Lisa Clark was the skeptical daughter of Ethan Clark.
Lisa disliked her father's trust in Nostromos, who gained credibility by prediciting danger and avoiding bad investments. She was not swayed by Nostromos' predictions that came true, and to Bruce Wayne she confided that she thought there might have been malice involved, or rather Nostromos was acting out his own forecastings .
Lisa had hoped to find an ally in Bruce, but after an "accident" befell Bruce, true to Nostromos' "predictions", she thought she had lost him too. She set up her own plans to bring the charlatan down: on the night of Bruce's formal initiation, Lisa snuck into the building. She found out she had been right when she eavesdropped on Nostromos' assistant Lucas, who then captured her.
She was tied to one of the planets of the orrery. Batman got her out just before the rings of Saturn cut up Mars. After Nostromos was arrested, she was relieved her father, and Bruce, got back to their senses.
