What did Turtle do with her clues?

In chapter 7 of The Westing Game, the game is described. The sixteen players are divided into teams of two. Each partnership receives a unique set of clues. The characters begin to strategize, as they realize that not only do they need the clues given to them, they will also need the clues they were not given in order to put it all together.
It seems that part of the game will be finding out what clues were given to the others. Grace thinks she will be able to get the clues from others, such as her daughters. Flora picks up a clue that Chris dropped, and she sees one word. Sydelle tells Angela that, instead of reading their clues right away, they should observe the others as they read.
Turtle asks her partner, Flora, to memorize the clues. Once they both have the words memorized, Turtle chews and swallows the clues in order to get rid of them. Now no one else will read their clues.
