Bruce Wayne approaches Henri Ducard for training in Paris, during his early days traveling the world. Ducard, a knowledgeable detective with excellent man hunting skills, imparted much of his knowledge to the young, keen Bruce. Later in the series, it is revealed that Ducard is largely amoral, working for criminals as often as he does the law. He deduces Batman's secret identity, but keeps it to himself, thinking as he leaves that Batman continues to exist because true criminals realize that he distracts the people from the greater crimes by his public battle against lesser crimes.
