The protagonist in Truman Capote'sIn Cold Bloodis certainly Richard Eugene Hickock. He is the person who conceives the idea of traveling to the Clutter ranch and murdering the entire family. He believes that Herbert Clutter has $10,000 in cash in a wall safe in his office. Perry Smith, Dick's partner, is neither the protagonist nor the antagonist; he just goes along with Dick's plan and continues to let him be the leader right up to the time that they are arrested. There were many people involved in trying to solve the murders, but Capote obviously felt it would be advisable for dramatic purposes to focus on one lawman. He uses Alvin Dewey as that antagonist. The protagonist's struggle is to get money and stay out of prison. He also has to deal with a hypersensitive partner in crime who is sometimes hard to control.
