AN: Hello. I noticed there isn't much fanfics of "Great Mouse Detective " with Phantom of the opera case, so I made my version. In there will be my OC Elizabeth, Basil's as he is.

Just so you know "Great Mouse Detective" is my favorite Disney movie. It has been part of my childhood as long as I remember.

Enjoy!

It's been almost a year since the Queen's Jubilee and the great fight in Big Ben. Basil of Baker Street, the great mouse detective, and his associate, doctor David Q Dawson have solved many crimes so far. Elizabeth, Basil's niece has been on those as well. Including one, which revealed that Professor Ratigan had survived the fall from Big Ben. That sure was a shocking discovery, but that didn't stop them. Sadly however after stopping Professor many times so far he was still out there somewhere. Basil was ready to go after him as soon as he figured out his next scheme. But this case was something he never expected to affect him.

It all started when Basil and Dawson were sitting in their chairs reading the newspaper and drinking tea. Elizabeth was playing her violin. In the doctor's opinion, Elizabeth played much more lovely than her uncle. Don't get it wrong Basil sure plays well, but it really depended a lot on his mood on what he would play. Elizabeth however, was more like she was making her own. Mostly they sounded good, but there have been a few times it resembles her uncle Basil's way of playing.

"That's new of her." Dawson points out as they hear her playing.

"Yes." Basil said while reading the newspaper. "What a lovely little melody."

Suddenly someone was knocking on the door. Mrs. Judson went to open it and there was a mouse in a suit and satchel. He was obviously in his thirties, clean tanned fur with a little mustache.

"Good day, madam. Is Basil of Baker Street here?" he asked kindly.

"He is." said to allow him in. "You have a guest, mister Basil."

Basil gets up to greet him. "Welcome, sir. I assume you either came here because you need my help or that you heard my niece playing."

"Why would he be interested in Elizabeth's playing?" Dawson asked.

"Isn't obvious, doctor. This gentleman here is a play writer." Basil answered.

"How do you know I'm a play writer?" The guest asked. "I'm not quite famous yet. I have only written two plays so far."

"There's a small yet faint ink stain on your finger which tells me that you write. There's also a tuning fork in your satchel's side pocket, which means you also play, in your case the piano. Which you play only when you write down the music notes to your plays. And your suit tells you have been hired by a very known theater. You could be a composer, but your fingers aren't exactly one with musicians, so you write plays. You have also traveled to Paris, your jacket smells of wine which is a known mark in Paris."

"Amazing." the guest said. Dawson chuckled at that. Those were his words when Basil told how he knew he was a surgeon from Afghanistan. "But now that you mentioned it. I did hear a sweet melody when I got here. You said your niece played it?"

Basil suggested ask Elizabeth to come just in case. "So you are hereby a case, mister..."

"Wenmice, Andrew Wenmice." The guest introduced himself. "Yes, it is. But I'm afraid I can't tell you about it here. I was asked if you could come with me to the Royal Albert Hall, where we could talk about it."

"The Royal Albert Hall?" Dawson asked. "Only the best plays are shown there."

"I take then, whatever the case is, you don't want the public to know about it, so they won't panic." Elizabeth said as she came to the lounge with her violin.

"Allow me to introduce my niece, Elizabeth." Basil introduced.

"Please to meet you." Andrew said to Elizabeth. "Did you write that melody you just played a while ago?"

"Actually I played it for fun." Elizabeth said.

"I see…" Andrew said. "Mind if you come along. I think I could use that in my new play."

Elizabeth looks at her uncle who gives an approving nod on that.

It took some time to get to Royal Albert Hall. In the mouse world, Royal Albert Hall was one of the elegant communities in Mousedom. Since it was built in 1871 and used for big occasions, mice had used its basement and cellar without any humans noticing it. Mice had not only theater there, they had a fancy hotel and apartments for important visiting actors.

Mister Wenmice took Basil, Dawson, and Elizabeth straight to the theater. On stage, actors were preparing to practice one scene of the play, which Basil quickly recognized as Hannibal.

