Chesterton’s Father Brown mysteries: “The Eye of Apollo” and “The Invisible Man.” The show captures the golden age of radio and its detective storytelling, delivering a blend of intrigue, wit, and moral questioning. In these dramatized tales, the quietly insightful Father Brown joins with former criminal and private detective Flambeau to unravel seemingly impossible crimes—illuminating human nature and the unseen motives beneath the surface.

The Eye of Apollo (00:01–26:58)

Main Theme

An apparent accident in a modern office building leads Father Brown to uncover the dark interplay between faith, blindness—both physical and spiritual—and deadly ambition.

Key Discussion Points and Plot Structure

1. Introduction to the Setting (01:29–04:23)

• Father Brown is contacted by Inspector Bagshaw regarding Flambeau and a mysterious new religion led by Kalon, the "sun priest."
• Father Brown visits the new office block, encountering the building’s eccentric residents and elevator system.

2. The Stacy Sisters and Modernity (06:04–11:13)

• Pauline and Joan Stacy run a typewriting bureau; Pauline is fixated on health, efficiency, and eschewing spectacles for "scientific" reasons.
• Discussion about human weakness, pride, and technology's impact:
  • “True scientific invention is the force of man. And woman too, she says. But these nasty props and potions the doctors sell, they are the marks of our slavery.” — Flambeau relaying Pauline Stacy’s view (09:37).

3. Flambeau’s Reformation (11:13–13:20)

• Flambeau discusses his attempt to go straight as a private detective.
• Notable moment:
  • “I am human. I am frail. For all my size and strength, for many years the life of the criminal is the only life I know. Now I try to change. Pray for me.” — Flambeau (12:10).

4. The Fatal Incident (13:20–16:08)

• Pauline routinely joins Kalon for daily sun worship on the balcony.
• A sudden tragedy: Pauline falls to her death down the elevator shaft.
• Sounds of a crash and crowd panic; questions about whether it was an accident or murder.

5. The Investigation: Who Had Motive? (16:08–21:12)

• Suspicion falls on Kalon, Joan Stacy, Flambeau, and even Father Brown.
• The will: Pauline had written one in favor of Kalon and the Church of Aten right before her death, but did not sign it.
• Kalon offers polemics on innocence vs. guilt; Father Brown reflects:
  • “Is anyone without sin? There have, I feel, been sins committed here... but I doubt whether they could lead to a conviction in a court of law. I confess, I am defeated.” (20:54)

6. The Revelation: A Case of Sight and Blindness (22:01–24:10)

• Father Brown deduces Pauline’s “accident” was due to her near-blindness and refusal to wear spectacles, worsened by staring at the sun.
• The elevator was called above her, leaving the shaft empty.
• Kalon's possible involvement: he knew about her impairment and may have withdrawn the lift at a crucial moment.

7. Final Insights: Human Guilt (25:41–26:29)

• Joan Stacy is not entirely guiltless: she tried to prevent the will’s signing by emptying all fountain pens, hoping blindness would cause Pauline not to notice.
• Quote:
  • “Ah, but, Inspector, she is not wholly without guilt. One was to guess that her sister was in danger and to come down to the public house... the other was more deceit... She emptied all the fountain pens into the waste paper bin.” — Father Brown (25:41)

8. Denouement (26:29–26:58)

• Father Brown reveals he sensed Kalon’s guilt due to his unnatural calm at the moment of the death.
• Justice, in the legal sense, is elusive, but spiritual culpability is revealed.

Notable Quotes and Moments

• “We are taught that principles, motives are what we should judge a man on.” — Father Brown (17:39)
• “Let Cain pass, for he belongs to God.” — Father Brown, referencing Kalon after the confrontation (24:54)

The Invisible Man (29:05–55:38)

Main Theme

A locked-room murder mystery explores not just how a killer can evade sight, but how societal “invisibility” helps crime flourish. Father Brown scrutinizes the literal and figurative "blind spots" of the privileged.

Key Discussion Points and Plot Structure

1. Romantic Subplot and Arrival of Threats (29:30–37:32)

• Laura, a coffee shop worker, is courted by John Turnbull Angus.
• Laura’s past: she once refused two suitors who have now returned—Isadore Smythe (inventor, prospering) and James Welkin (nondescript and enigmatic).
• Ominous threats from Welkin, including a note:
  • “If you marry him, he will die.” — Anonymous, later identified as Welkin (37:45)

2. The Threat Increases (37:32–40:06)

• Smythe reveals repeated threats and intimidation; Welkin’s presence is felt, but never seen.
• Father Brown recommends Flambeau as a detective; the group resolves to protect Smythe.

3. The Set-Up: Security and Surveillance (40:25–45:16)

• Smythe’s home is fortified: combination locks, alarms, cleaning woman on watch, hall porter, chestnut vendor, and even a policeman alerted.

4. The Locked-Room Puzzle Unfolds (46:05–49:43)

• Despite all precautions and witnesses, Smythe is killed.
• Mysterious wet footprints (coming in and out) suggest an unknown perpetrator.
• The body is missing, but traces of blood and disturbance are found.

5. The Solution: Social Invisibility (49:43–54:05)

• Father Brown’s insight: the murderer, “the invisible man,” was visible all along, but overlooked because of his role.
• The killer was James Welkin, disguised as a postman—even carrying the body out unnoticed.
• “Rich people never notice the presence of servants. They take them for granted. To them they are invisible.” — Father Brown (51:33)

6. Language and Perception (52:22–54:05)

• Father Brown explains how people only answer what they think you mean, leading to crucial misunderstandings in eyewitness testimony.

7. Epilogue: Justice and Wealth (54:58–55:38)

• Laura discards Smythe’s will, rejecting sudden wealth:
  • “She was determined that the man she would marry would... carve his own way in the world. What a challenge for young Mr. Angus.” — Father Brown (55:13)

Notable Quotes and Memorable Moments

Episode Tone and Style

The dialogue is witty and brisk, with Father Brown's humility and quiet wisdom often contrasted against Flambeau's flamboyance and Inspector Bagshaw's directness. The stories blend humor, subtle moral lessons, and social observation. Father Brown’s methods emphasize human psychology over technical clues, and his deductions often challenge the audience’s—and his companions’—assumptions about guilt and innocence.

Conclusion

This double-feature showcases the enduring appeal of the Father Brown mysteries—where logic, empathy, and attention to the overlooked point the way to truth. Both "The Eye of Apollo" and "The Invisible Man" unravel puzzles of sight and perception—showing that blindness is not just a physical condition, but a metaphor for prejudice and inattention.

“I knew Kalon had done it before we came into the front door. Human nature. In the middle of Kalon's prayers, there was a crash, a scream... but Kalon continued, unperturbed. He did not start or even look down. He clearly expected something of the kind.” — Father Brown (26:29)
