breaks the Law.

Toto and her friends are due to be looking after the French ambassador on a day of sightseeing, finishing at the Tower of London to see the animal world's crown jewels: a sacred diamond cat collar.

But when they arrive, the collar has disappeared — and what's worse, it looks like Toto is responsible! Toto is almost arrested, but she escapes to try and get to the bottom of the mystery and clear her name.

She and her friends will have to follow some strange clues that will take them to a secret bookshop, Buckingham Palace, and the rats' underground city in the sewers... Can they defeat an unexpected villain and bring the thief to justice?

Ideal for reading aloud or for children to curl up with and read alone, the story features brilliant black and white illustrations throughout by Nick East. With gentle themes of friendship, inclusivity, and winning in the face of adversity, this is a hilarious must-read for all animal-loving kids!

Dermot says: 'The idea for Toto first came to me when my wife and I rescued two stray cats from an olive grove in Italy. One of them, Toto, has been blind from birth, but we quickly realised she had ninja-like reactions. Like a lot of cat owners (or cat servants), we like to imagine our pets having secret lives when we're out or asleep. So before I knew it I was writing about Toto and her brother Silver's nocturnal adventures around London. I really hope that children who pick it up enjoy reading the adventures of our little Italian underdog (cat).'

Have you seen Toto's other adventures? The Great Snake Escape, The Incredible Cheese Heist, The Superstar Catastrophe and The Legend of the Wildcat are out now, and make perfect gifts for young readers.

For more animal adventures, discover Wings of Glory. Can one tiny bird help to win a world war? A funny action-adventure story with a feathery twist, from the bestselling children's author of Toto the Ninja Cat, Dermot O'Leary, with glorious illustrations throughout by Claire Powell.
