In The Westing Game, what facts did you learn about the people associated with Sunset Towers?
We learn many things about the nieces and nephews who are the possible heirs to Sam Westing's fortune: Grace Windsor Wexler (who has two daughters -- Angela and Turtle) is a snobby housewife, Otis Amber is a sixty-two-year-old delivery "boy", Madame Hoo is an excitable woman married to a restauranteur, Theo and Chris Theodorakis are teenage boys, and Chris is a physically-challenged birdwatcher, Crow is a cleaning woman, D. Denton Deere is a young doctor, Flora Baumbach is a dressmaker, Sandy is a doorman, J. J. Ford is a judge, and Sydelle Pulaski a secretary. The most important thing we learn (in Chapter Six) is that these disparate characters (who didn't know anything of each other being possibly related to rich old Sam Westing) are all to compete in "The Westing Game" to see who becomes heir to the huge fortune Sam Westing left. It's a murder mystery, too, because Sam Westing's will accuses one of these people of murdering him.
These characters will compete in Sam's bizarre posthumous contest to prove who cared most about their old "Uncle Sam". The differences in the characters are meant to give an approximate cross-section of the people living in a small Wisconsin town.
