It was a good thing Yoru decided not to rest. It wasn't a good thing for a person's help after they are known to be sick and don't try to be well rested to get better, but for a hard working detective and child prodigy like Yoru avoiding rest was giving his enemies a reason to fear him.

"Mama, hurry! Hurry!" A little boy urged his mother as he ran.

"Hiro, don't run like that! It's dangerous!" The little boy's mother chided following her son not too far from behind.

"It's fine. It's fine. Uwwaaahhhh!" Not noticing a box nearby, the little boy named Hiro accidentally tripped over the box and was about to hit the floor. That is until his mother grabs his arm just in time.

"See. I told you not to run. It's dangerous."

"Sorry, Mama."

At that moment, it came to Conan and Yoru. The trick behind the victim's death and the mystery behind the victim's strange hand shaped bruise on his ankle they finally figured it out. Now all that's left was to set up the stage and unveil the truth behind this sorrowful tale.

A smirk slowly forms on the two's face upon their finding.

"You wouldn't by chance happen to be thinking of the same thing as me...?" Yoru asks Conan.

"Yeah, and I happen to know who did it too."

"What a coincidence. Me too."

*cough* *cough* *cough*

But before he could do anymore, Yoru soon breaks out in a coughing fit and collapses on the ground.

Eventually, he was taken to his room by his father when the staff had informed his father of his condition. Conan was concerned about Yoru's health but knew that he had more important matters to attend to.

Conan wasn't going to try explaining how he solved the case this time because he couldn't take all the credit. Using a simple piece of technology that sticks in the ear so a person can hear what the other has to say Conan contemplated letting Rin's father get all the credit. He was carrying the technology, but he didn't think he needed to let anyone else have it.

' There's no time to think about this,' Conan told himself. ' I just need to remind myself I can think ahead of a murderer...can I afford to help anyone this time?'

Yoru felt like their was a dog sleeping on his foot. Being sick made his father sleeping with a book stretched out on Yoru's foot feel like a big animal.

In another room, Conan had already set up everything he needed for the deduction. He put Kogoro to sleep, his bow tie was set to Kogoro's voice, and he kept himself hidden while everyone's eyes were on the sleeping detective. Now all that's left was to wait for Inspector Megure to bring the suspects in.

"Mouri-kun, what did you call us for this time... Oh! It can't be!" Inspector Megure exclaimed in surprise upon laying his eyes on the sleeping figure on the chair.

"It's here!" Takagi added.

"It can't be... the Sleeping Kogoro!"

"That famous detective!"

Nicholas and Ruri both expressed their surprise to see that the annoying detective was actually the famous detective, the Sleeping Kogoro.

"Looks like all the actors are in place. So let us begin this tragic screen play." Conan spoke in Kogoro's voice through the voice changing bow tie.

"So you know who did it? So it was murder after all!" Megure said.

"Now, now, Inspector. Let's take things slowly right now. Surely, we'll all the answer to that once this is all done. First, I received some very crucial information from Conan who received a testimony from our guest detective's son."

All eyes lock on Yoru's father.

"According to his son, he had a little run in with Ms. Miller while he was retrieving some cold medicine. And late last night, he went out to get a glass of cold water but felt someone staring at him when he came back to his room."

"Hold it! You can't say it was Rose just because of that! So Rose bumped into a kid that doesn't mean she was the one following the kid!"

"Even if she did, it doesn't even have anything to do with this case!"

Both Nicholas and Russel rebuked in defense of their friend.

"I wouldn't say that it doesn't have anything to do with this case. Upon hearing the kid's testimony, I had forensics do an inspection on Yoru's medicine."

"As per Mouri-san's instructions, we did a check up on the pills and found multiple fingerprints on one pill in particular that didn't belong to the child, Yoru. The late victim, Mr. Daichi Takano, and Ms. Rose Miller's"

Yoru could see further ahead to see a policeman carrying a bag of pills walking towards him. It didn't take lots of brain power for Yoru to deduce this officer was giving him his pills. Sure enough, when the police officer made it to Yoru he held the bag out to him.

" Your father says he couldn't find your pills so he asked me to look for them. I believe these pills belong to you."

" Oh. Are you sure they don't belong to someone else?"

"Now then Ms. Miller, can you please explain how a pill with both the victim's and your fingerprints got on it?" Conan questioned but only got a silent reply. "And with further investigation, it was found that this particular pill was much different from the rest of the medicine. Or rather that it was made differently not something that you'd find in a regular pharmacy."

"Wait? So you're saying that Rose killed Takano for that?" Nicholas interjected. "That's ridiculous! There's no way she'd do something that inhumane!"

