Hello there. 'Tis your favorite spazz, Chaos! Here to write a crossover to end all crossovers. Now, this story is for fun. I've been wanting to throw these characters together for a LONG time. And now, I'm going to.

You see, I'm a big Sherlock Holmes fan. I think that contributed to why my favorite Disney movie is The Great Mouse Detective. I'm also a rabid Count Cain fan girl. Seeing as these characters fit together so well, I thought 'Why not throw them all together?'

To do that, I needed a way to fit Basil in, as he is a mouse. So, Kingdom Hearts popped into my mind. And who else but Axel to show these detectives through the different worlds?

And, uh, in my story Holmes and Basil are 'young men'. Because I say so.

There might be time differences, and what not, but Axel has the spiffy ability to jump world from world. So, that's my excuse.

Speaking of which, here's Axel with the disclaimer:

Axel- -sigh- She doesn't own me, Sherlock, Basil, Cain or The Phantom of the Opera, or anything else that pops up in the story.

So, I now present to you a story written for the pure fun it. A story were I can spazz as much as I'd like. A story that will crossover more then just my main characters.

But, above all else, I present to you The Greatest Mystery Ever Solved. (Original, ne?)

There was a knock at the door. I pulled the covers securely over my head. Surely Marry or Riff would get it and turn the visitor away. They knew my sleep habits.

If only Riff were that considerate.

Moments later Riff was at my door, "Master Cain. There are three young men here to see you."

I rolled over and looked at my man servant.

"Master Cain! You're still in bed!"

I sighed and sat up, " Aren't I normally?"

"It's a bad habit." Riff responded, gathering my clothing.

Lazy I got out of my bed, "Yes, well. I can afford a bad habit."

Riff smiled, "Perhaps one or two."

I rolled my eyes. So I wasn't a model citizen. Can you expect me to be?

After getting dressed, I headed down stairs. My visitors had probably been waiting a half hour at least. Not that it mattered. I shouldn't be bothered so early in the morning.

Upon entering the main room, I saw a strange assortment of people. One sat examining everything in the room, and had the slight appearance of a hawk. Sitting next to him was a boy around my own age, with light brown hair, and slightly mousey features. Sitting in the arm chair was another male around my own age. He looked normal, except for his long red hair and strange marks under his eyes.

They all looked at me at the same time. These visitors were quite curious, but I learned the more curious the more dangerous they can be.

The hawk-like one looked at me, "Living all alone, I see. And with no woman in your life."

"Save for a sister." The mousey one added, " And a manservant who takes excellent care of him."

I took a step back. How did they know? Perhaps they were sent from my Father. If he can be called a father.

"Ah. Shocked?" The hawk put on a smile, " From the state of the house, I can tell that you live alone. Only a young person such as yourself would neglect to have the servant keep it in tiptop shape. And, if you did have a woman, you would have been awake by now."

The mouse cut in, " But the young girl who answered must have been your sister. If there is no woman, and you are so young, she's hardly likely to be a daughter.

From the state of your clothing, I can deduce that a servant must be watching out for you. And the most likely candidate was the manservant who went to fetch you."

Ah. So it was simple deduction tricks. I had a bit of the power myself, but I didn't like to show off the way they did. I saw the red headed one smirk.

I sat, "And I can see you've traveled a long way."

The hawk smirked, "I see you've a taste for deduction as well."

The red headed one spoke at this point, " It's a good thing you do."

I looked at him. Why would that matter?

"You see. I'm looking for detectives. Only the best will do. And you three seem the best ones for the job.

Allow me to introduce us. This is Sherlock Holmes."

He indicated the hawk-like ones.

"And this is Basil."

He motioned to the mousey one, who was currently playing with his hair, as if it were completely new to him.

"And my name is Axel."

"Charmed to make your acquainted. As I'm sure you already know, I'm Cain C. Hargreves. Now. Why is it you need detectives?"

"I have a mystery that completely vexes me."

"It requires three detectives?"

"Possibly."

"Possibly?"

"Yes. I thought the more, the better. Now. Before I give the actually case, I'd like to give you some trial cases. I know of three cases that your help will be of the greatest assistance. I would like you to solve them all, together."

"Not interested. I'm not a detective anyway."

I was about to leave when he spoke again.

"You'll meet plenty of women."

He had caught my interest.

"These two have all ready agreed."

It was just the sort of thing I needed. Riff knew how terribly bored I was. A chance to get out. The idea excited me. I turned back to face him. I noted how he could hardly be from England. I could tell from his posture, and his accent. Also, the red hair made it all the more obvious.

"Allow me to inform Riff I will be leaving for an indefinite period of time."

With that, I got up and prepared to leave.

Not long after we began our travels. It turned out Sherlock seemed to know a lot about the criminal world. Basil and I listened with rapt attention. Axel seemed to be bored by the whole thing. After I while I released I had no idea where I was being taken to. I decided to ask.

"We're headed to France."

I was taken aback, "Why so far away?"

"Because. That's where our first mystery lies."

"Why don't you fill us in on the mystery now?" Basil asked.

"There's an Opera house in France. Rumors have been floating around that there's a ghost. Normally, no one would care to investigate. Recently, though, a man named Joseph Buquet has died. Now, the police have deemed it a case of suicide, but plenty of people aren't satisfied with that excuse. So that's where you come in."

"A murder?" Asked Sherlock.

"And a rumor." Axel replied.

I allowed my self a smile. This promised to be an interesting case. And in France!

Axel looked out the window, " You know, the people at the opera have already decided who committed the murder."

"Who?"

"The Phantom of The Opera."

So, I end it there. With the detectives headed to the Opera to investigate a very well known mystery. One of my favorites too.

Told you we were crossing over.

Also, I think I write next chapter from Sherlock's POV.
