Upstairs in the flat of Sherlock Holmes, Basil pushed open the small wall design and checked to see if the coast was clear. When it was, he pushed the little door open, and the three mice stepped in Holmes' apartment.

Rosa: Hmm. Nice furniture. Could use a woman's touch, like yours should.

Basil: Come here, Toby! We have a case!

Thundering footsteps approached them, shaking the ground. When they looked up, there stood Toby, wagging his tail and panting happily. Toby gave Basil a friendly lick and Basil wiped away the dog's saliva.

Basil: Blech!

Toby leaned down so he could sniff at Rosa. She patted him on the nose.

Rosa: Aw, you're so adorable!

She realized what she just said and she glanced over at Basil and Dawson, both giving her puzzled looks. But when Toby sniffed Rosa, he growled at her.

Rosa: Ok, I take it back! You're so terrifying!

Basil: (pushes Toby back) Toby, stop that!

Rosa hid behind Dawson, trembling.

Dawson: Don't worry, Miss Spellcove. That's exactly how my first meeting with Toby went.

Basil: Sorry Miss Spellcove. Toby has an excellent sense of smell and can track anything. But he's really friendly I assure you.

Rosa: Hehe. Real friendly alright.

Basil: (amused smile) You afraid of dogs, Miss Spellcove?

Rosa: Huh? No! I wasn't scared at all!

Basil chuckled. He knew he was right and Rosa was scared of Toby.

Rosa: Now, shall we go to the Royal Academy?

Basil: Of course.

Toby laid his head down, his ear turned into a little staircase, and the three mice climbed up to get onto Toby's back.

Basil: To the Royal Academy!

Toby got up so suddenly that three mice nearly fell off the dog's back, so they held onto the dog's leash as Toby bolted out the door.

A few moments later, Toby arrived at the Royal Academy. He lay his head down so the mice could get off. Rosa was the last to get off. Toby gave a deliberate sniff and Rosa fell off, into Basil's arms. For a moment, the two stared at each other, and then quickly separated. Basil cleared his throat and Rosa blushed. Dawson seemed to notice this and he grinned.

Basil: What are you smiling at, old man? Let's go inside.

There was a small hole in the wall of the building and the three mice went inside. A guard was at the entrance, and he let them passed when he recognized Basil and Rosa.

Guard: Good evening Miss Spellcove, and to you Mr. Basil. The director is waiting for you.

Rosa: Thank you.

When they entered a large room full of beautiful paintings, they met the art director, who stood by the wall where a portrait used to be.

Director: Ah, Mr. Basil. Good to see you can make it. Lady Caroline was most anxious for your arrival.

Rosa: Where is she, Director?

Director: She went home, Miss Spellcove. She had things to attend to.

Basil: It's a shame. I was hoping I'd meet the lady. Now, let's hear about the facts.

Director: It was a few days ago that Miss Spellcove finished the portrait of the lovely Lady Caroline, and it was here that the painting was hung up so everyone could look and admire the lady's beauty. But last night, someone broke into the museum and stole the painting. One of the guards spotted him trying to escape with the painting, but he crashed through a window to get out. Although we don't know how he got inside. Lady Caroline didn't want the public to get word of the theft as to avoid scandal. It was she who asked to have you investigate this case, Mr. Basil.

While the director was talking, Basil took out his magnifying glasses and examined the wall to find any clues.

Basil: What time did the theft take place?

Director: A few minutes after 12:00. The guards never heard a sound when the theft occurred.

Basil: Did the guards see what the thief looked like?

Director: No. It was very dark and he hid himself completely well in the shadows.

Then Basil spotted a tiny piece of purple cloth stuck to the wall.

Basil: Hello. What have we here? (takes the cloth)

Dawson: What did you find?

Basil: A small piece of cloth.

Rosa: (recognizes the cloth and gasps) Uh, perhaps the cloth came from a man's cape or a woman's cloak.

Basil: No. If it did, it wouldn't have a strange smell. (sniffs the cloth) A very disgusting smell too. With this cloth, we could find the hideout of our thief and where he has taken the portrait.

