When Rosa regained consciousness, she found herself inside a dark and damp dungeon. The whole room seemed to be moving from side to side, making Rosa nauseous. Sitting in front of her was a little girl with a red, dirty dress and with a red bow on the left side of her ear, also dirty. The little girl's hands and feet were tied up. She could see Rosa didn't look too well.
Olivia: Are you alright?
Rosa: Not really. I feel nauseous. Hey! Where did you come from?
Olivia: I was captured by that ugly bat! He took me away from my daddy while we were out in the park!
Rosa: Well you and your daddy should've been more careful when you're out alone in London. You never know when some alley cat or a ruffian will come out after you…Wait a minute. What bat?
Olivia: Fidget, that ugly, one-legged bat! Basil helped me find my daddy when he was kidnapped, and we've been friends ever since.
Rosa: You know Basil of Baker Street?
Olivia: Yes!
Rosa: Well, let me tell you something sweetie, Basil may be a great detective, but he's stubborn, arrogant, bad tempered-
Olivia: Why would you say that about him?
Rosa: He says it's my fault Doran escaped from him and that I should never have went with him to the East End! That's why I left Baker Street! Who does he think he is anyway?
Olivia: He's the Sherlock Holmes of Mousedom!
Rosa: That wasn't an actual question! Oh, forget it! What do you know? You're just a little girl, you wouldn't understand!
She was still angry and hurt after running away, but was now frightened at being in this dungeon with a little girl who spoke with a Scottish accent, and was as frightened as she was. Who knows what will happen to them. Who knows what those kidnappers will do to them.
Olivia: What's your name?
Rosa: Rosa Spellcove.
Olivia: My name's Olivia Flaversham. How did you meet Mr. Basil?
Rosa: I asked him to find a painting I made of Lady Caroline, my employer. Then the Duchess of Mousemonth's necklace was stolen, and the mace from the House of Commons was stolen too. All three items were stolen by the bat with the wooden leg.
Olivia: Daddy and I heard about the mace and necklace, but nothing about your painting.
Rosa: Who is your father?
Olivia: Hiram Flaversham, a toymaker. He makes such wonderful toys, and he's the kindest, nicest daddy in the whole world!
Rosa smiled. The look of love and admiration in the child's eyes reminded her of herself when she was a child, and she used to say the same thing about her father.
Rosa: And what about your mother?
Olivia: (sadly) My mother passed away.
Rosa: Oh, I see. Well, I was close with my papa when I was your age. He was a good father, but when he lost his job here, we moved to Switzerland and he returned to London to get a better job. We haven't heard from him since. But a month ago, we got a letter from a friend of his that he had died. It was a real shock to me and mama.
Olivia: (puts a comforting hand on Rosa's hand) I'm sorry.
For a moment, the two girls smiled at each other.
Rosa: Olivia, if you don't mind my asking, why was your papa kidnapped?
Olivia: I told you my daddy was a toymaker. He makes mechanical toys. So Ratigan had him kidnapped and forced him to make a robot that looked like Queen Moustoria, so he can use the robot to fool everyone at the Jubilee that she was retiring and was having Ratigan rule in her place.
Rosa: (stammers) I…I see. Uh, I don't mean to ask this but, do you know why this Ratigan did all this?
Olivia: Mr. Basil told me that he used to be a teacher at Ratcliffe University, but he turned to a life of crime by stealing the Crown Jewels. He's been after him ever since and everyone in the city feared and hated him because he was a dangerous criminal. Even Mr. Basil called him the Napoleon of Crime.
Rosa stared at Olivia. She couldn't believe it. Her own father, Professor Padriac Ratigan, a villain.
Rosa: (to herself) I don't believe it! My own father, a criminal mastermind?! Would that explain why we left London for Switzerland? Would that explain why he never visited us?
Olivia: Are you ok, Miss Spellcove?
Rosa: Huh? What? Uh, I'm fine. (chuckles nervously)
Then they heard voices from above deck. Rosa recognized the voices as Fidget, Big Tuppy, and Russmer.
Fidget: I got the little girl just like the Captain said. But what about the pretty lady?
Big Tuppy: Everyone at the hideout is questioning her loyalty and the boss asked to have her brought back to the hideout. Somehow she left the place that snoop Basil lives at.
Russmer: I see. But you better watch out, nobody around here messes with that sleuth.
Big Tuppy: I mess with whoever I want to!
Fidget: So what are we going to tell the boss?
Big Tuppy: The boss will know what to do about the lady. Right now, it's the little brat we should deal with.
Down below, Olivia glanced a worried expression to Rosa.
Olivia: What are they saying?
