chunk: One night during a thunderstorm Jeff hears a woman scream "Don't!" and then the sound of breaking glass. Later he is awakened by thunder and observes Thorwald leaving his apartment. Thorwald makes repeated late-night trips carrying his sample case. The next morning Jeff notices that Thorwald's wife is gone, and then sees Thorwald cleaning a large knife and handsaw. Later, Thorwald ties a large trunk with heavy rope and has moving men haul it away. Jeff discusses all this with Lisa and with Stella.
  Jeff becomes convinced that Thorwald has murdered his wife. Jeff explains this to his friend Tom Doyle (Wendell Corey), a New York City Police detective, and asks him to do some research. Doyle finds nothing suspicious; apparently "Mrs. Thorwald" is upstate, and picked up the trunk herself.