Rosa: But how are you going to find the thief's hideout with just a small piece of cloth?

Basil: We shall go back to Baker Street and do a little chemical analysis.

Dawson: I was afraid you were going to say that. (whispers to Rosa) His experiments can get a little out of hand, my dear.

Basil: My dear Director, please inform Lady Caroline that we shall find the painting and return it to the Academy in no time.

Director: I knew you would find something, Mr. Basil. I'm glad the lady contacted you.

But Rosa was secretly worried. She had to get that cloth away from Basil before he could use it to track down the painting and the hideout.

On their way to the exit, Basil noticed a small hole in another window. He examined it carefully and his eyes lit up.

Basil: So this is how he got in.

Dawson: What are you talking about, Basil?

Basil: This hole in the glass. Our thief used a glass cutter to get inside the building. Once the hole was complete, the thief would reach his hand through the hole and open the window to get inside. But he didn't have time to escape through the window he got in from, so he crashed out through another window in his haste to avoid capture.

Director: Why, I never noticed it!

Rosa: (mutters) How clumsy can Fidget be when he leaves something behind?

Basil: Did you say something, Miss Spellcove?

Rosa: Oh! Uh, nothing. Nothing at all. Shall we go?

An hour later, the three mice were back at Baker Street. Basil set down his microscope and examined the cloth while Dawson and Rosa looked over his shoulders.

Rosa: What are you doing?

Basil: Under the microscope, the cloth will reveal a lot about the thief to us. There's a bit of dirt on the scarf and that strange smell of Rodent's Delight.

Dawson: How do you know it's a scarf?

Basil: I recognize the cloth on the scarf. It's old, seen better days, but the owner still wears it. The dirt on the scarf shows the thief had come from Oakley Street. And that disgusting smell is….(sniffs the cloth) How peculiar. It's like déjà vu.

Dawson: Bless you.

Basil: No, no, no. Déjà vu means I've seen this before, so I know the smell. It's from Rodent's Delight. Remember the time when we examined that list Fidget used to steal toy uniforms and gears, it contained the smell of Rodent's Delight from the Rat Trap pub….No, it couldn't be. Could it?

Dawson: What's wrong, Basil?

Basil: Dawson, you don't suppose our old peg-legged friend Fidget could be behind the theft of the painting, do you?

Dawson: But that can't be! Fidget drowned in the Thames River. Remember?

Basil: I know, but it all seems clear. The scarf and the smell of his favorite drink. That's Fidget! And if Fidget is alive, then that means….

Dawson: Basil, you can't mean that Ratigan could be alive as well. We saw him fall from Big Ben to his doom. There's no way he could survive that fall.

Basil: Perhaps. But we'll worry about that later.

He took the piece of scarf to his chemistry set. Rosa looked worried. She had to get that cloth away before Basil could use it to find the location of the hideout. There was a knock at the door and Mrs. Judson answered it. A delivery boy handed her an envelope. It was addressed to Basil.

Mrs. Judson: Uh, pardon me gentlemen, but there's a letter for Mr. Basil.

But Basil and Dawson ignored her. Basil was about to light the cloth on fire.

Mrs. Judson: THERE'S A LETTER FOR MR. BASIL!

Basil and Dawson were so startled that they nearly tripped. Basil dropped the cloth he was holding.

Basil: Do you mind, Mrs. Judson?! We are busy with an analysis!

Mrs. Judson: But you have a letter from Clifford!

Hearing that name, Basil took the envelope, opened it, and read it. Mrs. Judson went back to dusting the furniture. When no one was looking, Rosa saw this as her chance to take the cloth and hide it in her bosom. Mrs. Judson dusted the chemistry set and put some old papers in the waste bin.

Dawson: Basil, who is this Clifford?

Basil: Why, didn't I tell you? He's my older brother!

Dawson: What? I didn't know you had a brother.

Rosa: You never mentioned having a brother.

Basil: Oh? That surprises you two? There's no greater genius than my brother Clifford. And if you're wondering why you never heard of him, that's because he wishes his name to be kept secret from the public. He doesn't care much for solving crimes, he likes to reside at the Diogenes Club, and he works for the British government, which means he's an acquaintance of the Prime Minister.

