Hey there, this is my first The Great Mouse Detective fanfic, and I hope you like this one.

Aggie, Wyatt, Skylar, the three cops, three stray mice, and the waitress belong to me

Basil, Dawson, and Mrs, Judson belong to Disney

In London, a teenage white mouse with brown eyes and long black hair name Aggie travel alone in the street with her suitcase. She wore only a plain white dress, and eyeglasses. It was raining on the streets as Aggie has no where to stay. She found a house that was named 221 Baker street. She thinks she can stay there for the night as she knocks on the door, where Mrs. Judson opened the door.

Aggie: Good evening, Madame.

Mrs. Judson: Good evening. How can I help you?

Aggie. Um... I just came here in, I'm also new here, and I don't have a place to stay. So if you don't mind that I can stay here for the night? It's freezing out here when it rain.

Mrs. Judson: (Concerned) Oh my! You poor dear! Quickly, get inside. (She dragged Aggie and the suitcase inside, and lead her to the couch) You must be tired, chilled, and hungry. But, I know how to fix that. Let me fetch a pot of tea and some cheese crumpets. (She rushes to the kitchen and shuts the door.)

While she was alone, Aggie looked at around the room, so fascinated. It's like a laboratory or a table that students doing their homework. She thinks that the owner of the house is a very busy person. Just then, she heard a voice coming from the front door.

Basil: No, no, no, Dawson, I am not going have a dinner party with the cops in my house tonight. I'm very busy!

Aggie quickly hides behind the couch as Basil and Dr. Dawson entered the room.

Dawson: But Basil, the police really want to congratulate you after you saved the queen, and defeated Ratigan.

Basil: I just want to rest before any clients approach me for another case tomorrow, and I sense someone is spying on us here in this room, right now.

Dawson: Whatever did you mean? There are only two of us here in this room, Mrs. Judson is… (sniffs) making some cheese crumpets, and I only see a white string behind your couch.

Basil: It's obvious, Dawson, (pointing wet footprints on the floor) I noticed there are wet footprints on the floor before we enter, (pointing a red suitcase besides the couch) a red suitcase, which I never had one, is besides my couch, (pointing the white string) and this is no white string… (grabbing and pulling the white string, which it was actually a tail, from the couch, and hanging Aggie upside down)

Aggie: Waaahhh!

Basil: A strange white spy mouse!

Aggie: (chuckled and smiled sheepishly) H-hi there.

Basil: Mrs. Judson!

Mrs. Judson rushed out from the kitchen.

Mrs. Judson: Oh, Mr. Basil, you're home! (gasps) Hey, put our guest down!

Basil: Guest? (dropping Aggie down with her head on the floor)

Aggie: (straightening herself by putting her feet on the floor, and rubbing dirt off from her body) Hey, you can't just dropping someone who was new here! Look, it wasn't her fault I entered here, I just want a place to stay.

Basil: Everyone is welcome in my home, but I never expect of having a guest staying here.

Mrs. Judson: (scolded) Mr. Basil, I know a detective like you likes to help people, but why can't you help this poor little girl.

Basil: I only help people when there are problems, losing things, and cases, not letting this girl stay in my house.

Dawson: Now Basil, I know you're quite stubborn, but you can't let this girl freezing outside. She can only stay here for the night.

Aggie: (begging as she hugged Basil's leg) Please sir, I'll stay for just one night, and I'll leave tomorrow. I promise. (Her eyes transformed into cute puppy eyes)

Basil: (grunted and rolled his eyes) Alright! You can stay. (Aggie hugged Basil tightly) Just tonight.

Aggie: Oh thank you, thank you, thank you, thank you.

Basil: (removing Aggie off of him) We have an extra room for guests (to Mrs. Judson as he gently pushes her back to the kitchen) Now, why don't you make us some dinner?

Mrs. Judson: But, but, but…

Basil shuts the door, silencing her as he gets back to his studying table

Basil: (To Aggie as he removed his brown coat) So, you belong from another world, aren't you?

Aggie: Yes (Puzzled) Wait, how did you know I'm from another world?

Basil: Glad you asked. You see, your clothes are too modern, you carried a type of remote control that can open portals to different dimensions, your suitcase is made of plastic, your behavior is more of a human than a mouse, and you carried an ID around your neck that shaped with a letter "I" with your picture in it, specifically you're the leader of your team.

Aggie: (fascinated) Wow, very smart.

Basil: Actually, it's elementary, my dear Miss… um…

Aggie: Galido. Agatha Galido

Basil: Yeah, whatever. Nice to meet you.

