Following
a short hiatus, I returned to the work of Motohiro
Katou back in September with a review of C.M.B.
vol. 5-6 and the intention was to have gone through the first ten
volumes, before the end of the year, but just noticed I forgot to do
C.M.B. vol. 7-8 last month – having reviewed
Gosho Aoyama's Case Closed, vol. 95 in October. So guess you
can call that a return to tradition.
Katou's
C.M.B. vol. 7 differs from previous volumes in both the C.M.B.
and Q.E.D. series, which normally contain two longish stories
or occasionally a single long story (e.g. C.M.B. Vol.
4), but Katou this time tried his hands at four shorter stories.
So the plots and storytelling tend to be smaller in complexity and
scope than the longer stories. The result's as mixed and varied as
the stories themselves.

"Locust" is the first of these four shorter stories and best described as an
ecological mystery-thriller, of sorts, which takes place in one of
those remote, mountainous villages named Yamanomizu – plagued and
torn by several divisive issues. First of all, the village is divided
over the plans to build a road to bring government money to the
village and province, but half the village opposed the plans because
they "feared that the forest would be torn down." Secondly, the province where the village is located has a plague of
locusts and in three days, "the village and their crops will be
attacked by the locusts." So the villagers in favor of the road
want to spray everything from the fields to the forest with
insecticide ("...going to be torn down anyways"). Thirdly,
local children spotted a rare, beautiful bird in the forest, "never
seen before," but nobody believes them. One of the kids heard
of Sakaki Shinra, curator of Shinra's Museum of Antiquities, who
takes Nanase Tatsuki to Yamanomizu. Shinra has a pretty good idea
about the bird, but seems more interested in the locusts and, of
course, someone tries to protect money making road project to give
the story a mild touch of the thrillers. Not much of a detective
story, plotwise, but the backdrop allowed for a few good, nicely
drawn scenes towards the end.The
second story, "Iron Door," is a different story altogether! Mau
Sugal, the black market broker, returns to the Museum of Antiquities
to take Sakaki Shinra and Nanase Tatsuki along on an unusual treasure
hunt. She brings them to an abandoned factory with a once buried, now
excavated bunker doubling as an army research laboratory during the
Second World War. This leads to a long, dark passageway with a huge,
heavy steel door at the end. A door that used to be opened with a
motor, but the motor was destroyed when the place was closed and
sealed. So now it takes the combined effort of three, or more, people
to open it. Mau believes "there's some treasure behind this
door," but she needs the other two to help her pry it open.
When they do, they find an empty storeroom with the fresh corpse of
an elderly man inside, 81-year-old Gomoku Shigetsuga. He turned up
shortly after the place was excavated and unsealed to claim the place
couldn't possibly be empty.
So
while "Iron Door" is as long, or short, as "Locusts," it's a
much denser story with a packed, nestling doll-like plot – stacking
mystery upon mystery. Who trapped and killed the old man? How did the
murderer opened, and closed, the door without help? What did the
victim know about the wartime secrets buried in the bunker? And what
happened to those secrets? Is there still something hidden in the
bunker that the police overlooked? How does Mau figure in this case
and why did she leave cartoon smoke after discovering the body? The
answers to all these questions nicely dovetail together with the
unusual impossible crime situation making it standout, but even
better than the original, quasi-inverted take on the locked room
mystery is the clearly written, cleverly hidden dying message. Maybe
the best use of the hidden dying message since the Columbo
episode Try and Catch Me (1977). The best story of the volume!
The
third story, "In the Civic Pool," is not necessarily bad, but it
has a threadbare plot and a very forgettable story. Tatsuki takes
Shinra and some of her classmates to the public swimming pool where
they become entangled in a series of mini-mysteries involving missing
concert tickets, a water beetle supposedly "extinct in Tokyo" and figure in the swimming pool who disappears like a ghost when
looking in its direction. All very simple mysteries with simple,
straightforward answers. Only thing that really stood out is Shinra
taking care of the water beetle, but other than that, Katou still has
to figure out how to translate his trademark character-driven,
slice-of-life puzzles to the one-chapter story format.
This
volume ends on a high note with a pleasingly conventional mystery,
“The Turk,” which is the famous chess playing automaton that
toured and enraptured Europe in the 18th century. A replica of the
Turk is currently part of Tagame Tatsuo's collection of antique
“mechanized puppets” and Shinra, holder of the "C," "M," and "B" rings, has full access to the collection for his
research – even gets to play to play the celebrated automaton.
During their round of chess, the automaton fails while a robber
smashes a display and gets away with three valuable puppets. Shinra
promises to get back the antiques in exchange for the replica of the
Turk. So the solution appears to entirely hinge on breaking down the
alibi of the person who operated the automaton. Shinra reminds
everyone the Turk is "not a mechanized puppet," but "more
of a magic trick." Like I said, a pleasingly conventional
detective story.

