A beautiful woman has had too much to drink. In an alluring red dress, she staggers across a busy street, apparently in danger of being hit, while the surrounding crowd jockeys for a better view. No one wants to miss something which might make the evening news. In a window above the scene, a lone man watches the crowd, not her. He knows she is not in danger. He’s looking for someone moving away from the disturbance, not toward it. There’s an enemy agent nearby, and he wants to pop him out. When he locates the person heading away from the woman, he’ll know he’s found his spy.
