Hercule Poirot #0.18

The Double Clue: a Hercule Poirot Short Story

In Agatha Christie's short story, "The Double Clue," Poirot investigates the robbery of a collection of medieval jewelry from the safe of a dealer - including a necklace said to have belonged to Catherine de' Medici! Since the theft occurred during a dinner party, the suspects could be any of the guests. But which one? This short story originally appeared in the December 5, 1923, issue of "The Sketch" magazine.

PS. We get to meet Countess Vera Rossakoff once again! One of the author's great minor characters. And a favourite of Poirot.

Double Clue!? <--That's 2 clues too many, bitches.
And everyone's favorite Belgian detective is onto that shit.

description

Someone from a house party made off with a goodie bag full of jewels stolen from their host. And it's up to Poirot to ferret out which guest has sticky fingers.
Countess Vera Rossakoff stars in this one, and I'm pretty sure Poirot's eyes turn into actual hearts and bulge out of his head.
It's cute.

If you're looking to kill 20 minutes with a cozy mystery, then this one will fit the bill.

Recommended for Christie fans.

Also read as part of the short story collection A Deadly Affair.

The poorest one from this series, so far.
It is too short to contain something valuable, the plot is thin, the clue with the Russian alphabet is quite obsolete. Not to mention the lack of proofs...

PS: I love Agatha and perhaps sometimes I'm too harsh on her, this could be a reason for those poor ratings.

4 Stars. A little simplistic with one pleasant surprise. It relates to my only enjoyable memory of Christie's 1927 novel, The Big Four. We'll get to that. The story was in Sketch in 1923 and Hercule Poirot The Complete Short Stories of 1999. Mr. Marcus Hardman visits Poirot about a delicate matter. "But above everything - no publicity!" He collects fine jewellry. Recently, at a small party he hosted, some rubies and emeralds disappeared from his private safe. Like good collectors to this day, he alludes to a possible provenance, an "emerald necklace said to have belonged to Catherine de' Medici." Who was there? Mr. Johnston, the South African millionaire, Lady Runcorn, a society force in various charities, Bernard Parker, a young fellow "not perhaps, quite in the swim, [who has] performed little commissions for me," and Countess Vera Rossakoff who we met in The Big Four, a member of the old regime in Russia and one of Agatha Christie's great minor characters. My pleasant surprise. The story is an early reference to gay people in main stream literature - not the best, but for a century ago, it could have been much worse. I liked it. (Ja2021/Jul2026)

OMG, Hercule what have you done (all in the name of love?)

An excellent story, Ms Christie takes Poirot where I think he has never gone before. A stunner of an ending.

Short and the tv show was definitely better! Jewels have been stolen during a party and Poirot is looking for them. Hastings was really useless in this one...

I'm pretty sure I read this in a collection of Christie shorts years back, but I didn't remember who was guilty, so it was fine.

Recommended if you're looking for a short, harmless (i.e. no one dies, or even goes to jail) mystery.

"Double Clue: A Short Story" by Agatha Christie follows detective Hercule Poirot as he investigates the disappearance of valuable jewels.

The story completes, even before, you want it. Although, one can easily guess the thief, it is Hercule Poirot, who shows us how in his convincing manner.

Overall, a good story. Agatha Christie mystery that is sure a good-read and you get that satisfaction of reading a good mystery.

Sorry but engaging and the ending was clever without being impossible. Fraser does a good job narrating as always. [AUDIBLE]

Review of the short story, The Double Clue.

Marcus Hardman, an antique collector has a weakness for medieval jewels and showing off his prized collections.

At one of his parties, after showing off as usual, the safe appears not to have been closed correctly. One of four of his guests could have had the opportunity to lift the gems, so he asks Poirot to help him recover his property to save a scandal should this police become involved.

Another early story of Poirot’s cases, with the benefit of Hastings, bright but no halogen bulb. Here he echoes our struggle to see the culprit from among Hardman’s friends. Sometimes I think his confusion leads to our own. If we follow Poirot’s discoveries and actions. What he says and where he goes we’d have a better idea how to interpret the evidence presented.

Here we have two clues for the price of one in and around the safe. The Double Clue seems a little excessive but does it point to misdirection, a Red Herring or simply a careless thief?

Perhaps all three such is the web that Christie weaves.

The story is important also in introducing the character of Only four people had the opportunity to steal Marcus Hardman’s medieval jewels and when Poirot examines the scene of the crime he finds two clues which will lead to the culprit. This story is one of Poirot’s few encounters with Countess Vera Rossakoff, a woman he reciprocated a mutual respect and to be a potential love interest.
Similar to an Irene Adler as to Sherlock Holmes.

I did not see how Poirot figures this one out or what that countess’ motive was for absolving the young man accused of the theft. It was an interesting story and I suspect that we will hear from the countess again, given Poirot’s comment at the end, so maybe things will make more sense when we see her again.

I’m of the opinion that any story with Countess Vera Rossakoff is a good story. 20 minutes of listening, but it feels satisfying because Poirot has to do some sleuthing. And Hastings doesn’t have time to act stupid, so that’s always a plus.

I love Agatha Christie but I usually do not enjoy her short stories and this one is not an exception. I mean this jewel thief was so careless, makes me think it's almost like a kids game of Clue 🙄
2 stars for the story, 1 star for Charles Armstrong's recital of the book 🙂

I wonder that so many of these stories point out the duplicity of the class system in England. Those born to a title are everything and not to be crossed, and the rest of us are disposable and suspects. I do like the use of languages in the solving of this mystery. Good job, Poirot.

Well, the who was easy to figure out, but how did Poirot know, that was his secret.
Enjoyable short story!

A very short and simple story. I actually like the premise, stolen jewels and two (or double) clues pointing to one of the guests of the man whose jewels were stolen.

SPOILERS?

Despite the letter on a glove that was found in the crime scene pointed to said man, Poirot figured out that the letters they saw represented different letters in the Russian alphabet, and that a Russian woman was the jewel thief, who handed over the jewels with no fuss when Poirot asked for them. As I said, I liked the premise, but I would have liked it if it were a bit longer, and written a bit more elaborately.

Interesting plot of missing jewels and not just one clue but two pointing at a young gentleman. One mistake could be an accident or a plant but two just seems wrong to poirot. What is the clue and what is the distraction. Russian language skills are a clue to the untangling the threads.

First a Marple in this collection, then a Poirot, and one that I haven't gotten to reading at that! And I'm pretty sure I've only watched the Suchet adaptation of this once, even if subsequent episodes stick Countess Vera Rasakoff in where she never was. I digress. Another short, singular puzzle, and its abruptness is a slight takeaway from it--I like spending time with Poirot and Hastings!--but it's still a fun puzzle with a surprise solution that those with a certain frame of knowledge might be able to figure out (it's a clue that Christie used again in one of her more famous novels, but it's a good one). Worth the read!

My rating: 4.25/5 (rounded down)
Would I own/re-read?: Sure!
TW: No triggers in the case of this Double Clue, honestly.
Does the animal die?: Nor are there any animals harmed!
How difficult was the mystery?: As explained above, it's short and the pool is small, so it's not an insurmountable achievement even if guessing, but there is a logical solution.
