Doug Hoo
Doug Hoo is the son of Mr. Hoo and the stepson of Madame Hoo. His father married her after his biological mother died. They live in apartment 4C of Sunset Towers. Doug is a high school senior and a track star. He spends a lot of his time practicing for his running competitions. However, his father doesn't like this. He thinks that Doug wastes his time running and he always tells his son to "Go study." For the reading of the will, he writes "first in all-state high-school mile run" as his position. Doug's partner is Theo Theodorakis. Their clues are HIS, N, ON, TO, THEE, FOR. After a while, Theo realizes that the clues form a chemical formula with four left over letters that spell out Otis. He believes this means Otis Amber is the murderer. Theo tells Doug to follow Otis wherever he goes in order to spy on him. Doug gets a lot of running practice done while doing this.
