Holmes' Revelation

Conan and his caretakers, Ran Mori and Kogoro Mori, are given a free trip to London after finding a cat that belongs to Diana Kingstone, a rich British woman. For the trip, Conan is given two pills by Ai Haibara; the pills will temporarily suppress the poison which turned him into a child allowing him to use his teenage identity, Shinichi Kudo, to bypass airport security. After the medicine wears off, Conan rendezvous with Ran and Kogoro to visit the Sherlock Holmes Museum at 221B Baker Street. There, Ran phones Shinichi (Conan using his voice-changing bowtie) and is upset about his apathy. Shortly after, Conan overhears a child named Apollo Glass who is searching for Holmes. Posing as Holmes' apprentice, Conan befriends Apollo who reveals a man has given him a list of riddles which needs to be solved in return for sparing someone's life. Meanwhile, Ran is walking by the Statue of Sherlock Holmes where she meets Minerva Glass, a professional tennis player and Apollo's elder sister; Minerva tells Ran to give up on love relating it to the tennis mantra "Love is Zero". Ran decides to call Shinichi; during the conversation, the latter accidentally reveals he is by Big Ben. Ran corners Conan forcing him to take the medicine for the return trip to protect his identity. Believing that Shinichi was hiding from her, Ran is hurt and repeats Minerva's words. In return Shinichi confesses his love for her and rebukes Minerva's statement by exclaiming that everything starts from zero.

The next day, the man distributing the riddles in London is identified as Sabara Hades, an international serial bomber. Conan begins decoding the riddles in order: "A rolling bell rises me" refers to Big Ben; "My portion is like a chilled boiled egg like a corpse," leads them to City Hall where dolls engraved with Mazarin Stone are found. Referring to The Adventure of the Mazarin Stone, the group beheads the doll where they discover the letter T; "I finished up with a whole pickle," leads them to 30 St Mary Axe where they find scratched up pens labeled as Dancing Men. As in The Adventure of the Dancing Men, matching the top and bottom caps to reveal the letter N; "It rings again for my hatred" leads them to cross the Westminster Bridge towards Big Ben. On the bridge, they find a drain engraved with Valley of Fear. Referring to The Valley of Fear, they find a drain cover with the letter A in the river; "Now I remember to ask a cake to celebrate in advance" leads them to St Bride's Church where they find envelopes entitled A Scandal in Bohemia. Soaking the envelope in water reveals the letter S; "I'm a long nosed wizard in a castle" leads them to Elephant & Castle tube station where they find a man carrying a suitcase with the word identity on it. Referring to A Case of Identity, they find the letter U on the inside of the man's pants; "It tells me to finish everything piercing a white back with two swords" refers to the logo of a local porcelain store which displays an ornament with strings and bells attached on the end. Referring to A Study in Scarlet, they locate a red string with the letter R. Rearranging the letters results in Saturn, a reference to Saturday. Connecting the riddle's locations on a map forms a tennis racquet referencing the Wimbledon championships.

Conan enters the All England Lawn Tennis and Croquet Club during the Wimbledon finals. Minerva has been serving "help" in braille into the court. Conan calls out to her revealing he understood her message. In response, Minerva serves more messages revealing Hades intends to kill her mother with a bomb when the match ends. Conan deduces Hades is directly opposite of Minerva's mother, as he intends to record her death, and is able to locate him. Conan coincidentally finds his parents, Yusaku Kudo and Yukiko Kudo, who assists him in apprehending Hades; Conan is then given another pill, by his parents, to bypass airport security to return home. With Hades incarcerated, Minerva is able to focus and win her match. As Conan and friends prepare to return home, Ran converses with Minerva and repeats Shinichi's words. Minerva, having made up with her lover, acknowledges that everything starts from love.

Characters designed by Gosho Aoyama in this arc. From left to right is Juno Glass, Ares Ashley, Apollo Glass, and Minerva Glass. Minerva's character was based on Steffi Graf.

In 2003, the creator of the Case Closed series, Gosho Aoyama, had stated he would draw a story arc taking place in London.[10] To this end, he traveled to London and visited the sites that would appear in the story arc; for sites he had not visited, he used Google Maps. During his trip, Aoyama took special note of a phone booth near Big Ben and a drain pipe, engraved with the words "Valley of Fear", on the Westminster Bridge; these two aspects were used in the story. While creating the story, Aoyama expressed difficulty incorporating English in the text. He also revealed Minerva Glass, a fictional tennis player in the story, was based on professional tennis player Steffi Graf and the scene where Conan calls out to Minerva during her tennis match was inspired by an event during the 1996 Wimbledon Championships where a fan jokingly shouted his proposal to Graf during her semi-finals match. For Shinichi's confession to Ran, Aoyama created the scene with Sherlock Holmes' poor ability with relationships and the phrase Yakkai na Nanjiken (厄介な難事件, lit. "A troublesome and difficult case") in mind.[10]