Dawson: Amazing!

Rosa: What does your brother want?

Basil: Clifford writes like a drunken crab, I find it hard to understand what he wrote to me.

Rosa: (takes the letter) Let me see. The letter came from Oakley Street, and the letter reads, "My dear brother, I'm sure you heard of the Duchess of Mousemouth, a charming woman who has escaped from attempted robbery or homicide, by either luck or wit. But today, the most intriguing problem has occurred concerning the Duchess. But it's not about homicide, its robbery. She wishes to consult with you as soon as possible. Sincerely, your brother Clifford."

Basil and Dawson stared at Rosa in amazement. They didn't understand Clifford's handwriting, but Rosa did.

Basil: How did you understand all that?

Rosa: Let's just say I have my own intelligence.

Dawson: Astounding! Isn't that right, Basil?

Basil: Eh, whatever.

But he was secretly impressed. Turning his attention to the cloth on the chemistry table, he found it gone.

Basil: Where's that piece of scarf?

He began searching under the tables, the chairs, everywhere. Rosa snickered, watching Basil search for that silly piece of scarf when she had it in her bosom the whole time.

Basil: Where is it?

Dawson: I don't know. Ask Mrs. Judson, she was cleaning the chemistry set.

Basil: MRS. JUDSON! (Mrs. Judson comes in) Am I right in assuming you wiped the dust in here?

Mrs. Judson: I cleaned everything, Mr. Basil.

Basil was starting to get irritated. Dawson backed away while Rosa stood by, looking innocent.

Basil: Also, you removed something from my desk?

Mrs. Judson: Only scraps of paper and-

But Basil jumped into the waste bin, searching for the piece of scarf. He tossed pieces of garbage everywhere as he searched. But he found nothing.

Mrs. Judson: What on earth are you doing?

Basil: Searching for the piece of cloth you tossed in the waste bin!

Mrs. Judson: I didn't find a piece of cloth! It wasn't there when I dusted the table! But to me, pieces of cloth belong in the waste bin!

Basil: But to me, that piece of cloth was evidence we found at the Royal Academy where the theft of Rosa's portrait had taken place!

Dawson: Now Basil, there's no need to take it out on Mrs. Judson! If she didn't take the cloth, it must've fallen to the floor!

Basil: I searched everywhere Dawson! It's not like it can just get up and walk away!

While the three mice argued, Rosa stood silently nearby. While she was pleased to get the cloth away, she began to feel a little bad for letting Mrs. Judson get the blame. She had let her inside Baker Street after escaping a hungry cat and after getting wet by a motorcar, and was kind to her, just like her old nanny was to her when she was a child. Rosa stepped towards Basil and shook her finger at him.

Rosa: Now look here, Mr. Basil! You can't just take your frustration out on your own landlady just because you lost a piece of a scarf we found at the crime scene! If she doesn't know where it is, than she didn't throw it out! But I'm sure it will turn up when we come back from Oakley Street to investigate the problem your brother's involved with. I suggest we go and visit your brother to see what he wants.

Basil was taken aback. No woman ever stood up to him like that before, nor showed how to read a letter he couldn't understand.

Basil: I suppose your right, Miss Spellcove. Come Dawson, lets us go see Clifford. Miss Spellcove, stay here.

Rosa: Oh? Why can't I? Is it because you don't want a female to get in your way?

Basil: I never said that. Because it is a man's job to investigate-

Rosa: There you go again with the man thing. Need I remind you that I am not a girl to be trifled with? I wish to investigate this matter because I might be involved as well.

Basil: Whatever do you mean?

Rosa: First my painting is stolen and now your brother calls asking for help. And you said the dirt on that scarf came from Oakley Street, so whoever took the painting must have done something at the household of the Duchess of Mousemouth.

Dawson: She has a point, Basil. She could be involved in this other matter.

Basil: So I see. Very well, Miss Spellcove, you may come. But just try not to interfere.

As they headed for the door, Dawson and Mrs. Judson looked at each other, and then at Basil and Rosa.

Dawson: What do you think she meant by man thing?
