One of the few episodes where Perry uses the bust of Voltaire in his office as a hat rack.
When Mrs. Kirby offers Perry a meal at her restaurant, Perry slyly smiles and says he's on a diet. This is a bit of an inside joke in the script, as Raymond Burr had gone on a crash diet to lose weight in order to get the lead role.
Shepperd Strudwick (Dr. Morris) also played the doctor who kills Willie Stark in All the King's Men (1949).
Lt. Tragg is able to recite Perry's office number from memory.
Mrs. Kirby's first name is Angela.
