Sarah's detective skills are shown during her attempts with Gordon to catch Batman, by guessing (correctly) that he is Bruce Wayne by virtue of his history and the money needed for Batman's arsenal. She and Gordon, who was married at the time, start a brief affair, but a corrupt Commissioner Gillian B. Loeb attempts to blackmail them; Gordon ends the affair and confesses his actions to his wife Barbara. Sarah leaves Gotham City for New York City soon afterwards.^[37]

Sarah returns in Batman #458 (January 1991), where it is explained that she had married a New York cop who was killed during a drug bust.
