Charles Augustus Milverton (チャールズ・オーガスタス・ミルヴァートン Chyāruzu Ōgasutasu Mirubāton) is a media mogul who seeks to stir up conflict in London, making him an enemy of both William James Moriarty & Sherlock Holmes.
Milverton is a man of reasonable height with chin-length, curly white hair and piercing yellow eyes. In the musical his hair is dark gray, bordering on black, instead of white.
He wears a pair of chain-less pince-nez glasses with round lenses and is usually seen wearing a darkly colored three-piece suit, accompanied by a black fedora.
Evil to the point where Sherlock considers him one of his greatest foes. He does not care for others only himself.
Milverton is based off the character of the same name from Arthur Conan Doyle's Sherlock Holmes series, who in turn was based off a real-life criminal, Charles Augustus Howell, known for blackmailing artists.
