"How does it feel, setting foot in a house you haven't been in for a long time, Kudo Shinichi?"

Hearing her ask this, Conan is shocked. Immediately, he asks "What do you mean, "Kudo Shinichi"? My name is Conan!"

Kir shakes her head. "No." she says. "Ever since you told me your deduction back at Haido Central Hospital, I realized something about you was different than other children your age. Ever since, I've been thinking about this. But then came the news of you attending Teitan High and the boss assigning me and Vermouth to look into your background. There was nothing about you to be found from before you were 7 years old. It's as if you appeared out of thin air. By mere chance, I noticed one of the files in the "Deceased" section, with the name "Kudo Shinichi" sticking out of the rest. I took a peek and noticed he disappeared the same day you appeared. Even though, that day, Gin and Vodka gave you APTX4869, the date of your "death" was over a year later."

After hearing her explanations, Conan gives up. "I guess you did see through me, after all. You're right. I am Kudo Shinichi. I don't know why, but the APTX4869 Gin forced me to take shrunk me instead of killing me. The reason Shinichi "died" a year later is because a crucial ingredient of the antidote was made illegal in Japan."

"Antidote?" Kir asks. "I didn't think such a thing was even possible. How did you get such a thing?"

"Before I tell you," Conan says. "I want to ask one thing. Did you check if you had any bugs on you?"

Kir scoffs. "What kind of NOC do you take me for? It may have been a long time since my father died in the line of duty due to my own mistake, but I learned to check for bugs every time I make my own moves."

"Very well then." Conan says before explaining about how Sherry shrunk, was given the alias Haibara Ai and how she lives with Agasa, the one living next to Shinichi's house.

"I see." Kir replies. "I suppose, in that case, it's a good thing nobody other than me knows about the shrinking effect of APTX4869."

To her surprise, Conan shakes his head. "I'm afraid you're not the only one. Vermouth knows as well, but for some reason, she hasn't told anyone."

"Come to think of it," Kir said. "She didn't seem all that surprised when we learned from your file that nothing was mentioned from before you were seven years old."

Conan asks in surprise "What do you mean, "learned from my file"?"

Kir is silent for a moment, before she realizes what she just said. "Oops, I guess my past assignment slipped out. I was going to inform you sooner or later, anyway. Several weeks ago, when the article revealing your genius was published, that person ordered me, Gin, Vodka, Vermouth, Chianti and Korn to gather and look into you. Me and Vermouth were assigned to investigate your background while Chianti and Korn were assigned to surveillance. However, earlier, my assignment changed with Chianti and Korn's betrayal. Now, I'm to work separately from the others, looking for them."

"I know what happened." Conan said. "I managed to become aware of their surveillance and had the FBI arrest them in secret, while I sent the boss a message from their phones, in which they claim to abandon the Organization."

"So you know the boss' mail address?" Kir asks. "You sure are full of surprises, Kudo-kun. At any rate, I need to get back to my assigned task. When I can, I will contact the FBI. As for your secret, it's safe with me."

Several days later, Conan and Ran go home, only to notice that Kogoro has a client. What they hear, however, surprises both of them.

"No, no, no!" the lady says. "I don't want any help from an amateur like you! I want that boy genius Conan to help me!"

Kogoro interrupts her rant. "But, lady, don't you know who I am? The great detective, Mouri Kogoro! Whatever troubles you, I can handle it!"

The lady scoffs. "Great detective, my foot! Everyone knows there is NO such thing as a great detective who ends up being outsmarted by a 7-year-old!" she says before noticing Conan and Ran at the door. Suddenly, she calms down. "Oh, hello, Conan-kun. Sorry for my outburst. My name is Shimizu Hana (干水 二亡). I had some trouble at my estate recently. I thought I'd ask Mouri-san for help, but then the article on his failure came out." she said as Kogoro glares at her.

"Did you say your name is Shimizu Hana?" Ran asks. "I've heard of you. You've been appearing in front pages of movie star magazines for the past 10 years or so, right?"

"That's right, dear! I'm quite well-known for my genuine talent, unlike your father over there. Anyway, the thing is, I received this threat letter."

She shows Conan the letter, which says:

"Your 30th birthday is coming up. It has been over 10 years since you took away everything from me. The punishment for your sins has been long overdue. Getting help from outside will not save you, for I have been right behind you for the past several years. No crime goes unpunished."

She explains "I received this two weeks ago. Between then and now, I've been doing all I can to find the one who sent it. The only problem is that the contents of the letter alone are too little to go on. Could you please investigate this?"

Conan nods. Minutes later, he and Ran are riding in a limousine.

"Do you like it in here?" Shimizu asks. "It's the best I could find. And it's a foreign brand. That's what success gets you."

Just when Conan and Ran get out of the limousine, they walk towards the mansion. Conan looks behind him, noticing that the lady seems to be whispering something to the chauffeur, before she runs over.

"Sorry about that. It was something personal I had to arrange with him. Anyway, let's go inside."

As Shimizu, Conan and Ran go inside, the notice right away that several people are waiting inside.

"Let me introduce you to everyone who works here. This is my butler, Nishimura Kazuhiro (西群 一博). Next to him are my maids, Fujita Satomi (藤田 五臣) and Ueda Chiyo (上田 育四). There is also the chef, Nakano Kuro (中之 六郎) and the chauffeur, Matsumoto Minoru (松本 三駕)." she says before looking at her watch. "Oh! I need to do my nails! I'll see you later." she says before heading off.

Right after that, Conan asks one of the maids "Does she do that often?" to which the maid answers. "Yes. Always on the first Friday of each month, at the same time, to the minute. She is quite punctual, as far as that is concerned."

"Does she have any other habits?" Conan asks. The maid says "There is only one other habit like that. She takes a shower twice a week. Always on Monday and Friday and always while dinner is being made."

That night, Shimizu, Conan and Ran are waiting for dinner to be made. As they wait, Shimizu goes to the shower. Just then, the chauffeur leaves, saying he needs to check the car. At the same time, the butler goes to the basement to get some drinks for Conan and Ran, while both maids head to their rooms. 15 minutes later, the chef walks in, telling everyone dinner is ready. Everyone except Shimizu sits at the table to eat. 5 minutes later, the chef becomes curious, as Shimizu still hasn't come back. He goes to the shower room to check. He's horrified by what he sees and screams. Right away, Conan runs over and finds Shimizu with her throat slit. He checks, only to learn she has no pulse.

Looks like Conan has a new murder case to solve. As for the weapon, I have already given a clue as to what it was. Good luck figuring it out.
