Hey! This is my first fanfiction! ^^ I'm really new to this so excuse me if something is wrong and please be nice to me. And I don't own any of the cat returns characters or the great mouse detective characters.

Edit: Credit goes to Sindy Sugar, since after reading her story Return of the great Cat and Mouse I got inspiration to write my own :D

Chapter 1

"Haru, are you listening to me?" Haru turned her head towards the sound.

"Yes? What were you saying?" Said Haru and smiled at her friend.

Hiromi shook her head stated and sighed. Lately Haru had been in her own world all the time. It felt like she was thinking about something that wasn't good for her.

"I was saying that isn't it nice here?" Hiromi said bit annoyed. She started to get tired of always repeating herself for Haru, and lately she had done that a lot. Even when they had summer vacation it didn't seem like Haru didn't enjoy it at all.

"Of course, but I think that it's better back home." Haru said and looked and the menu for the café. "Maybe I will have some chocolate cake?" She said while Hiromi sighed but thought that at least they had fun together. "I should have taken a jacket with me." Hiromi mumbled and started to feel the cold summer wind in her back. "Next time maybe you would think twice before taking on a summer dress before going out then." Haru teased her and felt happy that she was wearing a light blue sweater and some black jeans, instead of wearing something cold like a summer dress like Hiromi.

Right now they were both spending their summer in London together. It hadn't been easy persuading her mother to let her travel alone with Hiromi, but she had made it. After her little adventure she had found a job and saved enough money so she could travel. And now they were sitting outside a small café and talking together while enjoying the hot summer weather, or at least Hiromi enjoyed it.

Lately all Haru could think of was her time in the cat kingdom together with Baron, Muta and Toro. It really had been a wonderful time for her. But she really missed them and wished she could see them again. But the times she had tried to meet Muta again and make him take her back to the bureau, she hadn't seen him at all. And it felt like she still had a crush on the baron since she confessed her feelings to him. The thought of that made it even worse to not be able to see her friends again.

It had been several months, but it really felt like everything happened yesterday. And Haru hadn't changed much since then either. Her brown hair had been shorter but had grown longer since then, but she still hadn't grown very much since then as a woman. But it didn't really bother her so much since she wasn't really interested in the boys at her school.

She really wanted to go back to the time and have an adventure again with everyone. But right now it had been several months since she had seen them, and started to think that she never would either. And sometimes she wished that she could have an adventure again. "I guess I shouldn't wish for that." She thought and smiled to herself.

Meanwhile….

Somewhere in London while Haru was eating some cake with Hiromi, a small mouse where running for her life while holding onto something very important in her small hands.

She could hear footsteps behind her that was following her and tried to get what she tried to protect. And she knew for sure that if she gave them the thing she had in her hands it would be horrible.

Before she knew it she had run in an alley and right in a wall. "No!" She said frustrated and punched the wall angrily.

She could hear that the ones following her were close. And before she knew it a white mouse appeared behind her and walking towards her slowly. The white mouse was wearing a black cloak that was hiding his face, but she could still see his white fur.

"You have nowhere else to run now, so please won't you give it to me?" The white mouse said with a deep voice, and stretched out his hand to take what she had from her hands. "If you want to take it you have to do it over my dead body!" She hissed to him angrily and pressed what she had tightly into her body.

He sighed and shrugged with his shoulders while giving her an arrogant smile. "Then…I guess we have to do this the hard way." And while he said that more white mice appeared behind him holding swords in their hands.

The girl stepped a bit back and could feel the wall against her body. If she didn't think of something quickly they would kill her for sure. As long they got what they wanted they didn't need her at all.

She quickly found a colorful ball inside her pocket and threw it to the ground. And when it hit the ground smoke started to come out of it and surrounded all of them.

"Don't let her get away!" The leader screamed and tried to see behind all the smoke. "There!" He whispered and threw a knife towards the running mouse.

"Aaaahhh." She moaned in pain and felt the knife in her back. But she continued to run and didn't care about the pain and the blood that was started to drain from her back.

Back to the café

Haru looked at her clock and literally threw the rest of the cake in her mouth. "It's starting to get late, maybe we should get back to the hotel?" She said with her whole mouth full of cake.

Hiromi who was texting her boyfriend looked up from the phone. "I guess we could." She said and saw that the sun had started to go down. "Or maybe we should go and find some fun." She grinned and looked playfully at Haru.

"What are you talking about you idiot?" Haru sighed and didn't even want to think about what her friend meant by that. "I thought you had a boyfriend."

Hiromi tried to play serious but started to laugh. "Don't worry, I'm only joking you know." She said and got up from the chair. "I hope you know the way to the hotel then, because I don't remember it one bit."

"Let's hope we get back then before it gets dark, who knows what could happen to us." Haru got up quickly too and started to walk in the direction she was most sure was the right way back. Hiromi hurried and walked right beside her.

"So you don't see any British boys you like here?" Hiromi said playfully to Haru. "What? No!" Right now she couldn't think of looking at other boys. She started to think of the Baron and blushed. "I have told you I like someone else, so I don't think I need to look at anyone else." She said and felt that her whole face had turned red.

"But you won't tell me who it is." Hiromi said and pouted while walking. And of course Haru had no intention to tell her. Even if she told her she was sure that her best friend would think she had turned crazy or something.

Meanwhile…

While Haru and Hiromi was walking back to their hotel, the little mouse girl had collapsed near some buildings. "It hurts…." She held her hands tightly in chest. "What should I do?" She thought to herself and closed her eyes.

In her hands was a necklace formed like a key, with a watch on the end of the key. This thing she had tried to protect with her life, and almost had failed to do so. "I can't do it anymore." She whispered in pain, had to do something with it quickly before someone found her.

The humans was walking past her, not noticing a small wounded mouse lying on the street. She whispered softly to the key formed necklace, and slowly it started to disappear from her hands. A small smile came to her face.

"Mom, what's that?" A small boy asked and pointed towards a small glowing light. "What?" His mom asked and looked. "I can't see anything over there." She pulled her boy with her quickly. "Hurry now." The boy looked back one last time. "I'm sure I saw something." He mumbled, wondering what he just had seen. Back where a dead mouse once had been, it was now nothing there at all, expect some trail of blood.
