The Magic Riddle.
Cindy, short for Cinderella, lives with her widowed stepmother and two stepsisters, Bertha and Ertha. Cindy is forced to do all of the housework and is effectively a servant. The widow hates Cindy because when her late Grandfather died, he hid his will which the widow knows passes all the family inheritance to Cindy. The widow purposely keeps Cindy busy so that she won't find the will, giving the widow time to find it first. The widow is also planning to marry her favorite daughter, Bertha, to a handsome young man named Phillipe, though he is smitten with Cindy.
