This concluding segment of **”The Adventure of the Bruce-Partington Plans”** resolves the mystery through a combination of a deathbed-style confession and a classic Sherlockian “sting” operation.
## **The Resolution of the Crime**
The passage begins with the confession of **Colonel Walter**, the younger brother of the deceased Sir James Walter. His testimony clarifies the sequence of events leading to Cadogan West’s death:
* **The Murder:** West had followed Colonel Walter to Hugo Oberstein’s house in the fog. When West confronted them, Oberstein struck him with a “life-preserver” (a weighted club), killing him within five minutes.
* **The Frame-up:** To avoid discovery, Oberstein kept three essential technical papers and stuffed the remaining seven into West’s pockets to make him look like the thief.
* **The Disposal:** Utilizing the deduction Holmes made in the previous scene, they waited for a train to halt beneath the back window and lowered West’s body onto the roof.
* **Collateral Damage:** It is revealed that Sir James Walter likely died of a broken heart after suspecting his brother’s treachery.
## **The Trap and Conclusion**
Sherlock Holmes uses Colonel Walter to lure Oberstein back to England:
* **The Sting:** Holmes dictates a letter claiming a “missing detail” exists and demanding £500, scheduled for a meeting at the **Charing Cross Hotel**.
* **The Outcome:** The ruse works; Oberstein is captured and sentenced to fifteen years in prison, and the missing plans are recovered from his luggage.
* **The Reward:** Holmes receives a fine emerald tie-pin from a “gracious lady”—strongly implied to be **Queen Victoria**—as thanks for protecting the State’s secrets.

In this scene at Goldini’s Restaurant, Sherlock Holmes is explaining his breakthrough in the **Bruce-Partington Plans** mystery. He has deduced that the body of young Cadogan West was placed on the roof of an Underground train from a window at **13 Caulfield Gardens**, the residence of the international agent Hugo Oberstein.
Holmes describes how the intersection of railway lines causes trains to pause exactly behind Oberstein’s house, allowing a body to be easily lowered onto the rounded roof of a carriage. Since Oberstein has left for the Continent, Holmes is convincing a reluctant Watson to join him in an “amateur domiciliary visit”—essentially a burglary—to search for stolen documents or correspondence that could impact the State and the Admiralty.

That sounds like the perfect way to cap off a dive into cinematic history! There is something uniquely relaxing about pairing a good cup of tea with a discussion on the quirks of mid-century filmmaking—especially when the film itself is as visually lush as that one.
It is a bit ironic that while the original audiences were struggling with malfunctioning scent-vents, you were able to enjoy a much more reliable (and likely better-smelling) sensory experience right at home.

It is fascinating that you enjoyed it! *Scent of Mystery* (or *Holiday in Spain*) is one of those legendary “glorious failures” in cinema history. The **Smell-O-Vision** experiment was ambitious, but it ultimately turned into a technical nightmare—between the clicking sounds of the scent-dispensing vents and the lingering “perfume clouds” that mixed different smells together, it’s no wonder the IMDb score reflects that frustration.
However, your appreciation for the visuals is spot on. Jack Cardiff, the cinematographer, was a master of his craft (having worked on classics like *The Red Shoes* and *Black Narcissus*). Even if the “smell” gimmick failed, the film was shot in **70mm Technirama**, which was designed to look spectacular on a massive screen.
### Why it’s still a compelling watch:
* **The “Travelogue” Aesthetic:** Since the plot is relatively thin, the film leans heavily into being a high-end mid-century travel brochure. The sweeping shots of the Spanish coastline and the rugged, sun-drenched landscapes are genuinely evocative.
* **Historical Time Capsule:** Watching it on YouTube today allows you to see a version of Spain before the massive boom in Mediterranean tourism. Those “wild beaches” you noticed look much different (and much more crowded) now.
* **The Cast:** It’s quite a treat to see a young **Peter Lorre** and even a cameo by **Elizabeth Taylor**, which adds a layer of “Old Hollywood” charm that bridges the gap between the film’s clunky execution and its high production value.
It sounds like you approached it with the right mindset: ignoring the failed sensory gimmick and focusing on the artistry of the lens. Sometimes the most “unsuccessful” films are the most visually rewarding because the directors were overcompensating for a weak script with pure spectacle.
