I
reviewed
the first volume, of fifty, in Motohiro Katou's Q.E.D.
series back in 2018, reached the halfway mark (vol. 25) in May 2023
and posted "The
Hit List: Top 10 Favorite Cases from Motohiro Katou's Q.E.D. Vol.
1-25" a few months later – intending to have part two up by
the end of 2024. You know how it goes with even the most vaguely
stated, flexible of "deadlines" on this blog. I'm a
traditionalist, if there ever was one. That being said, if my track
through the first-half of this series was done at a snail's pace, the
second-half was a sprint to the finish. Only a little a year and a
half to get from vol. 26 to vol. 50. So not bad by my standards!

I
reached vol. 50 last month and having reviewed every volume in
addition to several specials,
crossovers
and sampling its sister series, C.M.B.,
Katou and his cast of regulars hardly need an introduction. Neither
do I need to go over the points on why I started calling Q.E.D.
the detective story for the 21st century. I have regurgitated all
that over, and over, again in previous reviews. Just read the top 10
vol. 1-25 for a short introduction. I'll take a moment to go over the
selection process.This
time, picking ten favorites was not as easy as the first time. I
simply started compiling a list to whittle down to ten stories, but
ended up with seventeen stories and kept moving them around between
the candidate list and the final list – every story made the top 10
at one point. I wanted the list to reflect the scope of variety
across this series. One thing I rarely mentioned is how Q.E.D.
found a way to combine the advantages of a long-running series
(familiarity) with the creative freedom afforded by standalones. So
the stories and plots cover everything from traditionally-plotted
whodunits, impossible crimes and alibi crackers to character
explorations, slice-of-life mysteries and down right experimental
fiction. And pretty much everything in between. You know me...
there's always the risk I'll jump on my hobby horse and do a "Top
10 Favorite Locked Room Mysteries & Impossible Crimes from
Motohiro Katou's Q.E.D.," but managed to keep temptation at bay. I
think I weeded out a fairly representative top 10 list from my
original seventeen picks, which get an honorable mention at the end.
Even if they didn't make the final cut, they're still technically top
10 material.
Before
tumbling down the top 10, I want to assure those who don't care about
Katou, Q.E.D. or manga mysteries in general, you'll be getting
a break from them after this one. I don't think I'll get to Gosho
Aoyama's Case Closed, vol. 94 until sometime next month.
I'll pick something a little different as a palate cleanser, before
returning to C.M.B. or starting with Q.E.D. iff. So
with all that poorly done blog-padding out of the way, let's begin.
"Summer
Time Capsule" (vol.
26)
The
first entry on this list appears on first sight to be minor stuff, a
slice-of-life mystery, centering on a time capsule unearthed by
construction workers with Kana Mizuhara's name on the lid – buried
during her primary school days. Mizuhara's memories of her primary
school days have already become hazy and the contents of the capsule
poses a big mystery to her. Such as a group photograph with a kid
neither she nor her friends remember. Mizuhara begins to suspect she
might have done something very bad. Not to mention a mini-puzzle
hidden inside the narrative. Where the story sets itself apart is
using a simple, innocent childhood mystery to show how time ravages
the memory, because you can't recall every single second of your
life. So you leave more of yourself in the past than you take into
the future. As an anonymous comment on my review pointed out, "Summer
Time Capsule" is one of the best human drama mysteries in this
series.
"Motive
and Alibi" (vol.
29)
This
second entry represents Q.E.D. at its most traditional and
conventional, but an absolutely first-rate, classically-style
whodunit. Sou Touma becomes involved in the murder of a celebrated,
award winning painter, Kuromame Fukuzo, who's murdered at his home
surrounded by three potential suspects. Only problem is that they
possess rock solid, unshakable alibis. The murderer has every reason
to be confident in their alibi, but Touma spotted a contrived set of
circumstances that created a "golden window of opportunity"
for murder. Even better than the ingenious and original alibi trick
is how Touma's explanation built on Inspector Mizuhara's evidence and
bare-bones solution. I like it when the brainy amateur and
experienced, casehardened professional actually compliment each
other.
"Magic
& Magic" (vol.
32)
Similar
to the first entry, "Magic & Magic" is one of the best
character-piece this series has to offer and my personal favorite.
Kurohoushi Manto, a magician, overhears Touma explaining his tricks
to Mizuhara during a performance and proposes a challenge to the
teenage know-it-all – wanting an opportunity to genuinely surprise
Touma. A wonderful story full with magic tricks and the seemingly
impossible disappearance of a book from a locked and guarded safe.
However, the locked safe trick and magic trick is not the main draw
of the story, but Manto's demonstrating there's a small, essential
difference between fooling someone and surprising them. Bravo Katou!
"The
Detective Novelist Murder Case" (vol.
33)
A
return to the traditionally-styled detective story centering on a
group of four published mystery writers discussing a plot idea for
the perfect crime, a murder disguised as a domestic accident, but
how's the murderer going to leave the scene locked from the inside?
Someone obviously found an answer when one of them dies in exactly
the same circumstances as they discussed and examined. Only
difference is that all the doors and windows were found locked and
securely fastened. What makes this story standout is the elegant,
brilliant simplicity of the original locked room-trick and Touma not
only revealing who, why and how, but also showing why the other
suspects couldn't have done it. A detective story with a high purity
plot!
