The Crimes in Cabin B: Case Closed, vol. 78 by Gosho Aoyama

The 78th volume of Gosho Aoyama's Case Closed, originally published as Detective Conan, which has the longest story since vol. 58 that was setup in the previous volume and covers seven chapters with the second, three-chapter story acting as its aftermath – while the last chapter sets the stage for the return of Kaitou KID. A return alluded to in the opening chapter as KID's long-time nemesis, Jirokichi Sebastian, announced he was planning to use the Mystery Train to exhibit "one of his rare gems." Somewhat of a baited trap, as usually, but more on that in a moment. 

The Bell Tree Express is the "Mystery Train," owned by the Sebastian Conglomerate, which hosts an annual murder mystery game with "no stops until the final destination." A "murderer" and "victim" are chosen at random from from among the guests with the other passengers playing detective and "try to solve the mystery before the train reaches the station."

Anita presented Conan with a Mystery Train Pass Ring in the previous volume to lay the groundwork for a truly special kind of detective story. A story that succeeded in being both a classically-plotted, baroque-style mystery with no less than two impossibilities and a character-driven thriller with a galore of recurring characters and some major plot developments.

Firstly, the murder mystery game begins early when Conan and the Junior Detective League receive a note telling them they've been selected as the detectives and to follow instructions, namely visiting "Cabin B of Carriage 7 in ten minutes," where they witness a shooting – turning the murder mystery into "a game of tag" with the fleeing assassin. But when they meet one of the conductors, he tells them the mystery game is scheduled to begin in about an hour. So they rush back to Cabin B, which is when they make a startling discovery. Carriage 7 has "disappeared from a moving train" along with the victim in Cabin B!

Conan only needs a handful of pages to solve the impossibility of the vanishing train carriage, but the reappearance of Cabin B presents him with another miraculous murder. This time, the victim is actually dead with a very real bullet in his head, but the cabin door was "chained shut" from the inside and the conductor in the corridor "didn't see anyone enter or leave the cabin." A seemingly impossible murder in Cabin B begs to be compared to John Dickson Carr, but the story is unmistakably a clever and warm tribute to Agatha Christie's Murder on the Orient Express (1934). There are many nods and winks to the story and Aoyama very effectively recreated a well-known scene for his own ends. Most amusing of all is Richard Moore badly imitating Hercule Poirot throughout the story and he barely broke character.

However, the story is not merely a lighthearted sendup of Christie's Murder on the Orient Express as the plot is quit good. The locked room-trick is a clever combination of simple trickery and elaborate misdirection strengthened by some good clues like the defective light above one of the cabin doors.

So the puzzle-side of the story is absolutely solid and a first-class specimen of the railway mystery, but there's a darker, parallel story taking place in the background involving a ton of recurring characters and agents of the Black Organization.

Black Organization received intelligence Anita, or "Sherry," is traveling on the Bell Tree Express, "a steel cell on wheels," which means the hunt is on and they intend to "flush her out like a deer" – catching a bullet as she leaps out. The opening pages revealed "Bourbon" is tasked with hunting down and eliminating Anita, but his, or her, identity has never been revealed. And, as to be expected, more than one familiar face has boarded the train who can all be the mysterious Bourbon. What follows is dangerous and explosive battle-of-wits crossed with a game of hide-and-seek, while Conan is busy investigating the impossible murder in Cabin B. A very well-done and handled piece of storytelling that not only added an extra dimension to the regular murder investigation, but furthered the ongoing story-arc and revealed the identity of Bourbon. My sole complaint is the surprise cameo, which pretty much was put to use as a deus ex machina. They were so lucky [REDACTED] decided to put in an appearance.

The second story is a strange and mixed bag of tricks, but not for the reasons you might think, because it's mostly a pretty decent detective story. The problem is that the various components don't "gel" together all that well.

A story best described as the aftermath of the previous case and "the Mystery Train was such a disaster" that "the Sebastian family decided to make up for it" and invited Richard Moore, Rachel and Conan to their villa in Izu – apparently famous for its tennis court. When they arrive, they find a group of college tennis players who use the court to practice and one of them gives Conan a light concussion with a flying tennis racket ("mada mada dane"). Bourbon is also there under the identity he was introduced to the reader. Conan is the only one who knows it. This seriously hampers his investigation when he wakes up in his room with a body blocking the inside the door, which places him smack in the middle of another locked room murder.

I liked the premise of Conan waking up in a locked room with a murder victim and the solution to the locked room found a new and original way to use an age-old trick. Something that has often been used for a very different type of impossible crime, but the premise and locked room-trick should have been two separate stories. I think it's a waste to not have used the premise for a story in which Conan is the only suspect. You can even have a never-before encountered police inspector who learns Conan has been involved in a ton of murder cases and begins to suspect he's a homicidal child. I don't think it helped the murderer stood out like sore thumb or that the plot played second fiddle to Bourbon looking over Conan's shoulder.

The last chapter sets the stage for another Kaitou KID heist, which was alluded to in the opening chapter, but Jirokichi Sebastian had to move the exhibit in the wake of the Mystery Train disaster. But the challenge to the master thief stands. KID already promised to steal the Blushing Mermaid on the opening night of the exhibition. Something that's easier said than done, because the pendant with a red diamond is stuck to the back of a turtle, named Poseidon, who swims in a large, bulletproof aquarium surrounded by twenty guards – which is as good as burglarproof. KID lives up to his reputation and stages a grand magic trick that makes both the turtle and pendant vanish from the aquarium. And leaves behind a note saying "the shy mermaid has dissolved into foam in my hand." This story will continue in the next volume.

So, on a whole, a pretty strong and interesting volume, but with all of its strength and interest lying in the Mystery Train story. The second story was not bad, but uneven and can't judge the Kaitou KID story until I've read vol. 79. A volume containing another promising-sounding, half-a-dozen chapters spanning impossible crime story involving vampire lore. More than enough to look forward to!
