When Ed hires Joe as a driver, Lana persuades her husband to make him the traffic manager instead; she starts dropping by the office frequently. Joe continues to spurn her advances. One night, when Lana drives a drunk, unconscious Ed home from a party, she murders him on impulse, by leaving him in the garage with the car motor still idling. When the police investigate, it appears to be an accident. She later gives Joe a half-interest as a partner in the business in a subsequent attempt to attract him.