Mrs. Judson: (opening the door from the kitchen) Dinner time!

Aggie: Yeah!

Aggie rushed to the kitchen for dinner. Dawson followed her, and Basil sighed and walked to the kitchen. Suddenly, a knock from the door interrupted him. Basil walked towards the door, and opens the door, revealing four cops.

Wyatt: Good evening, Mr. Basil

Basil: Good evening, Sir. Wyatt. What brings you guys here?

Cop #1: I thought we're having a dinner party to congratulate you for your… heroism.

Basil: Yeah, well, I have other plans (referring to Aggie, who was eating dinner with Dawson and Mrs. Judson)

Aggie: (sniffs) Hey, is that Montblanc Legend I smell?

Wyatt: Yeah, Montblanc Legend is one of my favorite colognes.

Aggie: Oh, mine as well. It's masculine and yet soft with the barest hint of floral notes and—

Basil: You can stop talking now!

Wyatt looked inside the house.

Wyatt: Ooh, nice flat.

Basil: Why, thank you.

Wyatt: This is how you've became a great detective. I wish I can have this. (clears throat) Well, we better go. Have a nice dinner. (He and the other cops walked out)

Basil: (closes the door) Well, that was a short visit. (He walked to the kitchen)

The next day…

Basil: Miss Agatha, you should be leaving ten minutes ago!

Aggie: (running down the stairs with her suitcase) I'm coming! Wow, you really want me to leave. Hey, where Mrs. Judson?

Dawson: Mrs. Judson's sister sent a message that she was sick. She had to leave to take care of her.

Aggie: (gasps) Oh, no! I hope her sister's okay!

Basil: Me too.

Just then, a knock was heard coming from the door. Aggie rushed towards the door, and opened the door, revealing a female adult brown mouse with blue clothes and hat, and Wyatt and other three cops behind her.

Aggie: Hello there! How can we help you?

Skylar: Hello, my name is Skylar, and I'm here to find my sister.

Dawson: Oh dear, do you lost your sister? Was she taken?

Skylar: No, but I remembered that she worked here.

Aggie: Ooh, you're Mrs. Judson's sister. But I thought you were sick.

Skylar: What?

Aggie: Well, Mrs. Judson got a note from you saying you weren't feeling well, and she went home to take care of you.

Skylar: I didn't send a note.

Aggie: That's so strange.

Basil: Miss Skylar? Aren't you supposed to be sick? Okay, what's happening?

Skylar: I don't know. But I do know I didn't send my sister a note.

Aggie: Could someone have sent Mrs. Judson a fake note?

Cop #2: Who would do such a thing?

Dawson: Someone who wanted her out of here, I suppose.

Basil: Why would anyone want that?

Wyatt: Maybe so they could get rid of her.

Wyatt and the other three cops glared at Basil as Basil looked nervous and scared, and Dawson, Skylar, and Aggie's eyes widened in shocked and gaped.

Basil: Me?! I would never do that to Mrs. Judson! Why would you think it was me?

Cop #3: I heard that you're scolding Mrs. Judson about welcoming a stranger in your house.

Basil: But I already allowed her to!

Cop #2: And you don't want to be disturb during your work

Basil: Yeah, but not all the time.

Cop #1: I saw Mrs. Judson walking out of your house at around midnight. Where were you then?

Basil: I was asleep at midnight.

The cops gathered around for a short talk, leaving Basil confused.

Cop #1: (To the two cops) You two, head over to Skylar's house and try to find Mrs. Judson and bring her back. (To Basil) I have to warn you, if you sent that letter, the bylaws are clear. I'd have no choice but to arrest you. Understand?

Basil: (sighs) I understand. (To Dawson) I want find something to prove that I didn't make that fake note to Mrs. Judson.

Wyatt: Whoa there, Mr. Basil, you can't solve this case.

Basil: What do you mean?

Wyatt: This is your case. You can't solve your own case. Probably you could fake your investigation to prove you're innocent

Basil: If that's what you think, then how am I gonna prove I didn't send a letter that I didn't send?

Aggie: With me! (Aggie came out from the shadows with a Deerstalker cap and a brown coat, which they were belong to her) Detective Aggie is on the case, and we are going to get to the bottom of this faster than my costume change!

Basil: Yeah, what's with the getup?

Rarity: Obviously, I am channeling Sherlock Holmes and Sam Spade through these detective clothes and attitudes, and they would say that the best way to prove that you didn't send the letter is to find out whoever did.

Basil: (scoffs) Why should you do this case? You're not even a detective.

