Eleven-year-old Jeremy Wilderson teams up with his rival crime fighter to stop the stealing spree that’s wreaking havoc on Scottsville Middle School in this action-packed MAX novel.

Jeremy Wilderson is not a thief. In fact, he is his middle school’s one and only retrieval specialist. Confiscated cell phones, stolen lunch money—he’ll discretely retrieve it before the last bell rings. Business is good, and if it weren’t for the meddling of preteen private investigator Becca Mills, he’d be happier than a gym teacher on dodgeball day.

But a new job shatters his comfortable lifestyle. Now, thanks to Jeremy, the master key to the schools’ lockers is in the hands of an aspiring crime kingpin who doesn’t exactly have Jeremy’s strong moral character. Soon not even combination locks can protect the students’ textbooks and jackets. Retrieving the key is too big a job for one crime fighter, and only one person wants the key returned as much as Jeremy does: Becca Mills.

Lockers are being robbed, the teachers are looking for the culprit, and the only person Jeremy can turn to is the girl who most wants to see him in the principal’s office. Will Jeremy be able to trust Becca enough to get the key back in the right hands? Or could he end up in detention until the end of high school instead?
