Okay, so there's a few things I need to explain before you read this.

First of all, while it won't be obvious or relevant right now, Shinichi spent his time in middle school traveling with his parents. What I mean is that he was in Japan through elementary school, went traveling for middle school, and returned at the start of high school while his parents continued traveling. This will show up later on, and while it won't be a big point to the story, I figured I get it out of the way now rather than explain it later.

Second, this only loosely follows the first and part of the second manga chapters. After that, it's all original. You'll see quite a few differences as you read. So please don't expect it to be exactly the same.

I had a third point but I can't remember it right now.

It should be obvious by now that I do not own Detective Conan.

OH! Right. And Shinichi will not go by Edogawa Conan in this. Getting it out there now so if it bothers you or you don't like it, then you can back out of reading it right now.

I think that's it for now. The first few chapters are mainly going to be setup and showing how the story is changing.

One more thing. This will probably not go how you expect it to go from reading this. I did not start this story with the intention of rewriting the entirety of Detective Conan. I had one main point in writing this and that will be revealed later on. I highly doubt anyone will guess what that point will be. Some may not like it, but those who don't can stop reading any time they wish.

I think that's it, so I hope you all enjoy this story!

Shinichi fucked up. The second he noticed only one of the men he'd seen earlier should have tipped him off. When he felt that blow to the back of his head, he knew he'd made a mistake. A deadly one. He only hoped that Ran would forgive him for leaving her like that. Damn it! He hadn't even been able to tell her how he felt! He should have let the police know. He should have stayed with Ran – please, please, don't let them go after her for his stupid mistake – should have done anything differently.

Now he was going to die here. Alone.

Shinichi really fucked up. If he somehow survived this, he'd start getting backup before chasing after shady looking men going down dark alleys at night.

What did it say about his life that he had never done so before? Had he really been that egotistical? To think that everything would always work out because it had before? Because by some miracle he hadn't been in this dangerous a situation before?

Almost as though through a fog he heard voices. They were muffled, and he wasn't able to make anything out. It was probably the men he'd followed. He was powerless as fingers roughly grabbed his hair and dragged his head and upper body upright, something being forced down his throat before liquid was poured into his mouth and he reflexively swallowed what was more than likely poison.

His head hit the ground again and he watched the blurry outlines of his attackers moving away. They were leaving him to die. This really was the end.

A searing pain ripped through his body, and Shinichi felt as though he'd been set on fire. He couldn't even scream as the pain became worse. 'Ran,' He thought as his vision dimmed, before finally giving way to the darkness.

Shinichi slowly came to at the sounds of people yelling. Slowly opening his eyes, the blurry shapes gradually cleared to reveal officers in front of him. The first thing he thought was how glad he was to be alive. The second was whether Ran was alright or not. The third was that he should tell these officers what he'd overheard so they could arrest those men.

"Are you alright little boy? Can you stand?" Shinichi blinked in confusion as he sat up. Surely they couldn't be talking to him – he was a teenager, not a little boy. "How did you hurt your head?" Reaching for his head automatically, the pain came back as his hand landed on the spot he'd been hit. Hissing slightly, he pulled back to check for blood and stared at the sleeve that was hanging far over his hand. Glancing down his eyes widened at the sight of the much too long pant legs.

He was in shock as the officer picked him up and told him everything was alright and he didn't need to be scared anymore. Another officer was calling it in, mentioning how they'd found a young boy, between the ages of five and seven – possibly a grade school student. 'G-Grade school?!'

He continued trying to process what was happening as the officer carried him back to their station. He wasn't sure what was happening anymore. He knew he wasn't really tall, being around average height, but even so nobody should mistake him for a grade school student! And that officer had picked him up like it was nothing! Something was wrong, and Shinichi needed to calm down and figure out what.

The pounding in his skull from that hit wasn't helping any. Closing his eyes and taking deep breaths, Shinichi thought back to what had happened. He'd followed the shady man in black and saw him blackmail someone else. He'd been hit from behind with something hard. He was willing to bet it was a pipe or bat. They'd fed him something…poison probably, and his body had felt like it was on fire. Almost like his bones were melting before he'd blacked out.

And then the police had found him and now were calling him a grade school student.

He was missing something. Something important.

Shinichi frowned. He was getting nowhere. Opening his eyes, he waited as patiently as he could while some doctors checked him over and patched his head wound. It still hurt like hell, but at least now he hopefully wouldn't get an infection.

Looking around the station he paused when he got to a mirror. It was at the wrong angle to look at, but maybe something about that supposed poison had done something to his appearance to make the officers believe he was a child. Hadn't they said something about it not being tested on humans yet? Maybe it worked differently on humans?