Aggie: Well, since you can't solve your own case, who would? The cops? Not a chance.

Basil: There's no way in this world that I'll allow you to solve this case.

Dawson: But Basil, what if she's right? If this case will not be solve in time, and everyone thought you did it, you'll be behind bars.

Basil: (calming her temper, and sighed in defeat) Alright, (To Aggie) but you better know what you are doing. Take it seriously.

Aggie: Got it! First stop – the scene of the crime!

As noir music plays, Basil, Dawson, and Aggie walked towards Mrs. Judson's room

Aggie: (narrating) We had a long road ahead of us, Mr. Basil, Dr. Dawson and I. Well, not too long because we didn't have much time, but the point is... I was up for the challenge.

In Mrs. Judson's room, Basil, Dawson, and Aggie search for clues.

Aggie: (narrating) There I was, surveying the crime scene, and looking stylish for the first time while doing it. (With her magnifying glass, she saw an envelope under the door) This must be the envelope for the letter Mrs. Judson got! (sniffs the envelope and shook it upside down, dropping short strands of light brown hair on her hand) Hmm. These look like hairs from a light brown mouse's hair!

Basil: (gulps) That's not good.

Aggie: (narrating) Mr. Basil was getting antsy, but I had faith I could clear his name and find the real culprit.

Basil: What are you doing?

Aggie: (stammers) Uh, just thinking thoughts. (narrating, opening the window, looking outside) Mr. Basil was right. In order to solve the mystery, we had to be focused. Driven. One hundred percent in the— (normally speaking as she saw a newspaper besides the window) Ooh! They fixed the hole of the Big Ben already?! Why, that's good-

Basil: We don't have time to look at the news! They're gonna arrest me unless we solve this thing!

Aggie: I know, Mr. Basil, and I'm on this case like a charm on a bracelet! Here's what I'm thinking: someone had to bring Mrs. Judson that letter, which means someone must have seen them! (Pointing three gray stray mice outside)

Basil, Dawson, and Aggie brought the three stray mice to the dark alley, where they placed them in chairs

Aggie: I just have a few questions for you, and I'm sure once we get some things cleared up, we'll—

Basil: Come on, Miss Agatha, we don't have all day! (to a stray mouse #1) Where were you on the night of last night at midnight?!

Stray mouse #1: We were here, guarding the streets like we were supposed to. We also saw Mrs. Judson last night

Basil: A likely story.

Stray Mouse #1: I'm telling you, we were there all night at the street, and, except Mrs. Judson, no one went in or out of your house.

Stray mouse #2: Except for you.

Basil: What are you trying to say?!

Stray mouse #2: I know you went from your case last night, but the only mouse who was out last night, besides Mrs. Judson, was you.

Basil begins to shaking in panic as Dawson tries to calm him down

Aggie: (narrating)The waters were getting choppy. Mr. Basil's tactics were, well, horrid. It was time for another approach. (normally, dressed as Lemme Fatale) Perhaps I should take it from here! (To the three stray mice) You stray mice have such miserable lives. I'm guessing that at times it can be rather... miserable.

Stray mouse #1: It is. I've always stretched out my cup to beg for money!

Aggie: And of course being a strays can be dirty and poor. I'm not saying you did, but if someone gave you some treats or prizes, you more than deserved it.

Stray Mouse #3: Oh, you're right. We don't get a lot of things we have wanted.

Stray Mouse #2: Except for last night when someone was nice enough to leave a box of doughnuts and three cups of coffee for us. So we did take them when we ate those doughnuts.

Aggie: What kind of order is that?

Stray Mouse #2: Special.

Aggie: How special?

Stray Mouse #1: A box of vanilla, chocolate, and strawberry doughnuts, and free three cups of coffee.

Aggie: Was the tops of the doughnuts decorated with colorful sprinkles?

Stray Mouse #3: It was.

Basil: Ugh, who cares how it was decorated?!

Aggie: (narrating) Mr. Basil was questioning my methods. But I knew what I was doing.

Basil: Do you?

Aggie: Oh, oh, oh. Did I say that one out loud?

Basil: I mean, even I think I'm guilty at this point! (Kneeling down in front of Aggie, and looked up to her) What if I wrote that note when I was asleep?! Do you know what I do when I sleep?! Because I sure don't!

Aggie : Oh, calm down, Mr. Basil. We'll get to the bottom of this. There's only one bakery in London that makes a special order of doughnuts with free three cups of coffees and that's...

Dawson: The Mousent Doughnut and Coffee Shop!

