Summary By: Choice Classic Radio

Overview

This episode of The New Adventures of Sherlock Holmes finds the great detective, with Dr. Watson and guest French detective Monsieur Levia, drawn into a mystery by a ciphered message in the Agony Column of the Times. What at first appears to be a practical joke leads to a tense investigation of impersonation and attempted murder, centered around the reclusive Baconian scholar, Mr. Quilter, at a country house called The Elms in Penge.

At its heart, this is a classic Holmes tale of clever code-breaking, family intrigue, and rapid logical deductions, as Holmes finds himself racing against time to save a life—and reveal the real danger hiding beneath an innocent inquiry.

Key Discussion Points, Plot Breakdowns & Insights

1. Opening and Setup

• Setting: Dr. Watson recounts the tale to host Harry Bartell, recalling how a French detective, Monsieur Levia, visited Sherlock Holmes in 1889 to discuss translating Holmes’s monographs.
• Banter: The story opens with friendly ribbing between Holmes, Watson, and Levia about the superiority (or lack thereof) of English criminals vs. French ones.
  • [04:53-05:09] Levia: “I will yield to no one in my admiration of your knowledge and skill… But, what can happen to interest you in this land of gray frogs, boiled potatoes and pots of tea?”
  • [05:34] Watson: “You’re not very flattering.”

2. The Agony Column and Codebreaking

• The trio spots a strange, badly-printed ad in the paper: "Will any gentleman interested in discussing cryptography and cipher writing please communicate with box XQL696..."
• Holmes quickly realizes the inconsistent use of capitals and lowercase letters is a Baconian cipher—a code using typesetting to represent letters.
  • [07:55–08:46] Holmes: "This is undoubtedly a code message. The Baconian bilateral cipher depends upon the use of two sizes of type..."
  • The message reads: “HELP QUILTER ELMS PENGE”
  • Watson’s deduction: "Presumably there’s a man named Quilter who lives at a house called the Elms in the village of Penge. Needs help." [09:03]

3. Arrival at The Elms, Penge

• Holmes, Watson, and Levia immediately travel to The Elms. Ominous events occur as they approach: they hear revolver shots.
  • [11:03] Holmes: “You see, Levia? The English have more imagination than you give them credit for.”
  • Holmes dismisses the shots as casual target practice, not murder—a detail that unsettles Levia.

4. The Eccentric Household

• The trio meets:

  • Doris Faversham, the niece, an adept markswoman.
  • Mr. Quilter, supposedly paralyzed and confined to a wheelchair.
  • Mr. Davis, an alleged Australian relation.

• Suspicious details:

  • Mr. Quilter seems dismissive and unfazed by their presence, revealing he sent the message not for help, but to lure a brilliant mind to help prove his theory that Bacon wrote Shakespeare’s plays. He offers Holmes a “handsome fee.”
  • [15:12] Quilter: "I was sure that anyone who was able to decipher my message was the man I needed... Name your fee."
  • Holmes politely refuses: "An interesting subject... but I’m much too busy to undertake such an assignment." [15:44]

5. Holmes’s Doubts and Realization

• As they prepare to leave, Holmes expresses grave concern:
  • [17:06] “He’s in desperate danger... I’m only afraid I may be too late to save him.”
  • He points out an observational detail: “Did neither of you notice the traces of fresh loam on the boots of that supposedly paralyzed man?” [17:12]
  • Holmes deduces impersonation and possible murder: “Gentlemen, I fear the Agony Column has led us to murder.” [17:33]

6. Investigating the Grounds

• Interviews with the gardener corroborate that Mr. Quilter smuggled out the coded message via the gardener, under nervous circumstances. No one has entered or left since the morning; thus, the real Quilter must still be in the house.

  • [21:11–21:35] Gardener: “He told me to take [the message] to the village office of the Times and to tell them to print it just the way it was. He looked kind of worried when he gave me the message...”

7. Holmes’s Ruse: The Shooting Match

• Holmes leverages Doris’s vanity—accepting a pistol match to gain access to the house and grounds.
• In the middle of the shooting match, Holmes turns the tables, brandishing the gun and demanding Doris and her cohort surrender:
  • [23:54] Doris: “Then why are you pointing it at me?”
    Holmes: “Because I want you to raise your hands above your head...”

8. Climax: Discovery of the Real Quilter

• The plot unravels quickly:

  • Holmes confronts Doris and Davis, insisting they return to the study where the “paralyzed” Quilter sits.
  • Holmes realizes, prompted by Watson, that the real Quilter—drugged and unconscious—sits in his own wheelchair, cleverly hidden in plain sight; Davis had impersonated Quilter earlier.
  • [26:03] Holmes: “Listen to the breathing of that man in the chair. He’s been drugged. There sits the real Mr. Quilter...”

• Doris and Davis are implicated in a plot to seize his estate, reveal their mutual guilt in a heated exchange.

  • [26:38] Doris: “It was Jeffrey’s idea, not mine!...”
    Davis: “That’s a dirty lie. You were in this as much as I am.”
  • [26:51] Holmes: “If Mr. Quilter revives under Dr. Watson’s ministrations, you’ll be charged, I have no doubt, with attempted murder, abduction, sequestration, duress, and probably several other counts...”

Notable Quotes & Memorable Moments

• Holmes on the English criminal:
  “Let me see. Oh, yes, yes, of course... the Agony Column. This should convince you of the color and variety of English life.” [05:56]

• Holmes deciphers the cipher:
  “If we group the letters in units of 5, the arrangements of small and capital letters within the group should give us the message…” [08:04]

• Holmes, on being ‘fooled’:
  “He's in desperate danger. I’m only afraid I may be too late to save him.” [17:06]

• Watson humorously to Holmes:
  “Holmes, old fellow, you’re losing your touch. You’d never have made a blunder like this if I’d still been with you.” [16:43]

Epilogue and Future Stories

• The episode closes in the familiar, warm banter between Dr. Watson, his friend Gregory Hood (introduced as a guest for the summer series), and Harry Bartell. Listeners are encouraged to tune in for more detective adventures from Gregory Hood while Dr. Watson is away in England.

  • [28:54] Dr. Watson: “Meanwhile, I’ve asked Mr. Gregory Hood to get together with you at this time every week and tell you some of his experiences…”

Tone and Atmosphere

• The episode is filled with the genteel, witty, and slightly droll manner characteristic of mid-century Sherlock Holmes radio. Holmes is dry and incisive, Watson warm and earnest, and the interplay with Levia adds a touch of international rivalry and charm.

Takeaway

This tightly plotted radio mystery delivers everything classic Holmes fans love: cryptography, sudden action, keen observation, and the satisfaction of justice properly served. The playful arguments over Anglo-French criminality and the layers of impersonation are especially rewarding for listeners who relish both puzzles and character-driven banter.

As Holmes himself quips:
"The game's afoot." [10:12]
