The Maddest of All

From the lightning in the sky

As it pass’d me flying by— 

From the thunder, and the storm— 

And the cloud that took the form  

"Alone" 

Looking up the etymology of words sometimes points out such obvious connections you never had even considered. After writing the main body of this post, I decided to look up the etymology behind the Dutch word for "lightning", and yes, of course, it does make sense the German "blitzen" is related to the word!

Mephisto is a magazine providing entertainment fiction, with a focus on mystery, but not exclusively so, as it also features stories encompassing sci-fi and other genres. It has gone through a few formats since its inauguration in 1994, and since 2021, it has become one of the perks for subscribers of the Mephisto Readers Club, being published four times a year as its club magazine, featuring serializations of for example the newest House novel by Ayatsuji Yukito, but also original stories written for the magazine. When the contents of Volume 18, 2026 Winter were first announced, my attention was immediately drawn to a new short story by Maya Yutaka: Raimei to Inazuma ("Thunder and Lightning", 2026) is a short story that will be part of an upcoming collection featuring Maya's series detective Mercator Ayu, the brilliant, but self-centred great detective who's always dressed in a neat suit and a top hat and often used as a device by Maya to address meta questions about the literary detective genre. The collection, tentatively titled Mercator Ayu no Gyakushuu ("The Insurrection of Mercator Ayu"), has no scheduled release window yet nor has it been revealed yet what and how many stories there'll be, meaning it might still be years until we see the actual book on the shelves, which is why I decided to discuss this one story early, as I really liked it.

Mercator and his Watson Minagi are staying at the Canaria Lodge, a cosy hotel near a mountain road in Okayama, three hours away from Osaka. Mercator is looking to buy some property, and preferably, haunted or otherwise stigmatized property because that's of course a lot more interesting than a normal home. His search for such a property has brought him near Tsuyama, which is why he and Minagi are taking a rest at the Canaria Lodge, which is run by Ogakie Hajime. Circumstances have left him short-handed, so he has enlisted the help of a handful of members who belong to the same club he used to be in while in university, who just have to help clean a bit, while being offered a free stay at the hotel. Mercator's quest for 'tainted property' leads to Ogakie telling about the legend of a cursed headless Jizo-statue nearby, and how he himself once saw a giant eyeball monster standing at a ridge overlooking the hotel. Mercator of course is interested in the stories, so during the day, he and Minagi go visit these sites. In the evening, they all have dinner at the Canaria Lodge, but rain and lightning cancels any plans for evening strolls. Later that evening, a decorative vase on the ground floor topples over and breaks into pieces. It's clear someone had deliberately push the vase around for it to topple over, but Mercator happened to be nearby as it happened and he didn't see the "culprit" come his way: other people in other places of the ground floor also deny having seen anyone flee the scene towards their location. They then try to ask the people upstairs, until they find one of the students is lying dead in his room, his head bashed in. Who is the killer?

Raimei to Inazuma is a pure puzzle whodunnit by Maya, who is really good constructing these puzzles, but he's also really good at playing with the format by for example taking the format tropes to ridiculous extremes, like the insanely constructed time table puzzle in Mokusei no Ouji, the brilliant set-up of having the reader guess who the victim is before they can proceed with the question of who the killer is and other such playful twists on the Queenian puzzle. Raimei to Inazuma is another fun example of Maya playing around with the format, and while some might be frustrated by the way Maya kinda ridicules the idea of a fair-play whodunnit, it works really well in this story.

In essence, the game presented here is very familiar: we know a crime has been committed, we have a rough idea of when it must have happened, so we need to identify the killer based on the actions we deduce the murderer have taken, and compare that information with the available suspects. Some of these "murderer conditions" are pretty classic ones you'll likely have encountered before in other similar pure guess-the-culprit scenarios, others are quite original: I especially like one major line of deduction of Mercator's solution, which is incredibly cleverly imbedded in the narrative of the story and basically only works because this is a Mercator story, for it would just be too outrageous for any other series detective, but in a Mercator Ayu story? Yeah, that concept goes, and it goes hard! It had me laughing out loud as I finished the story and I definitely think this was one of the best Mercator Ayu stories I've read. I have no idea how the whole collection will look like, but I already want to claim it'll be worth reading for this story alone!

Ultimately, it's just a short story though, so there's not much I can discuss about it here without spoiling anything. I don't really do posts on a single short story often, but I guess I should do them more often. Anyway, Raimei to Inazuma is definitely worth reading for the Maya Yutaka fans, or for those who want to see a mystery author play with the tropes of the genre, exploring the genre to see how ridiculous things can get if one sticks strictly to the conventions.
