Episode Overview

This episode features "The Merry Murder Case," a classic Philo Vance detective story from the golden age of radio. In this suspenseful installment, the celebrated amateur sleuth Philo Vance unravels a perplexing murder involving three women, hypnosis, and a web of psychological intrigue. The case centers on the killing of Joseph Mary, a lecturer on applied psychology, whose death appears tied to subconscious impulses, past relationships, and a diabolical manipulation of the human mind.

Key Discussion Points & Plot Progression

1. The Psychology Lecture That Sparks Murder

[00:24-01:24]

• Joseph Mary presents a lecture on applied psychology, discussing the power of the subconscious and the notion that removing its restraints could let it dominate actions.
• Audience Q&A emphasizes his theories on the subconscious mind (notably, Francis Adams's question).

2. The Aftermath: Three Women, Three Guns, and No Memory

[04:22-07:08]

• Alice Barclay arrives, distressed, to Philo Vance, claiming she killed a man but cannot remember anything before finding herself with a gun over the victim’s body.
• Vance investigates and finds the murder weapon is in Alice's possession—but soon, two more women, Joan Anderson and Francis Adams, are also connected, each having brought a gun to the lecture and being equally uncertain of their own actions.

3. The Investigation: Unraveling a Complex Case

[07:23-13:13]

• Enter Sgt. Heath, District Attorney Markham, and Vance banter over the open-and-shut nature of the case: all evidence points to one of the three women.
• Medical examiner's revelation: Joseph Mary was shot three times — three different bullets, three different guns, fired in close succession. It’s unclear who actually fired the fatal first shot.
• Vance proposes ballistics testing; all three women's guns did, in fact, fire into Mary's body.

4. The Hypnosis Theory

[16:36-18:31]

• Vance consults Professor Colby about hypnotism and its limits. Colby clarifies that hypnosis cannot force someone to act against their moral code, but post-hypnotic suggestion can compel apparently purposeless acts.
• Vance arranges for all three women to be hypnotized to probe for suppressed memories.

5. The Hypnosis Experiment & The Exposed Deception

[18:31-21:08]

• Vance, Professor Colby, and Markham hypnotize Alice, Joan, and Francis.
• As part of the test, Vance subtly pricks each woman's hand with a hatpin; only Frances Adams has a physical reaction, revealing she is faking hypnosis and thus has something to hide.
• None of the women, while under hypnosis, can duplicate the act of shooting Joseph Mary, indicating deep-seated psychological interference at play.

6. The Confrontation & Confession Setup

[21:31-23:35]

• Vance enlists Alice to feign blackmailing Francis Adams, drawing out a confession.
• Francis is goaded into admitting to hypnotizing Joan and Alice, planting a post-hypnotic suggestion to bring their guns.
• In a climactic moment, Francis attempts to kill Alice, but Vance and the police intervene just in time.

7. The Resolution: The Psychology of Murder

[24:16-25:14]

• In a final discussion with his secretary, Ms. Deering, Vance explains that Frances Adams faked hypnosis to avoid exposure, the hat pin test proving her duplicity.
• Frances's motive: she was once married to Joseph Mary, who later stole her money and jewelry following their divorce, providing a classic motive for revenge.

Notable Quotes & Memorable Moments

On the Subconscious:

• Joseph Mary “[00:43]**:
  "The subconscious is held in check by a controlling band... Were it possible to remove that controlling influence, I am of the opinion that the subconscious would dominate our motivations."

On the Unusual Nature of the Case:

• Philo Vance [03:08]:
  "I believe I've reached the epitome of success as a private investigator. I'm so private that I haven't had an interesting or unusual client in a week."

The Medical Examiner’s Bombshell:

• Joseph Mary (Medical Examiner) [10:13]:
  "Here were three bullets."
  (Revealing the truly bizarre nature of the murder: three bullets, three guns, three suspects.)

On the Confusion:

• Sergeant Heath [12:44]:
  "Vance, do me a favor. Say that you're a little confused by all of this, too."
• Philo Vance [12:58]:
  "All right, Heath, if it'll give you any satisfaction, I'm confused."

Explaining the Hypnotic Trap:

• Professor Colby [16:55]:
  "Nobody can be hypnotized into doing anything that's against his moral code."

• Philo Vance [19:26]:
  "It's his theory and mine that under hypnosis, if hypnotism was used once before, the subconscious mind will recall what was done at that time."

The Reveal:

• Philo Vance [24:24]:
  "When Professor Colby hypnotized the three ladies, only two of them were really hypnotized. The actual murderer, Frances Adams, fought against it, knowing her subconscious mind, which she could not control, might reveal something to us."
