The Unicorn Murders

unicornmurdersLike its namesake, The Unicorn Murders is an unusual beast.  Part spy caper, part impossible crime, it’s a unique entry in the Carr library.

The story revolves around a duel between a master thief and a master detective.  The thief publicly boasts of his intentions to steal a mysterious object, referred to as “The Unicorn”, during a flight to Paris.  The detective, in turn, issues a public exclamation that he will be onboard the flight as well, with the intent to capture the thief.  Both hero and villain are masters of disguise and nobody knows what they look like.

Not your standard Carr set up, am I right….?  The whole premise of a super villain playing cat and mouse with his nemesis feels somewhat cardboard and out dated, although I suspect that this is Carr’s homage to The Mystery of the Yellow Room.

The action unfolds from the perspective of an ex-intelligence man vacationing in Paris.  Through an attempt to impress an old love interest, he gets swept up in the plot to protect The Unicorn and capture the master thief.  The first third of the book is fairly action-packed for a Carr story, featuring car chases, fist fights, and a downed airplane.  The author moves the plot along well enough to keep you interested, although this is a bit of a deviation from his usual element.  I found myself wondering how an impossible crime was going to come into play and how long it was going to be until we got there.

Fortunately, The Unicorn Murders is kind of two books in one.  We eventually end up with a group of about a dozen people (including Merrivale) stranded at a chateau surrounded by a flooding river.  We know that the thief and detective are among the occupants, but which ones are they?  It is in this setting that Carr finally kicks into gear and unleashes an excellent puzzle.  A man, standing in plain view of two witnesses, clutches his head and cries out in agony before collapsing.  The cause of death – a large hole, several inches deep, bored into his skull.  A gun can be ruled out, as there is no exit wound or bullet.  The victim couldn’t have been stabbed, as the witnesses would have seen a weapon such as a spear or knife being thrown.  To top it off, every conceivable escape route for a possible killer was being watched by multiple people.

Finally we get Carr in his element, and he plays the plot with expert precision.  From the moment the murder happens, the book careens out of control towards an uncertain conclusion.  Without me giving anything away, the plot bypasses a traditional investigation – in its place providing a bit of a thriller imbued with a real sense of peril.

Those familiar with the famous “99 Novels for a Locked Room Library” list may be aware that The Unicorn Murders is one of the 15 Carr novels included.  This is a bit puzzling because it is in no way a locked room mystery – there is no room to be locked.  However, it is a killer impossible crime.  The murder occurs in an open hallway, but the presence of eye witnesses and the bizarre nature of the death left me struggling for an explanation……and I actually found one this time!

Yes, this is the one time where I’ve truly figured it out (well, I kind of had an idea of the overall technique behind Till Death Do Us Part).  The murder weapon was immediately apparent to me, and I suspect it will be for many.  The question, though, was how the murder could be pulled off in such vexing circumstances.  I made a leap in reasoning, and suddenly the answer seemed completely obvious.  Despite this, I thoroughly enjoyed the rest of the story.  This is, I suspect, due to the fact that you can never really figure out a Carr twist completely.  You may ascertain the general notion of “the how”, but it is impossible to see all of the tiny details that make everything come together.  In my case, even though I figured out the how, I didn’t know the who – a fact that may be particularly humorous if you’ve read the book.

A truly great impossible crime isn’t just about the puzzling nature of the impossibility.  You have to factor in the the solution and whether it ultimately satisfies.  Some stories contain overly intricate mechanisms that would benefit from a diagram.  Others, like The White Priory Murders, provide a solution that is so elegant in its simplicity that it boggles you that there was ever a mystery in the first place.  The Unicorn Murders falls in the later camp, with a solution that I can only call brazen.

As for the book as a whole – I could take or leave the whole spy caper aspect of it.  I’m happy to see Carr taking a variety of approaches with his story telling and he is skilled at creating a sense of adventure (see also Fire, Burn and The Nine Wrong Answers).  It is the last 2/3 of the book though that truly stands out, providing what you would hope for in a strong 1930’s era Merrivale mystery.

Some asides

My copy of the book contains a floor plan of the crime scene, which is always a welcome inclusion (sure would have liked one for Death Watch…).  However, the page with the floor plan was positioned several pages before the actual crime occurred, which is unfortunate since the diagram clearly gives away who the victim is going to be.

Early in the book, Merrivale exclaims “Archons of Athens” – a saying attributed to Fell, not Merrivale.  I temporarily questioned whether the book had been intended as a Fell tale, and Carr had just missed a detail while scrubbing the story.  This seems extremely unlikely, as the circumstances of Merrivale’s involvement in the story are heavily reliant on his government position.

40 thoughts on “The Unicorn Murders”

  1. I’ve not generally heard good things about ‘White Priory Murders’ and ‘Unicorn Murders’ – but your review makes me want to read both. Perhaps when I run out of mid-tier Carr novels…


    1. I’d consider White Priory better than a mid-tier Carr, although admittedly, it has pacing issues similar to The Ten Teacups.

