The Big Mousetake

Poppy the Puptective is here to prevent an epic cake caper by a trio of mischievous mice in this third hilarious book in the graphic chapter book series perfect for fans of InvestiGators and Narwhal and Jelly.

Truffles the cat hates parties, especially birthday parties. So when a trio of mice calling themselves the Cheesy Crew crashes Truffles's human's birthday bash to steal the cheesecake, Truffles offers assistance. After all, no cake means no party, which means peace and quiet!

The would-be saboteurs should have known better than to cross the likes of Poppy the Great Puptective! Unlike Truffles, Poppy wants Sasha to have the best party ever, and the pup is on high alert! But with traps and distractions as far as she can see, will Poppy accidentally be party to the greatest caper in Cheesy Crew history?

About the Author
From the moment she was able to hold a pencil, Alina Tysoe was scribbling away and filling notebooks with doodles of dogs and comics about her family. Today, Alina is an illustrator, 2D animator, and author of What's Up Beanie: Acutely Relatable Comics, a collection based on her popular webcomic by the same name; the picture book Emi Isn't Scared of Monsters; and the graphic chapter book series The Great Puptective. She lives in Toronto with her husband, Mike, who makes regular appearances in her webcomic, and, infuriatingly, no dogs.