Rosa: I-I couldn't hear.
Olivia: We should get out of here and find Basil!
Rosa: So what? Basil couldn't care about a little girl or a pretty lady anyway.
Olivia: He does care! Basil saved my life when I was nearly crushed by giant gears inside Big Ben! I know he can be self-centered and rough, but believe me, Basil is very kind and caring! Daddy and I even brought him a new violin when he sat on his old one!
Rosa looked at Olivia. Despite her adorable appearance, she was quite defending and brave, even though she didn't know her well. But if what she said was true, maybe Basil is looking for her. Maybe he does care. And Rosa's conscience was now getting the best of her. She would hate to think what would happen if harm came to the child or Basil.
The door above opened and Fidget, Russmer, and Big Tuppy climbed down the ladder. Russmer got a key out from his pocket and unlocked the cell door. Fidget grabbed Olivia and carried her away.
Olivia: Stop! Let me go! You ugly old troll!
But the bat ignored her, and he and Russmer climbed up the ladder and shut the door.
Big Tuppy: Sorry to bring you here like this, Miss Ratigan. But the boys and I think you're starting to go soft on that Sleuth Hound, Basil. We heard you knocked down Barney when he held that quack Dawson hostage. And the boss is getting concerned about you. You do remember the plan, don't you?
Rosa: Yeah. But you tell her I've got another plan.
Big Tuppy: What plan?
Rosa: A plan to…escape!
She kicked down the cell door and punched Tuppy in the face, knocking him to the floor. Then Rosa climbed up the ladder, opened the door, and climbed out.
Rosa looked around for Olivia, hoping no harm came to her yet. But she heard shouting from the dock and went to investigate. She gasped when she saw Fidget place Olivia on a small wooden board on the river.
Fidget: Let's see if you know how to swim!
He and Russmer pushed the wooden board and it drifted out onto the Thames, with Olivia, shouting for help. Thinking fast, Rosa dove into the water and swam to Olivia's rescue.
Somehow, Olivia's cries for help alerted Toby, who was nearby.
Basil: What is it, Toby? You hear something!
But Toby took off for the port. Basil, Dawson, and the Irregulars held on tight to the leash. When they got to the harbor, they spotted Fidget and Russmer on the deck.
Basil: FIDGET!
Fidget: Aaah! Not him again!
Russmer: Uh oh!
They tried to make a run for it, but Toby blocked their escape and he growled at them. Big Tuppy staggered out of the boat and on deck with the tailboard. When he saw Toby towering over him, he fainted. The Irregulars quickly tied up the villains before they could get away.
Russmer: It was Doran! He made us kidnap the little girl!
Dawson: Little girl?
Big Tuppy: Don't tell him you idiot!
Basil: Tell us what?
Suddenly, they heard Olivia's screams. Toby struck the pose of a bloodhound, pointing out to the Thames. Everyone looked out and saw Rosa swimming towards Olivia, who was still on the wooden board.
Basil: Lord Almighty! Miss Rosa!
Dawson: Oh my goodness! It's Olivia!
Even though she was far off, Basil and Dawson could see Rosa was getting tired and coming close to a faint.
Basil: If she keeps this up, she might pass out in the water and drown! (jumps into the water)
Dawson: Basil, what are you-oh, never mind. Wait for me! (jumps into the water)
Basil and Dawson swam as fast as they could to get to Rosa and Olivia. Basil seemed to be swimming fastest the most. At that time, Rosa had made it to Olivia, but was getting tired from all that swimming. She thought she was about to pass out when two arms wrapped around her. Basil had caught her just in time.
Basil: I've got you, Rosa.
He placed Rosa on the board with Olivia, and he and Dawson pushed the wooden board back to the harbor. When they got back to the dock, Olivia happily jumped into Basil's arms and smothered his cheek with kisses. Basil put Olivia down, bashful about her gratitude.
Basil: Please Miss Flapjacks, I'd rather tackle a tabby cat then put up with all this kissing.
Then he turned his attention to Rosa. She lay on the wooden boards of the dock. Basil lightly slapped her face to try and wake her.
Basil: Miss Rosa! Miss Rosa! Can you hear me?
Dawson checked for a pulse. Rosa was still alive, but she wouldn't wake up.
Dawson: We should get her back to Baker Street. (to Olivia) What were you doing out on the Thames?
Olivia: I was captured by Fidget while I was out with my daddy. They placed on that board and sent me out on the Thames.
Dawson: Don't worry, my dear. You're safe now.
Basil: Let's get you and Miss Rosa back to Baker Street, right after we take these fiends to Scotland Yard.
