Mr. Peterson is a “small, respectable” black man from Stockholm. Embroiled in Abe’s blunder with the police—acting as a key witness for him when he falsely accuses a black man of theft—Peterson fears for his life as several of the other men entangled in the affair seek revenge. He is an honest and hardworking man, proud of his shoe polish invention, and hopes that Dick and Abe will help him. Fairly unconcerned with Peterson’s fate, however, Dick next encounters him when Rosemary finds his dead body in her hotel room.
