The Case

While Kogoro and the group are watching a news report on a recent bank robbery, Amuro stops by with sandwiches from the Poirot after finishing his part time job for the day. After commenting on the robbery, Amuro reveals that he wants the scoop on Kogoro's newest case request after deducing from Kogoro's appearance and habits that Kogoro had a case. Kogoro gets a text from the client requesting that Kogoro switch the meeting location to the Café Columbo, and Amuro goes with them after changing out of his work clothes.

At the Columbo, Kogoro explains to Amuro the request was to find the locker a key belongs to. The client fails to show, so Amuro, Kogoro, Conan, and Ran go back to the Mouri Detective Agency to make sure the client didn't actually turn up there instead. When Amuro arrives at the agency, he and Conan notice someone had broken in and appeared to have intercepted the client while they were out. Stepping outside, Amuro explains his deductions to the rest of the gang and that the culprit is hiding in the restroom. Before Amuro can open the bathroom door, a gunshot rings out, and Conan rushes in to find a dead man who apparently committed suicide with a gun and a taped-up crying woman.

Suicide?
	Location: Mouri Detective Agency Victim: Man Cause of death: Gunshot wound When Conan and the group went inside, they found Kashituka who's been taped-up. Also they found the dead man holding the gun. It seems he committed suicide.

Kidnapping

The group escort Kei Kashitsuka back to her condo. Kei goes tidy her room but secretly leaves the condo with Conan following her. As Kogoro, Ran and Amuro waiting for Kei they start searching for listening devices as when Sera called Ran the former's voice wasn't clear.

Murder
	Location: Condo Victim: Man Cause of death: Beaten to death Suspects: Kei Kashitsuka Locating the final listening device in a suitcase under the bed, Kogoro, Ran and Amuro open it to find a man beaten to death inside it!

Later they receive an email from Kei Kashitsuka and order them not to attempt to find her or she won't guarantee Conan's safety.

Kidnapping
	Victim: Conan Edogawa Suspects: Kei Kashitsuka Kashitsuka drugged Conan with a fruit juice then sent warning email to Kogoro that she will release him at dawn, unless they attempt to find her.

Ran contacted Agasa for help while Kogoro and Amuro discovered more information.

Resolution

  Show spoilers »

From the evidence that Conan gathered during time at the gas station, he concluded that Kei Kashitsuka's real name is Serina Urakawa, a bank employee where the recent robbery took place. Serina isn't Kenya Shouno's younger sister but is his lover. The name Kei Kashitsuka actually belong to the man that Serina murdered at Mouri Detective Agency, using shoe rope trick to pull the trigger. Her motive is to kill the three robbers that was resposible for Kenya's death and so she tracked down his friend named Kei Kashitsuka. However she stumble across one of Kei's friend(one of the robber) and in self-defense, killed him. After planted several listening devices, Serina heard that Kei will request Kogoro to search for the rest of money's location and so she ambushed him at the agency. She used stun-gun on him, switched their belonging and used the trick described above to make it seem that she's a victim.

Conan then further his deduction by said that he know that Serina will committ suicide after she murdered the third robber. Serina then accept his condition and so he tell her that the third robber's true identity is Takayo Tegawa. From the footage and information from Serina, Conan concluded that the third robber's true identity is Takayo Tegawa as both Toyokita and Furiya are right-handed (Tegawa is the only left-handed person). Tegawa's suspicous actions are also serve as an evidence, she bought beef-bowl rice to change the 10,000 yen bills number and she switched off her phone to prevent the police to find her. After the deduction Serina agreed to turn herself in but she said that one thing is wrong, she only took 2 guns from Kei Kashitsuka's hideout, alerting Conan that the third one must still in Tegawa's possesion!

Tegawa then burst into the car and take Conan as hostage to force Serina to drive to place where there no people so she can silence them without fear!