"That's right! Rose isn't the type of person to do that! In the first place, she and Takano weren't even in the same division so that pill would be meaningless to her!" Russel added.

"But I never said that she was the one who killed to get this pill as there was yet another set of fingerprints found." Conan enlightened the two IT workers.

"Another?" Ruri repeated.

"That's right. One that didn't belong to anyone in this room."

"But what does that have to do with anything?" Nicholas asked.

"Because it belonged to someone that you people knew very well and the reason why you're here."

"Wait, you don't mean..." A cold sweat drops down from Nicholas cheek as Russel and Ruri both turned pale.

"That's right. It belonged to your late colleague, Mr. Todd Fianschel."

Now this caught Inspector Megure's attention as well as Detective Takagi and Detective Satou's attention. For they had also known about the death regarding the late Todd Fianschel. "Mouri-kun, you don't mean!"

"That's right, Inspector. That pill was originally developed and made by none other than the late Todd Fianschel who was murdered by Mr. Daichi Takano."

The two friends point of view and respect didn't change because all the facts showed she was fighting for her life. The only thing they didn't count on was Rose standing up, rubbing her forehead, and about to tell Conan the confession he wanted to hear.

"That's right. It was me. I killed Takano-san." Rose admitted with her head head hung down and her eyes hidden under her bangs. "I couldn't allow Todd's work to fall into that man's hands. Not after what he did to Todd just to steal Todd's hard work."

"Rose..." Ruri and the rest of their friends couldn't believe what they were hearing. It was as if time had froze when all life drained from their faces.

"I can't hide it anymore. You can take me away." Rose held up her both of her hands together ready to be cuffed.

"Takagi..." One word from his overweight superior was enough for Takagi.

Just as Takagi was about to handcuff Rose, Conan had cut in.

"Wait, Detective Takagi. Are you sure you want to hastily handcuff her like that?"

"But Mouri-san, didn't she just confess to killing the victim, Takano-san?"

"Yes, she did. But that's only from her perspective."

"What do you mean, Mouri-kun?" Inspector Megure inquired.

"Do you remember the condition of the victim's body when he was found and the location he was found?"

"Yes, when we found it in the river, we found countless of bruises and injuries on the body mostly likely from the culprit who held a grudge against the victim. And from Ms. Rose's confession, there shouldn't be any better motive than her's. Is there something wrong with that?"

"Very. Because of one important detail that we overlooked, we made an incorrect assumption."

"What do you mean?" Megure asked.

"Ah!" Detective Satou exclaimed in realization. "The river! The corpse was most likely swept away by the river's current and was found by chance at that location which we assumed was the murder location."

"That's right. The place that we assumed where the victim died was incorrect."

"Then where did the real murder scene?"

"Inspector, did you know that if you walk upstream the river, you'll find a high waterfall with a steep incline?"

"You don't mean!"

"That's right. It was at the top of the waterfall where the cliff was that the victim fell to his doom."

"I see that would explain the numerous bruises and injuries over his body. Most likely from when he fell."

" There's no gentle way of putting that dying from a fall like that could only have made the bruise with sharp point sticking into his arm. It could have felt like thirty six spears ripping inside the muscles...if he was conscious when he died the pain would have felt cold and bleeding."

"Rose, you pushed Takano?" Nicholas shakily said in disbelief.

Rose's silent response had only worsened Nicholas's unease.

Russel and Rose too couldn't believe it in their heart that their kindhearted friend could do such a thing like murder even if it was for their friend. But in their hearts, they knew that they couldn't blame their friend for her actions as they too would have most likely done the same thing if they knew about Todd's death.

"I think you people are getting the wrong idea. Remember what I said before. It's still too soon to assume that Ms. Rose is a killer. In addition to the numerous of injuries over the victim's body, there was one particular injury that stuck out the most." Conan interjected.

"The hand-shaped bruise on the victim's left ankle!" Takagi exclaimed.

"That's right. Don't you find it odd how a man who had fallen down a cliff such a bruise. No matter how you see it, it would be impossible for a man to get such a bruise if he had been pushed."

"Mouri-kun, what are you getting at?" Megure inquired.

"Inspector, if you were walking by a river with Detective Takagi and accidentally slipped on a wet rock, what would you unintentionally do in that situation?"

"I'd probably try to grab onto something so that I wouldn't end up falling on the ground like a... natural reaction. It can't be, Mouri-kun!" Inspector Megure finally understood where Mouri or rather Conan was getting at.

