Sherlock Sammy

Sherlock Sammy (known as Enyclopedia Brown in the online version) is an imaginary character who appears in the book Sherlock Sammy Does it Again. He is a child detective who figures out mistakes in crimes and reveals them, making the criminal look like an idiot. He only appears because Greg says he is using Sammy's book for a book report. He even said he used the same exact book for five years straight.
