I
ended the review
of Motohiro Katou's Q.E.D.
vol. 42-43 with the plan to have this series wrapped before July,
which can be done at the current rate in four twofer reviews, but
alluded to similar plans and intentions before – rarely panned as
originally intended. Going by past results, it probably would have
meant a review of vol. 50 wouldn't have materialized until January or
February 2026. I'm going to step up with two threefer reviews this
month, review vol. 50 next month and tidy it all up with part two to "The
Hit List: Top 10 Favorite Cases from Motohiro Katou's Q.E.D. vol.
1-25." After that, I'll turn my attention to Motohiro's C.M.B.
series interspersed with reviews of Q.E.D. iff. I've not
forgotten about that recommendation of the archery-themed murder case
from The Gordian Knot series. So that concludes these
household notes, unto to the review!

The
first, of two, stories from Katou's Q.E.D. vol. 44, "Tuba
and Grave," brings back the three disaster magnets of the Sakisaka
Private High School Detective Club, Enari "Queen" Himeko, Nagaie "Holmes" Koroku and Morito "Mulder" Orisato.This
time, they caused a minor uproar when mistaking a sleeping drunk, on
a park bench, for a victim of foul play with their wildly incorrect
deductions ("the suspect is possibly an alien, because we didn't
find footprints"). So the "absolute imbeciles" get
reprimanded, loose access to their club room for a week and warned
their club will be disbanded if they get involved in another
incident. Before long, those three find themselves in a
boy-who-cried-wolf situation when they witness an actual murder: a
man being strangled behind a building and his body dragged into an
abandoned factory. They decide to call-in an anonymous tip and the
police turns up with the man they recognize as the killer to open the
factory, which searched top from bottom starting with a suspicious
looking case – containing a tuba. A second, obvious place is what
looks like a makeshift grave, but only contained a visually pleasing
arranged collection of garbage. Props to the police detective for
clearing away the junk to continue digging. No evidence of a body or
crime was discovered.
So
where could the body have been hidden when the police "turned
the entire place upside down and didn't find a thing?" The
detective club, once again, turn to Sou Touma and Kana Mizuhara to
bail them out, but Touma tells them the police will figure it out
without their help ("...make sure that you behave and get the
club back"). His advice falls on deaf ears as the club goes
ahead with their own investigation and Mizuhara doing some legwork in
the background, until Touma reappears to reveal what really happened
at the factory. Touma's solution to the problem turns, what appeared
to be an impossible disappearance of a corpse, into a Columbo-style
breakdown of the murderer's alibi and ends up hanging him with his
own incriminating words.
So
a really excellent and entertaining story. Loved the cheekiness of
the method even though (ROT13)

soft spot of the Detective Club. They're absolutely useless idiots,
but they mean well.
The
second story from vol. 44, "Questions," is one of those
puzzles-with-a-heart that are scattered across this series. Touma
receives a cryptic invitation to a getaway at a luxurious villa. The
invitation is a card with the word "QUESTION" on the front and
Fermat's Last Theorem on the inside. And he was not the only one to
receive an invitation. Several people going through a divorce have
gathered at the villa with similar, cryptically-worded invitations.
What follows is basically a cross between a treasure hunt and
personal journey's of rediscovery. Touma primarily functions as a
sideline oracle giving mini-lectures on mathematics, history of
mathematical ideas and "an ever-expanding universe of numbers"
("...didn't understand a thing...").
A
decent, if not particular memorable, entry in the series and Katou
has done better puzzles-with-a-heart stories before. However, the
ending admittedly made for a nice finishing touch to this
character-driven story.The
first story from Q.E.D. vol. 45, "Venus," is a somewhat
off-beat whodunit. Himichi Sayaka, a second year college student, is
arrested on suspicion of having killed her ex-boyfriend, Mizushima
Takuya – a third year student. Mizushima Takuya was found beaten to
death in his apartment with door and windows securely locked from the
inside, however, Himichi Sayaka has a spare key. She was seen near
the apartment at the time of the murder and a bloodied baseball bat
was discovered behind her own home. They had been fighting over money
he owed her. So the prosecution can prove means, motive and
opportunity, but the prosecutor has her doubts and asks Touma to see
if he can spot a frame job. Mizuhara remains perplexed important
people keep asking Touma for help ("but... this guy is still in
high school"). If she has been framed for murder, the crime
becomes an impossible one.
This
story is, strangely enough, interspersed with comic-y vignettes in
which a Venusian space girl, named Serge, teaches a talking raccoon
in dungarees about the solar system. I really liked the one panel
blending the retelling of how the murder was discovered with a floor
plan of the crime scene. Some artistic touches that helped to make it
stand out and cushion two notable short comings: a murderer who
suspiciously stands out and a surprisingly routine locked room-trick
for this series. That being said, the conclusion is solid enough with
Touma eliminating all but one of the suspects before trapping them
with their own words ("...something only the murderer could have
known..."). A fair effort.
The
second story in vol. 45, "First Love," can be read as an
improvement on the previous story. Koba Tomotoshi is pretty average,
second year student at Sakisaka High School. And to his very great
surprise, Nitobe Rena asked him one day to be her boyfriend.

