I started reading Motohiro Katou's Q.E.D. in 2018 and over the years, despite some prolonged hiatuses and ill-fated restarts, it not only became one of my favorite manga mystery series, but one of my favorite detective series in general – regardless of medium or form. A new kind of traditional detective story for the 21st century and should have finished it years ago, because you would think the locked downs from a few years ago would have helped. But no. Well, I promised to have this series done, dusted and in the books before summertime rolls around. And here we are with time to spare.
Fittingly, I'll end this run how it started with a single review of the last volume. The last two stories from Q.E.D. vol. 50 present not only a return to form, but feel like a return to the stories from the earlier volumes with one subtle little difference. Sou Touma and Kana Mizuhara look slightly older than they were at the beginning of the series.
The first story of Q.E.D. vol. 50, "Observation," draws on Sou Touma's time as a teenage prodigy at MIT where he met another young genius, Sally Blythe. Years later, she has become the head of a company manufacturing instruments for observational experiments, "Blythe Inc. is pretty famous," but her company is being targeted by, what can only be called, an invisible enemy – who carries out seemingly impossible acts of sabotage globally. Providing the story with some recognizable and famous backdrops. First stop is the Large Hadron Collider, on the border between France and Switzerland, where an unknown intruder switched switched off the flow of liquid helium forcing a shut down. However, the intruder was caught on the CCTV and surrounded by two groups guards inside the circular tunnel. When the two groups bumped into each other, the intruder simply had vanished without a trace! A second and similar act of sabotage occurred at the Mauna Kea Observatories, in Hawaii, where the cooling process was interrupted during an observational experiment. But how did the culprit managed to tamper with equipment that had been securely locked and sealed away for ten days? The saboteur strikes again at the Kamioka Observatory in Japan by placing radioactive radium ore beside an underground detector.
Sally Blythe turns to Sou Touma and Kana Mizuhara to not only help figure out how the culprit managed to sabotage their experiments, but who's behind it all and why. So we get a nicely-layered, intelligently plotted detective story and human touch to the characterization. Not black and white or shades of gray as exemplified by the ending, which is neither a happy ending nor a depressingly dark conclusion. Just something human under less than ordinary circumstances. I really enjoyed the various impossible situations perhaps showing the influence of MORI Hiroshi and novels like Tsumetai misshitsu to hakase tachi (Doctors in the Isolated Room, 1996).
I
think most of you already have a pretty good idea how the saboteur
disappeared from the LHC. You would be particle
partially correct, however, Katou pleasantly elaborated on that basic
idea to create something more fitted for its special setting. The
locked room-trick at the Mauna Kea Observatories is far more
original, but not easily solvable for your average armchair
detective. Even with a devious hint to its solution being dropped in
your lap. Despite it being somewhat of a specialized locked room, I
really liked it and appreciated its novelty. The sabotage at the
Kamioka Observatory is not really a locked room problem, but serves
another well-done purpose to the overall plot. So an all-round
excellent opener to the final volume!
The second and last story of Q.E.D. vol. 50, "Escape," reads like a season finale adding thrills as frills to a good, old-fashioned and cleverly contrived locked room mystery.
"Escape" opens with a flashback, "16 years ago," to a warehouse used by an unnamed child as a secret hideout to read his favorite adventure series, Adventures of Brave, the Knight, but, one day, an intruder enters the barn – casually stringing up a body before leaving. This intruder leaves the barn locked from the inside with a padlock. The child disappears from the barn just as mysteriously, but not before taking the ring from the hanging body. So the police at the time are confronted with what appears to be a suicide inside a locked barn. So the case grew cold and was forgotten, until Sou Touma and Kana Mizuhara receive an anonymous request and money to organize an Escape Room game. A game organized for the benefit of a small party made up of an ex-policeman, a fortune teller, a food sales executive, a mangaka (manga author) and a part timer.
All five received a personal invitation to take part in the game with an opportunity to win one million yen, but the mini-puzzles prove to be too cerebral for the participants. Suspicion rises when items like an old ring and a copy of Adventures of Brave, the Knight turn up in the game. And, eventually, the game becomes a dangerous one as they find themselves locked inside the labyrinth with a time bomb counting down the minutes they have left to escape. Even though it has been done before, the reason behind staging the escape game is still very clever indeed and wonderfully presented/executed through the escape game setup.
The solution to the locked room murder from 16 years ago deserves a special mention, because the trick offers something entirely new when it comes to impossible crimes in padlocked rooms or buildings. I'm sure I mentioned this somewhere before, quite recently, but the reason why padlocked rooms are even rarer than "taped tombs" is because padlocks are too unreliable, and too limited, for a proper locked room mystery. They're wide open to being picked, replaced or swapped around. So you won't find much scope or depth in the trickery in the, what, half a dozen known examples. That makes the locked room-trick here so refreshing and surprising, because it found a new way to get out of padlocked room.
I should also note here Touma has very little to do here, except help setting up the escape room and act as an impartial observer as the plot unfolds itself. Typical for this series to give its protagonist a passive role in its closing act. Nothing to detract from this splendid and fun locked room thriller. So, overall, a very strong volume to end this series on. Somewhat of an open ending, perhaps, to the series and characters, but this is, of course, not the end of the road for Sou Touma and Kana Mizuhara – both of whom will return in Q.E.D. iff. I look forward to digging into that series, but first have to begin slapping together part two of "The Hit List: Top 10 Favorite Cases from Motohiro Katou's Q.E.D. Vol. 1-25." I'll probably take a palate cleanser before returning to C.M.B. and starting on Q.E.D. iff, which might even include a return to The Kindaichi Case Files. Stay tuned!
