Ellen Raskin's murder mystery The Westing Game, has a lot of characters. Raskin does an admirable job of balancing that character roster and allowing each of the characters to shine for relatively equal amounts of the book.
If you had to pick a protagonist, Turtle Wexler would be that character. She might be a reactionary tomboy who violently kicks other people, seems money-hungry, and often comes across as antagonistic, but readers are likely to find themselves rooting for her to win the Westing fortune. This is in part because we like rooting for underdogs. Readers feel that Turtle deserves it because of how her family has sort of cast her aside in favor of the more beautiful Angela. We also see that Turtle isn't only a shin-kicking brat. We see her willingness to take the blame for the bombing so her sister doesn't have to.
When the novel finally ends, readers see that Turtle has matured a great deal from the shin kicker that she used to be. A major part of this is the fact that the end of the book is years after the main events of the book. Turtle does indeed win the Westing Game, but she also wins a friend and mentor in Westing himself. She learns a great deal from him about how to run a company, treat people, make money, and pay it forward. With his death, Turtle inherits all of Westing's stock and becomes the director of the company. She also matures into an "attractive" woman and catches the eye of her future husband, Theo (whom she used to kick in the shins).
"Who's that attractive young woman talking with Flora
Baumbach?" Theo asked.
"Why, that's my daughter Turtle. She's really grown up,
hasn't she? Second year of college and she's only eighteen. Calls herself T. R. Wexler now."
T. R. Wexler was radiant. Earlier that day she had won her first chess game from the master.
The final moments of the book really show how Turtle has been changed. She is no longer looking out for herself. She is trying to pay it forward in the way that Westing did for her and many of the other characters. We are given the impression that Turtle is going to begin mentoring young Alice.
Veiled in black she hurried from the funeral services. It was Saturday and she had an important engagement. Angela brought her daughter, Alice, to the Wexler-Theodorakis mansion to spend Saturday afternoons with her aunt.
There she was, waiting for her in the library. Baba had
tied red ribbons in the one long pigtail down her back.
"Hi there, Alice," T. R. Wexler said. "Ready for a game of chess?"
