M. Mabeuf was the Churchwarden, and Marius' best friend. He told Marius the truth about his father caring for Marius. He went on walks, with at least 1 book, and usually came back with two. When Valjean's purse was stolen and thrown by Éponine, it was Mabeuf who found the purse, which helped pay for bills. He was the first to die at the barricades.
