Case

Situation

Detective Boys and Ami Komachi.

Conan and the Detective Boys are having a leisure time at Yujiro Tamaki's bookstore café, when a woman named Ami Komachi enters the bookstore. As part of a recent purchase of used books by the bookstore, a novel named "The Lonely Sea", one of Ami Komachi's father's keepsakes, was accidentally sold to the bookstore. Ami asks if she could buy the book back, but unfortunately, the book was already sold to another customer.

Shortly after, that customer, a regular customer named Kenichi Kirishima, enters the bookstore. When the Detective Boys ask whether he has a book named "The Lonely Sea", Kenichi says he remembers buying it from the bargain items rack in the bookstore, and that he already sold it to yet another customer. He quickly pulls up an online listing on his phone showing the sold-out item.

After Ami, who gives up on finding the novel, and Kenichi leave the bookstore, Haibara tells the Detective Boys that she noticed that the listing for the novel was for 200,000 yen, even though the books from the bargain items rack should not be anymore than 500 yen. Yujiro Tamaki confirms the low value of the book by saying that the novel was only recently published, and it is not that rare to find.

A few hours pass, and the Detective Boys decide to go home, but Yujiro says that he will join them on the way home to drop off Kenichi's lost key. When Yujiro opens the apartment door, he and the Detective Boys find Kenichi lying dead.

Murder
	Location: Kirishima's apartment, Beika Town Victim: Kenichi Kirishima Age: 32 years old Time: Between 16:30 and 17:30 Cause of death: Cerebral contusion Suspects: Ami Komachi

The police arrive, and Conan points out that the blood marks on the table are in an L-shape, indicating that an object of that shape was placed there before the murder, and taken away afterward. The police also find a safe in Kenichi's apartment. The key that Yujiro was going to drop off is the key for the safe, and after unlocking the safe, lots of jewelry is found. Takagi mentions that the jewelry is similar to that of which was recently robbed from a jewelry store. It is confirmed that Kenichi was a part of that robbery.

Robbery (Past)
	Location: Unknown Jewelry Store Culprit: Kenichi Kirishima

The book cipher.

Conan deduces that the reason the price of "The Lonely Sea" novel was so high was that Kenichi was involved in black market deals, specifically in the exchange of robbed goods. The book is used as a camouflage for the exchange. Meanwhile, the police use the apartment's security camera footage to narrow down the suspects who murdered Kenichi to two people: Ami Komachi and a delivery man.

Conan wonders why the murderer had to take a book from Kenichi's apartment, and then finds a notebook with a ripped page and some blood. After shining his Wristwatch Flashlight onto the page underneath at an angle, a page filled with numbers is revealed. Conan notes that each row of numbers has three numbers. One column of numbers keeps going up with each consecutive row, the other two columns have seemingly random fluctuations in numbers. Conan realizes what the numbers mean, but instead tells Yujiro that he should know what the numbers mean. Yujiro says that they are a book cipher, each row of numbers contains the page number, paragraph number, and line number. However, the numbers cannot be deciphered without the book.

Using the set of receipts that Kenichi stored away, the Detective Boys narrow the list of books down to those that are on the receipts, but not in Kenichi's apartment. This leaves 20, and Yujiro narrows it down further by using the average page length in each book. With three books left, and the bookstore having a copy for each of them, the Detective Boys, Yujiro, and the police head to the bookstore to decode the cipher.

Deliveryman's reminiscence.

Conan decodes the cipher, and the next day, at an inconspicuous corner in Beika City, a suspicious man arrives at a set of coin lockers. As soon as he opens one of the lockers, Takagi, Megure, and Chiba surround him. The man tries to escape, but Takagi pins him down and arrests him for interfering with the police. The Detective Boys recognize the man's face as the delivery man found in the security camera footage.

The man claims that he didn't intend to kill Kenichi. One day, while he was delivering one of Kenichi's purchases, he saw a box which contained the secret to how Kenichi was carrying out black market deals. Out of greed, he intercepted them, until he was found out by Kenichi. In the scuffle that followed, he accidentally shoved Kenichi into the table as self-defense, but ended up killing him.

Conan says that by using the book cipher and the locker, members of the black market deals avoided direct exchange, and therefore it is harder for the police to discover these illegal exchanges.

Ami, whose father's keepsake novel was hidden in the locker, was able to get the novel back. She regrets having gone to Kenichi's apartment, which caused her to become a suspect. Meanwhile, Genta, while playing soccer with the rest of the Detective Boys, accidentally drops a bunched-up piece of paper from his pocket. Upon having Mitsuhiko open the paper, he finds that it contained a book cipher. Genta was using it to hide the location of snacks from his mother, but he forgot what book he used for the cipher. He tells everyone to help him search for the book, but Conan doubts it, saying in his thoughts that Genta will never be seeing those hidden snacks again.
