What goes up must come down
(English proverb)
With a noticable draught in new Detective Conan releases last year, I resorted to checking out some of the anime episodes which were not based on the Detective Conan comic source material, but original stories created especially for the anime series. I picked out a few episodoes which are often praised as good mystery stories. Stories like Dracula-Sou Satsujin Jiken and Meikyuu he no Iriguchi - Kyodai Shinzou no Ikari were indeed better than the usual anime original episode, but the special Noroi no Kamen wa Tsumetaku Warau and the three-parter Koureikai W Misshitsu Jiken were far more than that and easily made it into my list of favorite mystery fiction of the year, being excellently locked room mysteries and more importantly, master classes in how to properly plot a mystery plot with synergy between the story and the core mechanics of the mystery.
Ran has won a sightseeing tour to Izu, Shizuoka Prefecture by solving a puzzle in a magazine (actually, Conan was the one to solve it), so now she, her father Kogorou and Conan are enjoying the nature there. In the mountains near their ODA Hotel stands the 400-year old Genkaiji Temple and the three learn of several legends involving the temple. For example, there's a dried-up well in the back that supposedly dried up suddenly when in the Edo period, a woman with love grief cried her eyes out in front of it for three whole days and nights. Another legend involves the five-storied pagoda on the temple grounds. In the past, an abbot-in-training tried to elope with someone in the village, but he was swept away by an eagle and he was found hanging from his neck from the pagoda. Another abbot sold valuables from the temple, but he too was found hanging from the top floor of the pagoda after several days of disappearance. It is thus thought people who defy the temple are subject to divine punishment, which the current abbot of the temple, Tankai, believes will also occur to Oda Hideaki, head of ODA Tourism. According to the abbot, Oda swindled him out of the property rights of the land of the temple, and now Oda plans to use the extra ground to build a theme park. Back at the hotel, Kogorou is invited to join Oda Hideaki for dinner, as having the famous Sleeping Detective stay at the hotel means great marketing, but the following day, Kogorou is shocked to learn that Oda was found hanging from a rope from the highest floor of the five-storied pagoda. With quite a few enemies in his life, it is first suspected this is murder, but both Kogorou and the police soon stumble upon a major obstacle. Oda was quite a portly man, and nobody could've carried his body, alive or dead, five stories up without messing up his clothes or leaving any distinctive marks on either the man himself or the pagoda. It thus seems Oda must've hung himself out of his own will, but that too seems unlikely psychologically, so the only explanation left is... divine punishment?
Nah, Conan has a far more rational solution ready, of course. The suicide theory is also soon proven to be unlikely, as the rope hanging from the eaves of the pagoda wasn't long enough to allow Oda to stand on the balustrade to hang himself, but the problem still remains that it's equally impossible to get Oda up to the highest floor of the pagoda alive to hang him there, especially not without leaving any tracks. The theme of this story is likely to remind of the story in volume 11, which also featured an impossible crime in a Buddhist temple. I reckon that the core idea of how Oda's body was brought up to the top of the pagoda can be guessed pretty easily, even if some of the details might be a bit trickier (there's an interesting part with that involves the rope with which Oda was hanged, but it leaves less of an impression compared to the main trick). It's an impossible crime trick that works quite well in this particular format, even if it's also a bit silly, but it's also so straightforward, it doesn't really needs two episodes. And that is definitely one of the problems of this story: had this story been featured in the manga, it would've taken three chapters and been turned into a single episode. Now it's spread really thinly across two episodes which feel slower than they should be. The mise-en-place of the clues and suspects is functionable, but it's certainly not a classic like Noroi no Kamen wa Tsumetaku Warau.
And the whodunit aspect of this story... well, it's there. But the clues to their identity are far too obviously inserted in the story and almost feel like an afterthought, as if the whole impossible crime part came first, and then the scriptwriter realized he should probably also add some clues that point to the culprit too, and not just to how the crime was committed.
Kaiki Gojuutou Densetsu is perhaps not one of the best anime original episodes, but the core impossible crime is kinda amusing to watch and compared to other anime originals, this is still a fairly decent one that is strictly focused on its mystery plot. While I think two episodes is far too generous, there are some minor twists regarding the details of the crime that give the viewer still something to think about even if it's likely they'll (partially) guess what went on. If you have already seen the same anime originals I saw last year, I think these two episodes follow in the same spirit, even if they are also clearly not as phenomenal.
