Looking for some insights or maybe even some suggestions of books that handle this well. I'm down to the last couple chapters of my MG draft, and I'm really wrestling with how a couple of 12YOs can realistically take down the bad guys (thieves) who think they are getting away with their thievery. They can't use brute force because they're kids, and I don't of course just want the cops to show up and take over with no effort on the part of my heroes. Obviously I need to tailor this to the particular setting of my book, but I'm trying to think of general models of how kids do this in books. The only thing I can think of is to have the adults counting on the situation from here on out being in their favor, only the kids possess a bit of knowledge the adults don't, and it thwarts the bad guys' plans/trips them up somehow.
Is it enough to have a kid manage to trip the security system somehow, to call for help? That way the adults who really can arrest these guys show up in time, but only because the kid alerted them. I'm not sure how climaxy that is, though.
The *main* issue of my story is the conflict between two particular characters, and the thieves who try to steal something important to both of these characters form the setting in which my characters have to resolve their differences. And I'm good on that part. But without being able to figure out the action resolution, I don't have a place to drop in that part of the ending.
Surely this has to be an issue that MG writers deal with quite often. How do you empower the kids and yet keep it believable? Ideas? Examples of books that have handled this well?
