Zudora, not knowing she's an heiress to a $20 million fortune, lives with her uncle, a mystic and detective, who covets her inheritance. She wants to marry John Storm but her uncle is against it. However, the uncle makes a bargain; if Zudora can solve the next twenty mysteries brought to him, she can marry as she chooses. Episodes 1,2 and 8, plus another unidentified chapter, survive. The rest is believed to be lost.