"That's right. The one who was actually pushed wasn't the victim but rather the suspect." At Conan's statement, the entire room went silent. The person whom they thought was the perpetrator was actually the victim. And the person whom they thought was the victim was actually the culprit. "And on instinct, the first thing, Ms. Rose did was to grab onto something so that she wouldn't fall to her death and unintentionally the first thing she happened to grab onto was Mr. Takano."

"That would explain the bruise on the diseased's leg!" Detective Satou added.

"How come she's fine if she fell along with the diseased?" Detective Takagi asked.

"Simple, if you checked the scene of the diseased's death, you'd notice a tree growing on the side of the cliff. One sturdy enough to hold the weight of a human body."

"I see so the diseased called out to Ms. Rose and tried to kill her at the waterfall by making it seem like an accident to silence her about their late colleague's death and his crime. Luckily, Ms. Rose was fortunate enough to land on a tree while the diseased wasn't so fortunate." Inspector Megure explained.

"No, you're wrong. It was me who called him out there." Rose admitted. "I wanted him to turn himself in, but..."

Rose didn't need to finish her sentence to let them know what she was going to say.

" He rather kill you than let the whole world know he's a murderer, acted you first where you surprisingly had enough self defense to keep him away, and then you both fell. This wasn't a case of murder or an accident...it all has to do with self defense."

Once the situation was brought to light, Rose was escorted to a police car to have her statement of both Todd and Takano's cases recorded.

Conan breathed a sigh of relief. At last, it was finally over.

"What are you doing?" Detective Satou yelled at Takagi.

"I'm so sorry. It was an accident. I didn't think we'd need it!"

"It's important evidence! How could we not!"

"What's going on?" Conan curiously asked wondering what Detective Satou was scolding Detective Takagi for.

"Ah, Conan-kun." Detective Satou said taking notice of Conan's presence. "You wouldn't believe what this guy did. He just carelessly gave that private detective the pill the deceased Todd Fianschel created by mistake when he asked for the cold medicine we took for forensics. His son's condition was getting worse so he needed the medicine took for analysis, but instead, this clumsy detective ended up giving him the wrong medicine."

Detective Satou accusingly glanced at Detective Takagi.

"I said I was sorry! But we've already got Ms. Rose's testimony so it should be fine." Detective Takagi defended.

"Even so, it's completely unprofessional of you to make such a careless mistake like that." Detective Satou childishly rebuked.

"Couldn't you just ask for the pill back?" Conan asked.

"We would if we could, but that private detective already gave it to his son so we can't exactly get it back." Detective Satou said.

Curious about Yoru's condition, Conan went ahead to check on the boy to see how he was fairing. The last time they met, he didn't look so good so Conan was slightly worried about him.

Getting to Yoru's room was a frenzy. Conan imagined a war zone with lots of bloodshed and feathers blowing through the wind. Conan had the misfortune to talk to Yoru when an American carrying a Thanksgiving basket carrying things Conan knew but never understood and a quilt from South Africa. These people tend to get on other people's nerves but Conan was small so he could squeeze through him.

With no more distractions, Conan found an empty hallway leading to Yoru's room. He wondered if the kid was alright. There was so much he had to ask him like who he was. It was obvious that he was no ordinary kid like Conan. And if he was like Conan, then there was much he needed to discuss with him.

"Hey kid, it's dangerous running around the hallways like that." A voice from behind reprimanded Conan.

"Ah, sorry." It was pointless revealing his intentions to this stranger so Conan just decided to make up some excuse to get this guy off his back. "I needed to use the re—"

As soon as Conan turned around, he saw a very familiar face one that belonged to Yoru except the person in front of him was way taller than the Yoru he knew and much older most likely around high school age.

"You..."

"As expected of you, you can already tell. Yeah, it's me, Yoru Kurihara, a high school student turned into a kid like you. Although not anymore now."

Taking their conversation to a more private location, Conan learned of Yoru's past and his connection with the organization as well the unfortunate situation that lead to his predicament. As it turned out, that pill constructed by the late Todd Fianschel was the antidote to the poisonous drug APTX 4869 that reverted Yoru back to his normal form once he took it.

"I see." Tch, just when he thought he got a lead. It didn't do him much good. It was lucky that he found some lead to the antidote to his return him back to his normal body, but the information for the pill's composition was privately created by a research who is now dead so there was close to little to no information on attaining the cure. "So what are you going to do now?"

"I don't know about you, but I'm going back to my high school life. And I can't exactly let a dangerous organization like that run around now, can I?"

'This guy...'

"If you need anything, I'll be more than glad to help."

"Yeah, me too."
