"The Cat Who Would be King!"
Batman and Catwoman find themselves caught in a trap by Catman. Batman escapes from the trap, rescuing an unconscious Catwoman at the same time.
Later, it is revealed that Catwoman is suffering from an all-but-incurable disease, and only the herbs stolen by Catman can save her.
Batman and Catwoman team up to track down Catman. During their battle, Catman is engulfed in a steam geyser, and falls to his presumed death, taking the herbs with him. Catwoman collapses in despair, but later miraculously recovers -- thanks to a scrap of Catman's costume?