Basil, Dawson, and Aggie arrived at the Mousent Doughnut and Coffee Shop as Aggie now wore a fancy dress with her hair tied in ponytail.

Waitress: Hello, how can I help you?

Aggie: I've heard you have the special order of doughnuts with free three cups of coffees here!

Waitress: Ah, you travel in the right circles! We have the only special order of doughnuts with free three cups of coffees here! (pointing the window with many special orders, but one plate of the special order is empty)

Aggie: Oh, no. But someone's already bought it! Who was the lucky mouse?

Waitress: I can't even say!

Aggie: Why? Because it was someone famous?

Waitress: No... because it was hard to tell! He was wearing a trench coat, sunglasses, and a scarf around his head that covered most of his face. But I do remember he had a really deep, serious voice.

Basil: What do you mean, serious?

Waitress: Well, kinda like yours.

Basil gulps and sweats as Dawson patted Basil's shoulder

Aggie: If there's anything else you can remember.

Waitress: Well, have I got a story for you! The mouse who bought the box of doughnut with three cups of coffee threw a big fit when he accidentally got a half-spilled coffee on his scarf!

Aggie: That's terrible! What color was the scarf?

Waitress: Yellow, I think

Aggie: You don't say!

Basil: I can't believe you're talking clothes at a time like this!

Dawson: Basil, don't panic.

Aggie: Yeah, I need you to trust me.

Basil: (frustrated) Trust you?! You've spent more time changing clothes and talking about food than trying to help me! I'm doomed!

Aggie: No, you're not! Come on!

Aggie walked out with the gentlemice. Dawson followed her, but Basil still glaring at Aggie, but followed her anyway. As they walk on the sidewalk, the rain pours. Dawson and Aggie opened their umbrellas, but Basil remained wet, as he shook his head in shame or guilt that he thinks he is the one who sent the fake letter to Mrs. Judson

Aggie: (narrating) Mr. Basil was obviously upset, but I had all my ducks in a row. He was not going to like it, but there was only one way to find out if my suspicions were correct.

At the Baker Street, the two cops arrived at Basil's house, while Wyatt, Cop #1, and Skylar were waiting.

Cop #2: We looked everywhere, but Mrs. Judson wasn't at her sister's house!

Skylar: (worried) Where could she be?

The door opens as Basil, Dawson, and Aggie arrived.

Aggie: I have found the culprit! Someone sent Mrs. Judson away and framed Mr. Basil for it. And that mouse was none other than...Wyatt!

Everyone in the room gasped, but Basil face-palmed in embarrassment.

Basil: (outraged) Miss Agatha, I can't believe you would accuse Wyatt of framing me! He's a cop, for heaven's sake!

Aggie: All the evidence points to him!

Basil: (scoffed) What evidence could you possibly have? All you did was ask about doughnuts and coffees, checking the newspaper, and change outfits a gazillion times!

Aggie: Let me explain. I never believed you would send Mrs. Judson away. When we found the light brown hairs in Mrs. Judson's room, (showing a plastic bag with Basil's light brown hair in it) I could tell they didn't fall out. They were cut! No mouse loses hair in a chunk. And look at the ends. It's a straight line! They were clearly cut with shears. Then when we were examining Mrs. Judson's room, I smelled something on the envelope. Montblanc Legend, Wyatt's cologne of choice. Then, outside Mrs. Judson's room window, I noticed a newspaper besides the window, indicating that someone had been hiding behind them! Perhaps after they dropped off the fake letter?

Wyatt: Montblanc Legend is a very popular fragrance, and anyone could have hide behind that newspaper.

Aggie: Precisely why I questioned the three stray mice. They were sitting on the sidewalks at the streets all night, except for a small window of time when someone brought them a box of doughnuts and three cups of coffee. A box of doughnuts and cups of coffee that was ordered by a mouse with a serious voice. Whoever ordered the doughnuts and cups of coffee got a coffee stain on his yellow scarf, and I couldn't help but notice that Wyatt is tied in a tight Windsor knot instead of its usual loose slipknot! And why is that? Is it to hide… (untying the scarf, revealing the coffee stain on the scarf) …the coffee stain?!

The cops, Dawson, and Skylar gasped

Wyatt: This is just ridiculous! (To the cops) Everyone, you don't believe a word of this, right?

Aggie: (angrily) Just admit it! You're as guilty of framing Mr. Basil as you are of ruining that yellow scarf!

Wyatt: Ah, fine! You caught me! I did it!

Basil: But why, Wyatt?! Was it because I didn't invite you to my dinner last night?

