This is a pretty decent addition to the Little Miss series. In it, Little Miss Trouble is....well, she's not so much a troublemaker as she is a devious little bitch. She lies just because. And she has a hate boner for Mr. Small for some reason. She keeps telling other people that Mr. Small said some shit about them, and instead of acting like an adult they just punch him in the goddamn eye while Little Miss Trouble presumably jizzes somewhere in the bushes. After this happens a few times Mr. Small decides to take the doctor's advice (and really, it's pretty shitty advice for a doctor to be giving) and goes around telling people that Little Miss Trouble said some bad things about them. This is morally okay though, for some reason. Anyway, when the other people(?) find out about this, they tickle her instead of punching her in the eye because this book is sexist.
In the end, everyone learns a valuable lesson that lying to get other people in trouble is hilarious, as long as they don't find out it was you. So as long as you're name is not like, oh say Little Miss Trouble or Mr. Lying Dickhead or something, it should be easy to be play innocent should anyone ask.