Shinichi paled slightly. What if they were watching him to make sure it killed him? If he was their first test subject, wouldn't it make sense to stay and make sure he was dead? It made sense, but surely they would have left before the police got there. He doubted they would risk being caught. They could always look at the news to see if there was word of his death. He frowned again, he wasn't dead. The poison hadn't worked, so what would happen once they realized he was still alive? Would they come after him?

They way they'd handled everything had shown it wasn't their first time doing this. At least that was true for the long-haired guy. He'd stayed back to make sure everything went to plan and nobody interrupted. He'd called the shots, probably been the one to give him the poison as well. Was he the one in charge? He'd…he'd said something about an organization. Which meant there were probably more people, but Shinichi had no way of knowing how big it was or how many people were involved. Was it like a gang? Bigger? He'd never even heard rumors of an organization of people wearing black at headquarters. Did that mean they were relatively new?

No, with that much money involved and how practiced that man was, he doubted this was anywhere near his first crime. Which meant it probably wasn't a new organization. That thought left chills going down his spine. If they weren't new, and there weren't even rumors about them, that probably meant there was never anyone left to spread the rumors. Or worse, they had people working for them inside the police to keep information about them buried or destroy it.

Shinichi didn't know what to think. He could be overthinking it. Maybe that hit had done more damage than he'd realized and he was dreaming. Or that poison wasn't really a poison and he was hallucinating. Swallowing thickly, he shook his head and almost jumped when a hand landed on his shoulder.

The officer from earlier was smiling kindly down at him. "It's alright if you don't remember, it must have been really scary." Shinichi hadn't realized they'd been talking to him. "Do you want something to drink?" Nodding, he waited for the officer to leave before slowly sliding off the stool – why was it so tall – and making his way over to the mirror. Hopefully some of his questions would be answered.

Pausing just out of sight, he took a deep breath and stepped in front of the mirror, eyes widening when he saw his reflection. Reaching one trembling hand up, he felt his stomach drop and twist as his reflection did the same.

Staring back at him was Kudo Shinichi, high school detective, but Kudo Shinichi, back as he was when he was in grade school. He was in way over his head. For once, the great high school detective Kudo Shinichi, said to be the next Holmes, who always manages to solve the case and find the truth, didn't know what to do. He needed help. And there was only one detective, one person, he could think of to help him.

He needed to find a phone.

Shinichi panted as he double and triple checked around him. He refused to be caught off guard like he'd been earlier tonight, and those officers hadn't seemed like they'd stop searching until they found him. Only once he was sure the coast was clear did he run for the gates to his manor. It was a risk, coming here, but there was nowhere else to go at the moment. He needed to get into dry clothes before he caught a cold, and calling from the manor's phone would make his story more credible.

Reaching the iron gates, he cursed his tiny child body as he stared up at the lock far above his head. Hefting himself up to the bottom rung, he stretched as far as he could, the lock just out of his reach. Jumping back down, he bit the inside of his cheek, a habit when he was nervous, and thought over his options.

He could go find a payphone, but then he'd be out in the open and the police or those men in black from before could find him. He could continue trying to reach the lock, but if he slipped and fell he could make his head injury worse. He could get someone to open it for him, but it was more likely they wouldn't believe him or would call the police again. Looking around, he froze when an explosion happened nearby. Head swiveling towards the source, he blinked and grinned at his first stroke of luck that night.

Running over to the aging professor he was neighbors with, Shinichi called out to him. "Professor Agasa!"

Standing up, the elder male blinked down at him. "Who are you?"

"It's me! Shinichi!"

"Oh, are you a relative of Shinichi's? You look just like him when he was your age."

"No! Professor, please, you have to believe me! I'm Kudo Shinichi! Second year at Teitan High School!"

"Now, now, Shinichi isn't at home right now. Do you want to go in and wait for him?"

Shinichi bit his tongue to keep himself from arguing that he was Shinichi. Professor Agasa was getting older, and he wouldn't be able to defend himself if those men from earlier went after him. Maybe it would be better if he let the professor believe he was a relative. He could always explain the situation later, and the professor was offering to let him inside. He took a deep breath and nodded slowly. "Yes please."

The shrunken teenager felt himself finally relax when the door to his manor shut behind him. The professor led him to the library and told him to wait there while he went to find something dry for him to wear. Shinichi waited until he was out of sight before climbing onto the desk chair and grabbing the phone.

Dialing the number he'd been forced to memorize, he gripped the phone tightly and prayed that the other person would pick up.

Only when he heard the older voice on the other end did he let out the breath he hadn't realized he'd been holding. "Tou-san? I…I need your help."

So there's the first chapter. Shinichi does the smart thing and calls his parents for help. Don't forget to let me know what you thought!
