Narrated by Choice Classic Radio, this episode masterfully adapts the classic Holmesian mystery, weaving intricate plotlines and rich character interactions that engage both longtime fans and newcomers alike.

A Change in Atmosphere

The episode opens on a crisp October morning at 221B Baker Street. Dr. John Watson observes the last leaves falling from the solitary plane tree, anticipating Sherlock Holmes's usually gloomy demeanor. Contrary to Watson's expectation, Holmes exudes a “sinister cheerfulness” ([00:40]), hinting at an underlying case that has captured his interest.

Dr. John Watson: “I was dressing and noticed the last leaves twirled from the plane tree. I expected Holmes to be in depressed spirits, but he was in a mood of sinister cheerfulness.” ([00:40])

Holmes quickly confirms that his unusual mood is indeed due to a new case involving a letter that caught his attention.

The Mysterious Letter

Holmes reveals a letter from J. Neil Gibson, an influential American senator and gold mining magnate residing in Hampshire. The letter is a plea for Holmes's assistance in proving the innocence of Ms. Grace Dunbar, who has been wrongfully accused of murder.

Sherlock Holmes: “There is an exception then.” ([01:31])

J. Neil Gibson’s Letter: “I can't see the best woman God ever made go to her death. I know beyond all doubt that Ms. Dunbar is innocent. I shall come at 11 tomorrow...” ([01:57])

Holmes and Watson discuss the details of the case, noting that despite the coroner’s jury and police court viewing the evidence as clear-cut, Holmes remains skeptical and sees potential for unraveling the truth.

Meeting the Client

At 05:30, J. Neil Gibson arrives at Baker Street, seeking Holmes’s expertise to exonerate Grace Dunbar. Holmes introduces Watson, who immediately engages with Gibson, probing into the depths of the case.

Neil Gibson: “Money is nothing to me in this case. You can burn it if it’ll light the way to the truth...” ([05:43])

Holmes maintains his professional demeanor, stating his preference for anonymity and his commitment to uncovering the facts without swaying influences.

Sherlock Holmes: “I prefer to work anonymously. Let us get down to the facts.” ([06:16])

Gibson outlines his relationship with Grace Dunbar, highlighting his waning marriage and his inappropriate feelings towards his governess, which he believes may have led to the tragic events.

Investigating Thor Bridge

Holmes and Watson accompany Gibson to the crime scene at Thor Bridge. They meet Sergeant Helms, who provides a preliminary report of the murder. The victim, Gibson's wife, was found with a revolver bullet through her brain, and a note in her hand indicating a meeting at the bridge.

Sergeant Helms: “She was waiting there for me. She was like a mad woman...” ([20:46])

Holmes meticulously examines the evidence, questioning the plausibility of the alibi and the presence of the revolver in Ms. Dunbar’s wardrobe. He deduces inconsistencies in the governess’s statements and the placement of the weapon, suspecting a deeper deception.

Sherlock Holmes: “The finding of the revolver in her wardrobe... I think I should like to sit quietly for a few minutes and figure out.” ([14:42])

The Revolver Test

To test his theory, Holmes orchestrates an ingenious experiment involving Watson’s revolver, a stone, and a piece of string. The demonstration is designed to reveal the mechanics of the murder and the likelihood of Grace Dunbar’s innocence.

Sherlock Holmes: “We must perform a test. If it comes off, all will be clear. If it doesn't...” ([23:19])

During the test, Holmes simulates the murder scenario, illustrating how the revolver could have been manipulated to create the appearance of Grace Dunbar’s involvement while absolving her of direct responsibility.

Sherlock Holmes: “This is the spot for Thor Bridge, eh? That's it Doctor...” ([13:08])

The successful test leads Holmes to firmly believe in Grace Dunbar’s innocence, cementing his resolve to uncover the truth behind the murder.

Confronting the Truth

Back at Baker Street, Holmes shares his revelations with Watson, revealing that the letter found in Grace Dunbar’s hand was a cleverly planted clue intended to frame her. The real perpetrator orchestrated the scene to divert suspicion away from themselves, using the pair of revolvers to facilitate the deception.

Sherlock Holmes: “A note was extracted cleverly from Ms. Dunbar which would make it appear that she had chosen the time and place for the crime.” ([25:21])

Holmes concludes that the murderer must have planted the revolver to incriminate Grace, solidifying his theory that Ms. Dunbar is innocent and that the true culprit is someone else with the means and motive to commit the crime.

Sherlock Holmes: “Her first resolution was to end her own life. Her second was to involve the victim of her hatred.” ([26:34])

Conclusion

In a brilliant display of deductive reasoning, Sherlock Holmes unravels the complexities of the Thor Bridge case, exonerating Grace Dunbar and exposing the intricate plot devised to conceal the true murderer. The episode underscores Holmes’s unparalleled ability to perceive hidden truths and his unwavering dedication to justice.
