Owner and co-founder of "Justice and Dixon: Private Investigations". "Black Jack" Justice is a grizzled, hard-boiled private detective and one of the two protagonists of the series, along with his partner, Trixie Dixon. Little is known about his childhood; he's one of seven children (four brothers and two sisters). Not much information is given about his parents. His father obviously shared some of his viewpoints ("I remembered what Jack's father had told him; If you're going to bet angry, make sure you cheat." Epi.13).
