When someone steals Mr. Dozen's muffin recipe, readers join superspy Ethan Doodle to solve the crime.

First, assemble your spy kit! Draw yourself goggles and a fake mustache. Now trick out your spy bike with a rocket booster, lasers, and wings! WAIT! Which door did the suspect go through? Each one takes you to a different page....

Readers can sketch, doodle, and draw their way through the story with different options for arriving at the conclusion. And when they're finished, it's easy to go back to the beginning and create a whole new spy mission!

From author Andrew Judge and his brother Chris Judge, illustrator of the Danger Is Everywhere series, comes a brand-new hybrid chapter book series full of fun prompts and silly jokes that are sure to entertain kids and have them reaching for the next book!
