Starring: Basil Rathbone (Holmes), Nigel Bruce (Watson)
Key Segment: 09:39–34:23

Plot Summary & Discussion Points

• Dr. Watson recounts an adventure involving the enigmatic and alluring Lady Venering (formerly Jasmine La Fleur, magician’s assistant), who has lost three husbands—each murdered on their wedding night (10:05–12:13).
• Holmes is approached by the Rev. Arthur Whalen. Whalen invokes the Old Testament Book of Tobit: in it, a demon (Asmodeus) kills all of a certain woman’s husbands on their wedding night (12:36–16:16).
• Whalen reports that Lady Venering’s late husbands all received threatening notes signed in Hebrew as ‘Asmodeus’ (15:51–16:16).
• Holmes and Watson visit Lady Venering. She is witty and self-assured, recognizes Holmes’s doubts, and reveals she is already secretly (and recently) married to Major Beckwith, her latest fiancé and recently-acquitted murder suspect (18:16–22:27).
• Beckwith has just been murdered, stabbed in his bath (22:36–23:05).
• Holmes grows fascinated by Lady Venering’s strength and composure: “What courage. What unconquerable spirit in the face of a fresh tragedy. Watson, she fascinates me.” (Holmes, 23:29)
• The investigation stalls for a month, with Holmes increasingly involved with Lady Venering—Watson fears he’s falling under her spell (25:20–27:01).
• Holmes announces he’s marrying Diana (Lady Venering). Watson is stunned: "Three of her husbands murdered on their wedding nights. You’re proposing to be the fourth?” (Watson, 27:54)
• At the wedding, Holmes receives his own threatening letter. In a dramatic confrontation, Lady Venering tries to murder Holmes, exposing herself as the culprit (31:06–32:33).
• Holmes explains the misdirection—a magician’s talent—was key, as Lady Venering successfully deflected suspicion. He pretended to marry her to draw her out (33:11–33:57).
• The case ends with Holmes not actually married, thanks to a fake ceremony (with brother Mycroft in disguise as the clergyman).

Starring: Gerald Mohr
Key Segment: 37:27–64:41

Plot Summary & Discussion Points

• Marlowe is hired by a grim, desperate husband (Carl Delaney) whose wife, Norma, has vanished (38:50–39:09).
• Norma “always comes back” after quarrels, but this time is different; Delaney suspects suicide (39:26).
• First clues: an odd horoscope, a mysterious caller “Madame Jeanette,” and Norma’s solitary ways.
• Marlowe tracks ‘Madame Jeanette’ to a bar—she’s a sly, inebriated fortune teller about to skip town (42:23–44:48). A shifty newsboy and a drunk hang-about named Pinky add comic color.
• Norma’s ex-lover Pierre Gillum is introduced as a potential suspect/ally (48:32–51:00). The men nearly come to blows over complicity and motives.
• Clues: a powder blue coupe, white gloves, and a pair of Persian slippers link Norma and Jeanette. After a tense and witty parley, Marlowe is knocked out by Norma herself (52:29).
• A staged murder/suicide: Carl is killed, a confession left, and a spectacular car wreck with a woman’s body presumed to be Norma’s.
• Twist: The body is not Norma but Jeanette in disguise (wearing Persian slippers); Norma staged the entire scenario with Gillum as her accomplice.
• Marlowe exposes the ruse and delivers the moral punchline, recognizing the complex line between guilt and innocence: “A pair of Persian slippers has two soles and two heels, and it's hard to tell just exactly where the one becomes the other.” (Marlowe, 64:13)

• Spade receives a mysterious, passionate love letter (from Ella), yet can't remember her and suspects it’s a veiled cry for help (69:11–69:51).
• Following cryptic instructions, Spade meets a woman who claims she’s escaping an insane uncle. This launches a madcap chase involving ladders, shots in the night, and heaps of jewelry.
• Amid mistaken identities, Ella’s wealthy family, and a series of previous “unlucky” fiancés, Spade is accused of both elopement and blackmail.

Episode Structure & Flow

The episode flows from host’s introduction (setting the romance-gone-wrong theme) through four dramatized tales, each using wit and drama to explore the intersections of love, trust, deception, and—inevitably—violent crime.

Common threads:

• Femme fatales and dangerous paramours appear across multiple stories.
• Detectives are lured not just by cases but by personal entanglements.
• The motif of secret marriages, forged documents, and inheritance disputes ties the dramas together.

Conclusion

• This Valentine’s aftermath edition of Down These Mean Streets underscores the dangers—comic and tragic—of love among detectives. From Holmes and Spade’s fake weddings to Marlowe’s deadly Persian slippers and Diamond’s brush with hypnotic murder, relationship drama is both catalyst and complication in the world of radio’s greatest sleuths.

Host’s Closing:

“Thanks so much for joining me. I’ll be back next week with more old-time radio detectives. … Good night and happy listening.”
