Biography
Henry Claridge was a millionaire who lived in Gotham City. The Joker selected him to be his first victim. He issued a radio broadcast declaring that he would murder Claridge at the stroke of midnight and steal his fabled prized diamond. The Gotham City Police Department gave him in-house protection, but as the clock struck midnight, Claridge fell over dead - a ghoulish grin etched across his face - the telltale sign of the Joker's infamous venom.
