Benjamin Brown (b.1992) is Charlie's youngest and best friend since they were five years old. Benjamin does not go to Bloor's Academy. He lives across Charlie in number twelve Filbert Street. He owns a dog named Runner Bean and his parents are private detectives. Although he isn't endowed and does not attend Bloor's, he does indeed play a fundamental part in the progression of the story, and is present at almost all of the meetings. He attends the same school as Lauren, Lysander's girlfriend. His parents take him to Hong Kong with them on a case of missing jewels. In the sixth book, his parents spy on the good endowed children at Bloor's for Ezekiel Bloor who offers them a great sum of money. This makes Charlie lose his trust for Benjamin, but collects it again when his parents give up on spying for the Bloors. Benjamin also gets mad at Charlie when Charlie always puts him danger. Charlie loses him multiple times.