"Wasn't it shown in the Square theater a month ago?" Dawson asked.

"Well, you see… the play I'm writing is based on an opera house, so we are playing the plays that appear in it, Hannibal is one of the plays." mister Wenmice explained.

"A play about an opera house? Hmm…" Basil thinks out loud. "Elizabeth, why don't you stay to watch the rehearsal."

"But I want to hear what is the case." Elizabeth said.

"You could be my eyes while we talk." Basil whispered to her. In this, Elizabeth agrees and goes to sit in the front seats.

Meanwhile, Basil and Dawson followed mister Wenmice to the manager's office. There was an elderly mouse couple, By the rings on theirs, they are a married couple. The gentleman was probably ten years older than the doctor. He seems to be in good health and in good shape. A good quality suit could mean he is the manager of the theater. His wife was an elegant wise looking woman. Kinda reminds Basil of his mother. She obviously helps her husband with the theater and obviously has been in a few acts herself in her youth.

"Mister Basil, I'm so glad you two came here." Elder mouse said. "I'm John Smith, manager of the theater. This is my wife Helen."

"Please to meet you, Mr. and Mrs. Smith." Basil said as he greets them. "I understand that you have a case for me."

"In a way we do." Mr. Smith said. "However, we try to keep it inside the theater. If the public knows about it…."

"I understand," Basil said.

"What is the case?" Dawson asked.

"Do you know the story of Phantom of the Opera, mister Basil?" Mrs. Smith asked.

Dawson was surprised by the question, but Basil smirks at that.

"Are you referring to the rumored story in Opera Populaire in Paris?" Basil asked. "The one that happened one year before the Royal Albert Hall was built."

"So you know it?" Mr. Smith asked.

"I studied its articles when I was in university." Basil said. "In 1870, the opera Populaire's old manager retired and two new managers took over. At that time a new leading soprano was discovered, Christine Dae. After some time a new play was set. The managers try to please the former leading soprano by giving her the best part, while the new one gets a silent role. On that night, many things happened. The leading soprano started to sound like a toad, the stagehand was found hanging in the middle of the ballet and the chandelier fell off. That's when rumors started about the Phantom of the opera. Then after the new year ball in 1896, a new play was set. At that time of play, the Phantom was revealed and opera Populaire burned down, but Phantom was never found."

"Well, yes. That's how humans saw it." Mr. Wenmice said. "However the local mice learned the true story. The Phantom was actually a man with a disfigured face, which he had ever since he was born. He was very talented in many things, mostly in music. But because of his looks, everyone feared him. He lived under the opera house. And when the opera house burned, he escaped right before they found his hideout. The only thing left was his mask."

"So, that's why you were in Paris." Dawson said.

"You're planning to write the play of the Phantom of the opera." Basil said.

"Well, we mice know the real story. I thought it wouldn't hurt to make it into a play." Mr. Wenmice said. "Or so I thought…"

"You see, detective, three weeks ago strange things started to happen here." Mr. Smith said. "Setting accidents, misplaced items, and most of all we got this..." he said and showed the letter.

Basil takes it and reads it out loud. "Gentlemen, I take, you have come to realize who is behind all these incidents. I'm only asking for two things; that you keep box six empty for me and pay two thousand pounds a month, otherwise terrible things will happen. By yours truly O.G." Basil thinks for a while. "These are the same demands Phantom of the opera had back then."

"Exactly." Mr. Smith said. "Of course, I didn't believe it at first, but a few days ago our visiting soprano almost got injured."

"You think someone is pretending to be Phantom and demands money?" Dawson asked.

"How many people know about this?" Basil asked.

"Me, my wife, and Mr. Wenmice." Mr. Smith said.

"And the leading soprano and her understudy. She is from Paris, so she knows the story." Mrs. Smith said.

"Leading soprano from Paris?" Basil asked, looking surprised.

"I'm sure you know her. The famous Mademoiselle Rel…" Mr. Smith tried to say before Basil hurried out of the office. "I take he knows."