Aggie: (interrupts) No. It was because he always wanted to get your flat. I heard him commenting Basil's flat last night during our dinner. (To Wyatt) That's the polite but disingenuous comment you make when you want to seem happy but really you're not.

Wyatt: I thought if I could get Basil arrested, the flat would be mine.

Basil: Really? You're despicable. And I thought you were the good cop ever. Until now.

Dawson: Which reminds me, where is Mrs. Judson?

Wyatt: I sent her the letter pretending to be Skylar. I told her I had diarrhea, and the only cure is in Canvey Valley.

Dawson: No wonder she's been gone so long. Canvey Valley is so far away from here! She had been travel for so long.

Basil: Then we better get her back before she gets lost. (rushing to the door, and calling Dawson) Quickly, Dawson, we've not a moment to lose!

Dawson: Coming Basil!

The two mice rushed outside

After a few hours, cops #1 and #2 were calming Skylar, Cop #3 looked at the window, waiting for Basil and Dawson, and Aggie kept glaring at Wyatt.

Cop #3: Basil is still gone!

Aggie: Oh, don't panic. If I know Mr. Basil, which I knew him just yesterday, he'll come through.

The door bursts open to reveal Basil and Dawson arrived with Mrs. Judson.

Skylar: Sis, you're back! (rushing towards Mrs. Judson, and hugged her) I thought you would be lost.

Mrs. Judson: I would have, if Mr. Basil and Dr. Dawson hadn't found me so fast. They already found me before I went too far away from here.

Basil: (approaching towards Aggie) Miss Agatha, I couldn't have done it without you. (removing his hat off of his head and placed it on his chest in guiltiness) And I'm sorry I doubted you. But why didn't you tell me what you were doing?

Aggie: Well, I didn't want to get your hopes up until I was sure, and I couldn't be sure until I saw that coffee stain.

Basil: (guilty) Thank you for believing in me, even when I was doubting you. We got off on a rocky start, huh?

Aggie: Actually, we didn't. You've let me stay in your house, you've invited me to dinner, and you've let me solve your case.

Cop #1: (interrupts) I'm sorry to disturb you, but we have to apologize for this mess, and we'll take Wyatt to report this to the chief.

Wyatt: (glaring at Basil and Aggie) I will get you for this Basil, and that girl too.

The cops dragged Wyatt out, and closes the door.

Basil: (To Aggie) But why are you doing this for me? Even when I was so mean to you?

Aggie: To be honest, I'm not really a detective, but I only solve cases for a friend.

Basil: (shocked) You think I'm your friend?

Aggie: Uh… yeah. Sort of. Well, it's time for me to go. (dragging her suitcase with her)

Basil: (Stuttering) But, I thought…

Aggie: Well, like what I promised, I just stayed here for the night, and I help you with your case, I should go.

Dawson elbowed Basil as a sign for Basil to tell Aggie something.

Basil: Before you go Miss Agatha, I wanted to say to you that… About your detecting skills. (Aggie turned her head to him) You've done an excellent job, and you did it for me, so I was thinking… I want you to stay.

Aggie: (shocked) What?

Basil: You're pretty good at this, even you're not a detective. Your skills made me think that… I kinda need all the help Dawson and I can get, and I want you to join us in every cases.

Aggie: You mean, I can solve cases with you, and help you?

Basil: Well, if you wanna.

Aggie: (jumped excitingly) YES! (covering her mouth in embarrassment) Oh, yes, yes, yes. I do. I wanna. I can.

Dawson: (extended his hand to Aggie, and shakes hands with her) Well, welcome to the Baker street, Miss Agatha.

Aggie: Please, call me Aggie. And I'm looking forward to solve cases with you, Mr. Basil.

Basil: (extended his hand to Aggie) It's just Basil.

Aggie and Basil shook hands.

At the flat, Mrs. Judson served cheese crumpets for Basil, Dawson, Aggie, and Skylar as they chat and laugh.

Aggie: (narrating) So, the case has been solved. Basil's happy, Dawson's happy, Mrs. Judson's happy, Skylar's happy, I'm happy, everyone's happy. I guess I should stay here for a while to solve more cases, and help a friend. Since I need to improve my detecting skills, Basil gave me a book of "How to become a good detective". Although I hate reading, I still want to be a good detective as Basil was, and I thank him for that.

Basil: You're welcome, my dear.

Basil was sitting on his study task, while Aggie read a book on the couch.

Aggie: (chuckled in embarrassment) Oh, did I say that out loud?