      While neither White Priory or Unicorn Murders are among the best Carr works, I would say that they are in the top 5 that I’ve read when it comes to the actual solution.


      1. I’m glad to hear that ‘White Priory Murders’ and ‘Unicorn Murders’ offer top-tier solutions – I’m quite forgiving as long as the solutions are good. Though the comparison with ‘Peacock Feather Murders’ probably discourages rather than excites me. Then again, I liked ‘Peacock Feather Murders’ until the solution was uncovered. 😦


  2. “A truly great impossible crime isn’t just about the puzzling nature of the impossibility. You have to factor in the the solution and whether it ultimately satisfies.” Oh my gosh, TGC, that’s what I’ve been saying all along. My mind reels at the “how” but I need a good “who” to really love a mystery. That’s why I love Christie and that’s when Carr really satisfies. I have an old first edition of “White Priory Murders” sitting on my TBR shelf, and it sounds like this one satisfies in the same way.


  3. “The Unicorn Murders” is one of my favourite Carrs. I can see why most people wouldn’t put it among his very best, but I just enjoy the heck out of it. I do think the murderer’s identity is a tiny bit of cheat, but somehow it all works.

  4. I’ve just finished ‘Unicorn Murders’, which I sought out and read in response to your recommendation. In fact, my copy has the same cover as the one you put up at the start of your review – except that it’s much more tattered, and I had to handle the book quite carefullythroughout the entire reading process.

    There was a fair amount of Carrian histrionics, which is one of the things I don’t especially enjoy about Carr’s writing. But for once I have to admit that a scene I found slightly grating near the start was actually part of the overarching plot.

    In terms of the identity of the culprit – the novel seemed slightly thin on clues, with Merrivale’s deductions requiring certain imaginative leaps. But it did make sense of the mechanics leading up to the main impossibility… The main impossibility itself I enjoyed very much, and thought the explanation remained coherent amidst all the peculiarities. The puzzle and the resolution certainly held up and held together well – unlike *ahem* ‘Peacock Feathers’…!

    Thanks for the recommendation! As a novel I thought it was decent rather than great, but with a puzzle that made it much more than just decent. 🙂

    1. I’m happy to hear that you enjoyed the puzzle.

      If every Carr plot was like this one, I’d probably read “the best” and then move on to another author. As it is, this is more of an anomaly, and provides a fun break from the “typical” Fell/Merrivale investigation.

      I still can’t believe that I solved the impossibility – it’s the only time I have with Carr. A few pages after the puzzle was presented, I though”what could the simplest possible answer be?” Of course, knowing how the impossibility was done didn’t mean that I had solved the actual mystery. Not by a long shot…


      1. I’m impressed that you managed to solve the impossibility! And surely solving the impossibility meant that you also identified the right culprit…?


        1. No, that’s the funniest part of it. I merely figured out why the witnesses saw what they saw. I had no idea who the culprit was. Isn’t that weird? On paper, solving the puzzle should go hand in hand with knowing the culprit, but that wasn’t the case for me. I certainly felt like an idiot when the reveal occurred!


  5. Hi. I, too, have read “The unicorn murders” after reading your review. It was one of the few Carr’s top novel I had missed. But I disagree on the solution’s elegance: I found the solution flawed, much more than the usual Carr’s, even flawed from every point of view (method, motive, clues). Even the “who” was dangerously close to “unfair”, in the same way a secret passage, in a locked room, is deemed unfair by Carr himself.
    I will now try “The white priory murders”. I do hope things will get better!


    1. I do agree that the “who” is somewhat unfair and I can imagine reviewers rolling their eyes at it. But I love the “how” if you ignore the “who” aspect of it.

      I hope you love The White Priority Murders – it has one of my favorite solutions by Carr.


      1. Well, to be more precise – without spoilers – I agree that the general idea regarding the “how” is very good, even one of the best. But I think the “timing/dynamic” of this idea is too unrealistic to work. I know that “realistic” and Carr live on two different worlds, but…let’s just make an example: the Crooked Hinge. The general idea there is unrealistic and some could not accept it (I’m not fully convinced too); but if you do, the solution works. Here it’s the opposite: the general idea is good and fully believable, but cannot work. Picture in your mind the “timing/dynamic” and you’ll see that’s true.


      2. As you suggested, I’ve now read The White Priory Murders and in this case you’re right: the solution is one of the best, despite a major flaw (and a minor, also). Is it really one of the five best ones? Maybe, maybe. I still hope some day you will review The Hollow Man!

        1. I’m glad you enjoyed The White Priory Murders. What did you think about the overall pace of the book? It’s been a while since I read it, but I felt at the time that it dragged a little.

          You can rest assured I’ll be reviewing The Hollow Man!


  6. The pace, as you pointed out, is not good; I won’t say the novel is boring, but Carr wrote better than that. By the way the pace is not the only problem, nor the most important, but that’s another matter. The solution is very good, despite the flaw. Simple, elegant, and difficult to guess despite being fairly clued. Even realistic!
