This wasn't bad, exactly, but it wasn't as good as the last few I've read. This is largely down to the fact that it's pretty repetitive - it feels as if the bulk of the story is the kids going back to the same amusement park and going on the same rides over and over. And as much as I appreciate the consistency of "you meddling kids!" in children's mystery series - no villain wants to be out-thought by a bunch of pre-teens - having the villain here try to target the kids in the middle of the amusement park, where everyone could see their villainous actions and come running to help... Let's just say it wasn't well thought out on their part.

I mean, Benny's not even a pre-teen. He's six. And I'm pretty sure even he's got more brains than that.
