Cinematography: Perhaps one of the most powerful camera shots in the entire series comes at the end of the final courtroom scene, as the camera, from the point of view of the judge, slowly and silently pans the entire room.

When Paul makes his second entrance into Perry’s office, there is a large plant left of the door. In later episodes there would be a table with painting above here. After consulting Perry, Nora Mae wears the stolen rings through the house to her room. Odd, indeed. DOD 06/01/18

The scene of Nora Mae carrying the tray of milk to Mrs. Gordon is reminiscent of Cary Grant carrying a glass on a tray in the 1946 film Suspicion, directed by Alfred Hitchcock. Submitted by H. Mason 10/23/14

"Arsenic Trioxide" is defined as "a white, tasteless, amorphous, slightly water-soluble, poisonous powder used chiefly in the manufacture of pigments and glass, as an insecticide, weed-killer, etc." [Webster's Encyc. Unabr. Dict.]. Mike Bedard 5.1.15

Testy-mony Perry's cross-examination of Dr. Meecham seemed remarkably pointed, with each seemingly trying to out-snark the other; it's always a small joy to find people who can go toe-to-toe with Perry's aggressive courtroom tactics, rather than be intimidated by them. Notcom 112421.