Nitobe
Rena is the beautiful, popular girl at school and their relationship
painted a target on his back. Something happened some time later when
he took her back to his house and barely inside, they hear a thump
coming from the balcony. What they find on the balcony is the body of
a fellow student wrapped inside a bag. So how did the body end up on
the balcony? It couldn't be a bizarre suicide, because the apartment
is on the seventh floor of a twelve floor building and the body would
have landed on an upper apartment balcony. Since this incident,
Nitobe's parents have forbidden to see Koba. In desperation, he turns
to the teenage genius and classroom detective of his school. Touma is
currently engaged on, what they call, the Rakugo Artist Case.
Mizuhara gets to play detective, collect evidence and contribute a
pretty solid false-solution to the story. I had the most fun with
this story playing armchair detective. I had a good idea about the
who and why, but was stumped by the how. Something I should have
figured out, but somehow missed entirely. Yes, I can be very dense at
times, but well played regardless!The
first story from Q.E.D. vol. 46, "Broken Heart," is the
Rakugo Artist Case and is one of those stolen money stories Katou has
done before, but this one has a neat and original wrinkle on the
classic locked room situation. The setting of the story is the comedy
theater Shitamachi where the princely sum of five million yen is
stolen from the senior Rakugo artist, Tsubakiya Kamekichi, who
brought the money along for safekeeping. And to ensure its safety
during the performance, the money was locked inside a wallet with
padlock secured to the handle of a steel ornamental jar. Only to
discover later that evening the stacks of bills had somehow been
replaced with blank paper! So how was the money taken from the locked
wallet? The locked wallet-trick is only a relative small part of this
character piece with its theatrical backdrop and backstory of young,
aspiring actress/comedian/narrator, but just loved the visual imagery
of the locked wallet hanging on a jar.

You
don't find that many impossible crime novels or even short stories
fiddling around with padlocks, because you have to ignore the fact
they're not all that reliable and easily picked open. Suppose the
same holds true for this story and the possibility alone should have
made the person watching over the jar the primary suspect. Just going
with the story, Katou demonstrated yet again you can achieve great
effects with relatively simple, straight forward tricks. Loved it!For
those sick and tired of me droning on about locked rooms and alibis,
the next story is for you. "Pilgrimage" is probably the darkest,
most disturbing story this series has told and has Touma
reconstructing a long-forgotten, deeply buried secret dating back to
the Second World War. The story begins in the present with Uchibori
Koyuki, a proof reader, finding an unpublished manuscript written by
her late father, Shoichiro, who was a non-fiction writer. Manuscript
is titled Pilgrim and has three handwritten notes on the
cover, "rejected," "coincidence?" and
"intentional?" Why was it rejected and shelved? She shows
the manuscript to Touma and he found the subject matter more
interesting than the reason why it was rejected. Pilgrim tells the
tragic story from the early 1940s of a serial robber who accidentally
killed one of his victims, a young newlywed woman, which forced him
to flee the country. Yamai Seimei was eventually captured in Hanoi,
Vietnam, ensuring "the bastard will get the death penalty."
Usui Shigeru, victim's husband, travels to Hanoi under wartime
circumstances, but halfway through he decides to continue the journey
to Hanoi on foot – about a 1000 km journey. Two months later, Usui
Shigeru arrives at the court in Hanoi and asks the court to spare his
wife killer by commuting his death sentence to a prison sentence. But
why? More importantly, why was it not enough to save the killer from
death? And, of course, the reason is also why the manuscript remained
unpublished.
A
very dark, disturbing reason. Not that you would get that impression
from the description, so far, because “"Pilgrimage" starts out
with a human touch of Chestertonian wonder. A man forgiving and
sparing the life of his wife's murderer following a mysterious,
self-imposed pilgrimage and the wonder what he could have experienced
during those two months. Only for it to turn in a terrifying,
pitch-black and nightmarish horror plucked from the pages of an Edgar
Allan Poe tale. Or, in this case, Edogawa Rampo. Bravo!
So,
on a whole, not a bad collection of stories covering these three
volumes. "Tuba and Grave," "First Love" and "Pilgrimage"
are the obvious standouts and personally liked "Broken Heart" for
its locked wallet mystery. Only "Question" and "Venus" trailed behind, but even they had their moments. Far from
disappointed and look forward to the next three volumes, which you
can expect before too long.
