Martin Kirchoff, a man that Diana Reid prosecuted onto death row, and who vowed vengeance, escapes, but she doesn't hear about it. Upon receiving a note signed, "Your Secret Admirer," asking to meet her at what was in fact the scene of Kirchoff's crime, Diana suspects it to be from Hayashi. A call to Paul tells her that Hay is "gone for the evening. Said he had some business to take care of," and she tells Paul to inform him that she'll "keep our date at the park." Soon thereafter Kato walks in and, after Paul delivers Diana's message, replies that he has no idea what she was talking about. At this point a TV newscast announces Kirchoff's escape, the pair put two and two together, and hurriedly change into their disguises. The Green Hornet and his associate arrive at the scene just in time. However, Kirchoff has made good use of the prison gym and surprisingly throws Kato into the Hornet, taking them both out. Nevertheless, the fight has distracted Kirchoff enough to allow Diana to run, but not far enough. As he catches up to her, she pushes Kirchoff into a high voltage device, killing him.