By
the way, I liked Tatsuki's false-solution infusing the 18th century
illusion of the chess playing automaton with modern technology.Katou's
C.M.B. vol. 8 continues the format of vol. 7 with four
shorter, one-chapter stories and the first story is “One Hundred
and Thirty Million Victims.” Detective Inspector Takeshi receives a
picture of an ant-lion accompanied by threatening letter promising
that, "on November 6th, at 6 PM, I will enact my revenge. The
130 million people of Japan will be the victims." Takeshi
goes to Shinra to use him as a soundboard and, pretty soon, a lead
presents itself. A man by the name Yoshikawa Masahisa was arrested
and convicted for a disgusting crime: robbing a young mother and
kicking over the baby carriage, which injured the baby. So the media
and public came down like a ton of bricks on him and his family.
However, the real culprit was found years later and Yoshikawa
Masahisa was released from prison without a word of apology from the
media and public. The story is about trying to prevent someone from
taking revenge, however, the ending showed that not everything is as
it seems. A prescient ending at that for a story originally published
in 2008 (likely had a magazine appearance in 2007). A good opening
act!
"A
Meteorite" is the second and my personal favorite story from this
volume. Shinra travels to the Baikonur Cosmodrome, a Russian operated
spaceport in Kazakhstan, where "something cumbersome" crashed nearby and created a giant crater – a large meteorite.
There are, however, two problems. Firstly, the representatives of
Kazakhstan and Russia both stake claim the meteorite. Secondly, the
meteorite itself has impossibly disappeared without a trace. Not only
the meteorite has disappeared, but they couldn't find a bit of debris
or single fragment of it at the impact site. Someone, somehow,
cleaned out the entire site in a mere three days. And, given the
circumstances, that's a Herculean task. What a great and original
premise! Shinra also has to take a well-known meteorite hunter and
the locals into consideration when answering these questions and
arbitrate the outcome. Yes, the explanation how the impact site was
cleaned out is as clever as it's cheeky. Simply a good, fun and
original mystery.
The
third story of this volume, "A Strange Tale from Kushino Mura," gets a little experimental. This story finds Shinra and Tatsuki on a
skiing holiday, but, where the ski resort stands today, once stood a
mountain settlement, Kushino Village. Shinra naturally gets
interested in the backstory of this forgotten village and an old man
tells them to visit the shrine, if they want to know more. A shrine
dedicated to the cats that once saved the village and a faded
backstory, barely legible, written on the wall mentioning demonic
possessions, deaths within three days and a husband and wife ("...one
of them died"). A short time later, Shinra and Tatsuki get
caught in a blinding snow storm, on the advanced trail, that somehow
flings them back into the past. On the day when Kushino Village was
born into tragedy. So they have to figure out the source of the
original tragedy to prevent another, but what gave the story a real
chill is when Shinra realizes the truth behind their time-slip
adventure (ROT13: n
gvzr-ybbc va juvpu crbcyr “ercrngrqyl qvr, sberire”). Not
exactly a classically-styled detective story, but this one is more
about storytelling than laying out an elaborate plot. I enjoyed it.
On
a side note, "A Strange Tale from Kushino Mura" is not the first
time-slip mystery to feature in Katou's detective fiction. "The
Legacy of the Sage," from Q.E.D. vol.
19, transports Kana Mizuhara from 2004 to 1927 where she meets
Sou Touma's historical double.
"The
Statue of a Male Goat" is the fourth, and final, story from this
volume. Shinra is drawing plans, in class, to redo the layout of his
museum and he has the resources to do it ("...already hired a
moving company"). Meanwhile, the owner of small, struggling
moving company is offered a big sum of money to swap the titular
statue from the museum's collection for a replica, but stealing from
Shinra is not as easy as taking candy from a baby. Another fairly
minor story, but always welcome a return to Shinra's museum.
So
these eight stories from C.M.B. vol. 7 and 8 present the
proverbial mixed bag of tricks. "Iron Door" is the obvious
standout and my favorite for boringly predictable reasons with "The
Turk" and "A Meteorite" following close behind. I liked "A
Strange Tale from Kushino Mura," but more as a historical flight of
fancy with criminal intent than as a proper detective story and "One
Hundred and Thirty Million Victims" has a memorable conclusion. "Locusts" is mostly scenery, "In the Civic Pool" and "The
Statue of a Male Goat" give little to comment on. Not bad, on a
whole, considering Katou switched from longer to shorter stories as
none of the stories are bad, but some work still needs to be done.
I'm curious to see how Katou is going to continue these short,
one-chapter stories in C.M.B. vol. 9 and 10 next year.
