Key Discussion Points & Plot Breakdown

1. The Family Under Suspicion

• [02:12] Harvey Watkins confronts his secretary, Arthur Finlay, about $5,000 missing from the accounts:
  • Watkins: "Finlay, I've been going over your accounts. You're $5,000 short."
  • Threatens jail if repaid by 3:00 p.m.
• Watkins also accuses daughter Rosalind and her husband Bruce of stealing $20,000 in bearer bonds from his strongbox, threatening them similarly.
• [03:40] Suspicions extend to emotional conflict and lingering threats within the family.

2. The Death of Harvey Watkins

• [07:16] Minutes before 3:00 p.m., gas is smelled coming from Watkins' study; the door is bolted shut.
• The family and household scramble to open the window; Watkins is found dead, apparently asphyxiated.
  • Arthur Finlay: "Your father, Rosalind... He's slumped down before the door. I think he's dead." [08:00]
• Initial belief is suicide, but doubts begin:
  • Arthur Finlay (accusing): "I'll phone the police."
  • Jasmine Fisher: "Why the police, Finlay?"
  • Finlay: "Because I think you and Rosalind killed him, Bruce." [08:27]

3. Mr. Chameleon Arrives: The Investigation

• [08:48] Mr. Chameleon and Detective Dave Arnold arrive. Rosalind insists her father took his life, but Chameleon reveals they only investigate murders, not suicides.
• The door's lock is examined:
  • Mr. Chameleon: "If your father had locked himself in, Detective Arnold's key couldn't have entered the lock so easily." [10:11]
• The gas grate and chimney have been tampered with, and Watkins was also struck on the head—clear evidence of murder.

4. Unraveling Motives & Alibis

• [13:06] Mr. Chameleon accuses Rosalind and Bruce, referencing a letter the police received from the murdered man:
  • Chameleon: "It seems I have a pretty clear murder case against you and your husband."
• [14:02] Jasmine Fisher arrives to defend Rosalind and Bruce, providing an alibi: Watkins found the “missing” bonds in a drawer before his death.
  • Jasmine Fisher: "But they didn't steal any bonds... Watkins later found the bonds in one of his desk drawers." [15:08]

5. The Secretary Under the Lens

• [18:53] Chameleon and Arnold confront Arthur Finlay, who claims a friend lent him the missing $5,000 so he could pay back Watkins.
  • Mr. Chameleon: "Are you trying to make us believe that $5,000 cash you've got there was lent you by a friend...?" [19:03]
• Finlay's story is shaky, but his books appear in order, suggesting he might be innocent.

6. The Detective's Trap: The True Culprit Emerges

• [22:15] Mr. Chameleon plans to re-enter the house disguised as gas fitter Al Hicks to provoke the suspects.

7. The Solution & Confession
