The Sherlock Society goes undercover in the Miami street art scene to find an anonymous graffiti artist in this third book in the hilarious, New York Times bestselling Sherlock Society middle grade series from Edgar Award-winning author James Ponti!

The Sherlock Society's latest case is tracking down stealth graffiti artist Funky Munky--well-known for their artistic statements calling out local politicians--on behalf of a developer who wants them to create a mural for a new hotel. Their investigation leads Alex, Zoe, Lina, and Yadi deep into the very colorful south Florida art scene.

But finding someone who doesn't want to be found is challenging, and it doesn't help that Miami Art Week is coming up, bringing lots of attention--and lots of new artists--to the area. The Sherlock Society's best bet is an elaborate sting operation, which involves them picking up spray cans themselves. Can they trap their quarry without exposing themselves?
