Hi readers, this is my first Great Mouse Detective Fanfic. I've been planning on writing this story, but I decided to finish up Malina's Tale, and now I can finally start on this and my sequel to Dumbo: An Acrobat's Tale. I'm very excited to write this story. Read and enjoy!

London, 1897

On a dark and cold night in London, humans were walking through the ice-bitten air and chilly breeze blowing newspapers all over the place. Horses pulled the heavy carriages and wagons as their hooves clamped loudly on the streets of cobblestones. Big Ben echoed faintly from the distance and a dog barked. Little did the humans know that there was a society for mice called Mousedom, a place where mice, rats, lizards, and smaller animals act, dress, talk, and travel just like them.

In one particular tiny store, unseen by humans, near the drainpipe was the Flaversham's toyshop. A toymaker mouse named Hiram Flaversham owned it. He was a kindhearted mouse, who enjoyed creating toys for the children and is indeed the best toymaker in all of London, giving them joy and happiness. His only joy that made him happy was his two beautiful daughters, Genevieve and Olivia.

Genevieve was the eldest daughter and she truly loved her father and sister very much. Ever since the girls' mother died, she had to fill in her mother's role to raise Olivia, but Hiram told her that it was not necessary to do it, in order to let her relax and enjoy life from the burdening role.

Olivia was the youngest, and always loved her family. She truly loves helping others and despite her small size, she's brave deep down, and follows her sister's footsteps. Everything in the Flaversham family was peaceful and content, but that was all about to change soon.

Mr. Flaversham and Olivia were gathered around his working table tying on an apron. The youngest mouse was feeling content about her special day as she fingered a miniature rocking horse.

"You know Daddy, this is my very best birthday," Olivia said in a Scottish accent.

"Ah… but I haven't given you your present yet," Hiram said, as he too had a Scottish accent.

"What is it? What is it?"

"Now, now," he said patiently, while chuckling. "Close your eyes."

He went over to a cabinet to pull out the surprise. Olivia covered her eyes with her hands and tried to take a peak to see what it is. Then Hiram caught her.

"Uh-uh-uh-uh! Auch, no peaking now," he said. Olivia chuckled and covered her eyes again. Hiram pulled out a pink bud and placed it on the table.

"Can I see it now?"

"Not yet, we'll have to wait for your sister to come," he looked up and called, "Genevieve, are you coming? We're starting to give Olivia her presents!"

"Coming Daddy!" a voice cried, her accent had a little bit of French and Scottish.

Genevieve hurried down the stairs holding a bouquet of miniature roses. She stopped for a brief moment to smooth out her white apron that cladded with her pale blue dress outlined in white. She adjusted her necklace that hanged around her neck with a blue gem. She straightened her posture and took a deep breath as her long brown hair flowed down her back past her large ears with a white bow. She started her walk down the stairs to greet her family.

"Here I am," she said.

She came into the room to see her sister covering her eyes, and saw her father twisting a key into the pink flower bud to wind it up. Olivia opened her eyes and gasped in surprise. The bud opened to reveal a mouse ballerina wearing a golden crown, a pink gown and it danced gracefully to a sweet tune. Genevieve smiled in content, to see her sister happy.

"Oh Daddy, you made this just for me?" Olivia exclaimed happily.

Hiram smiled warmly and nodded. Genevieve came up with her present to offer to Olivia. More presents were stocked up received from their aunts, their late mother's six older sisters along with their uncles and cousins.

"Here Livi, I got these flowers for you," she said.

Olivia gently took the present from her and hugged the flower bouquet. The young mouse grinned in joy.

"Oh Ginny, this is so beautiful, thank you very much."

"You're welcome sister," she smiled. "I hope you love the gifts you got from our aunts."

Olivia decided to open her aunts' presents later, and wanted to watch her dancing doll. The doll twirled around as it stopped with a curtsy, making the girl more happy.

"You're the most wonderful father and sister in the whole world!" Olivia said.

She threw her arms around her father, and he hugged her back. Genevieve joined in as she was surrounded by love and warmth from her family, and was pulled into the hug, smiling in content.

Suddenly, there was a loud racket coming from outside, the Flaversham family looked over to see the doorknob moving frantically, as if someone was trying to break in. Genevieve felt her heart beat frantically in her chest. Hiram pulled Olivia away from the door and held her in his arms and his eldest daughter stood by his side, trembling.

"Who is that?" Olivia asked.

"Is it a burglar?" Genevieve added.

The doorknob continued to turn frantically, and the stranger started to bang on it to break it down. Genevieve felt the hairs on her fur beginning to stick up as if a nightmare was about to start.

"I don't know," Hiram quickly looked around the whole room, he noticed the cabinet, and rushed towards it carrying Olivia as Genevieve followed. He pushed both of his daughters in and shut the little door to hide them. "Quickly, dears, stay in here and don't come out! Genevieve, keep your sister safe."

Genevieve clutched onto her sister tightly to protect her, in the dark cabinet and heard the window breaking with a loud cackle of laughter. They heard grunts from outside, and Olivia walked over to take a peek at what was going on, Genevieve followed after her.

"No, Olivia, don't look!"

Olivia ignored her sister, and pushed the cabinet door slightly opened to see an ugly bat with crippled wing and peg leg, fighting with Hiram. Genevieve's heart dropped to her stomach as it began to hammer harder. Hiram struggled to fight back, as toys, tools, and paints flew all over the place. Then a table flew forward forcing the girls to fall back as the door was shut tight.

"Got ya, toy maker!" the bat said laughing evilly.

"Oh, no! Olivia! Genevieve!" Hiram called out to his daughters, but then his voice faded.

"Come on Olivia!" Genevieve cried.

The two both pushed against the cabinet door as hard as they could to get out. The table was moved, so the sisters were free. They stepped out to see the workshop all dark, cold, and ransacked with broken toys, the presents from their family members were shredded to pieces, and paint was spilled all over the place. Worse of all, Hiram and the bat were gone.

"Daddy, where are you?" Olivia called.

"Father?" Genevieve cried. "Are you here?"

Hiram did not appear, and Genevieve felt fear was pressured on her heart, as if her fears were to come true. Olivia rushed over towards the broken window and looked out among the streets.

"Daddy, where are you? Daddy! Daddy!" Olivia called out as her voice echoed in the dark night.

"Oh no, Father's really gone!" the young lady cried, and she glared at the thought of the bat. "Why that no good bat? When I get my hands on him, I'm going to wring his neck!"

She took deep breaths to calm down, and she turned to her sister as she walked over to a newspaper and tore out a page.

"What are you doing Olivia?"

"I think I know who could help us," she said, showing the paper. "The famous detective, Basil of Baker Street. He's our only hope."

"We can't leave Olivia. I promised Father and Mother I'd always protect you! Going out on the streets by ourselves is very dangerous, what if the bat came back again?"

"We can't sit here and wait Genevieve, what if something happens to Daddy? We might be too late if we don't get Basil of Baker Street."

Genevieve thought for a moment, to take in every detail her little sister was saying and knew she was right.

"Okay Olivia," she said. "Let's go get ready."

Genevieve grabbed her plain brown coat from a hanger and shrugged it on her shoulders and placed a small hat on her head. Olivia grabbed her blue coat, hat, and scarf, and they were both ready. They stepped out of the toyshop, and held each of their hands.

"Let's go find Basil."
