Dark Charade

what happens

Jigen heads for the African republic of Borodias, with Lupin and company in pursuit, when he receives a letter from Sister Angelica. Angelica wants his help in rescuing Dr. Othello, head of the country's independence movement. Once a member of a noble Venetian family, she devoted herself to this land ever since Jigen left her eight years ago, when she looked to God for help. But the whole thing is the conspiracy of a major world power, which is controlling the situation from behind the scenes. Why are Othello's eyes blue?
