Benjamin Pratt and his friends Jill and Robert are determined to save their school from destruction! But just when it seems they've finally gotten the upper hand over that awful Janitor Lyman, they're caught completely off guard by his next move: Lyman has called in reinforcements, and suddenly Benjamin, Jill, and Robert find themselves dodging not one evil janitor, but two. That's right: Lyman's got himself a partner. And it quickly becomes clear that Wally, the new guy, is even more corrupt and menacing than Lyman.

Luckily, Ben's team has been growing, too. Plus, thanks to the latest safeguard, they also have a secret fund of millions of dollars. But all the money in Massachusetts isn't enough to stop Lyman and Wally, not when they've come this far, and not when they are just about to put the most harmful part of their plan into play. Could the next safeguard give the Keepers what they need--or has their battle to save the school already been sunk?
