This should be easy, but Google isnt helping. It was a children’s book from the 1980s. The nain character, Cass, couldn’t keep a secret and ended up embarrassing her family and friends. Her mom came up with plan- every day, three people would tell her things and she had to figure out which one was the secret. If she managed to successfully do it for a week, she’d get $5. Thank you!