"Christmas
Present" (vol.
35)
Despite
the story title, "Christmas Present" is not a seasonal mystery
with the December festivities serving as background decoration for a
clever piece of genre parody, playfully poking the shin honkaku
mystery in the ribs – staged and presented as mock theatrical
mystery. The notorious Detective Club of Sakisaka High School helps
out making up the numbers of the Drama Club to prevent their
Christmas Show from getting canceled, but under condition they stage
a mystery play. Touma and Mizuhara naturally get put to work with the
former having to write a script on the spot. Touma comes up with
Murder at the Pentagon House about a murder in a small,
pentagon-shaped house with the door and windows locked on the inside.
While being tongue-and-cheek, the locked room-trick is actually quite
clever and original. A trick that can actually be used in a comedy
mystery play. So really fun and successful parody of the shin
honkaku mystery.
"The
Incident in Urban Hills Room 6" (vol.
39)
I
constantly moved this story back and forth between the candidate list
and the final list, before deciding to keep it in the final ten. This
story takes place at a shabby, rundown lodging house where the
landlady was found hanging in the titular room, dismissed by the
police as a suicide. But left the place with a stigma as nobody
wanted to apply for the job of housekeeping. One day, Mizuhara
appears on their doorstep to take the position and immediately begins
to asking questions, which she relies to Touma playing armchair
detective in the background. However, this story is not nearly as
conventional as it sounds and, like said in my original review,
somewhat of an anti-detective story that's not really an
anti-detective story at all. I really liked how Touma showed none of
tenants have a motive only to turn around and show why one of those
non-motives is a motive for murder.
"Secret
Room No. 4" (vol. 40)
This
entry undeniably is dictated by my personal obsession
taste for locked room mysteries and every other kind of impossible
crime fiction under the sun. Touma, Mizuhara and the members of the
Sakisaka High School Detective Club partake in a test run for murder
game, based on the works of a well-known mystery novelist, on behalf
of the tour company – which brings them to the perfect setting for
a murder, Sasakure Island. A game consisting of various locked room
puzzles challenging the players to find out how the crime was carried
out, not whodunit or why. Not unexpectedly, the test game is
interrupted by an actual locked room murder. There are a total of
four locked room mysteries in this story and an argument can be made
Touma's solution revealed a fifth, neatly hidden, impossible crime.
While not all the locked room-tricks carry that brand new car smell,
they're brilliantly employed together to create a special treat for
impossible crime fans like me.
"Tuba
and Grave" (vol.
44)
The
three disaster magnets of the Sakisaka High School Detective Club
again get themselves into serious trouble when they foolishly mistook
a sleeping drunk for a murder victim with their wildly incorrect,
ludicrous deductions. So they find themselves in a boy-who-cried-wolf
situation when witnessing an actual murder and the body being hidden
inside an abandoned, rundown factory. They call in an anonymous tip
to the police who search the place from top to bottom, which include
a freshly dug, filled-in hole and a tuba case. No murder victim is
discovered. So they turn to Touma and Mizuhara to help them out of
another hole. A really fun story, but the plot is great as well with
an even better conclusion. Touma basically turns what appears to be
the problem of an impossibly disappearing body into an inverted,
Columbo-style breakdown of the murderer's alibi and trapping
the killer with incriminating knowledge.
"Pilgrimage" (vol. 46)
Q.E.D.
is not exactly a cozy mystery series, but neither is it excessively
dark or disturbing and tends to find a happy balance between the
darker and lighter sights of life. Usually done in colors rather than
shades of gray. Not this unsettling, pitch-black story centering on a
long-forgotten incident dating back to World War II. A forgotten
incident rediscovered inside an unpublished manuscript from a dead
non-fiction author with some cryptic words scribbled on the cover.
Why did the husband of a murder victim traveling to Hanoi, under
wartime to conditions, to confront the murderer court decided halfway
through the journey to continue on foot? Why did he, following a
track of 1000 km on foot, arrive at the court two months later to
asked the court to spare his wife's killer by commuting his death
sentence to a prison sentence? Why did it fail to save the killer? A
story deceptively starting out as a human interest story with a dash
of Chestertonian wonder, but the ending revealed a nightmarish horror
plucked from the pages of of an Edgar Allan Poe or Edogawa Rampo
tale.
"Escape"
(vol.
50)
I
realize I should have swapped this entry with any of the honorable
mentions listed below, but enjoyed vol. 50 too much to not include
one of its two stories. I decided to go with "Escape" over the
global spectacle that's “Observation,” because enjoyed the former
slightly more. A fun combination of the locked room mystery with a
mystery thriller. Touma and Mizuhare receive an anonymous request and
money to organize a private escape room game for a small group of
people, but the participants soon find themselves trapped inside as a
bomb is ticking down the minutes. This situation is tied to an
unsolved, sixteen year old locked room murder dismissed at the time
as a suicide. Three things make this story standout: the reason for
staging the escape game, the original locked room-trick for a
padlocked door and a plot unfolding itself through the escape game.
Touma and Mizuhara have little else to do other than being impartial
observers. Leave it to Katou to find a way to be unconventional in a
conventional locked room mystery.
