John was worried. Something was off with Sherlock. Again. This time, though, was extremely different. Sherlock was cleaning and organizing his flat! John had gotten a call from Mrs. Hudson, who was equally scared, had told him what Sherlock was doing. The landlady stood in the doorway with John, watching the detective spotlessly clean his flat and organize his papers. "Do you think a demon or ghost possessed him?" Mrs. Hudson asked.
John exhaled and saw Sherlock putting his beakers in a shelf after cleaning them and diluting the unknown substances with water. "I think we should keep that in mind." he said as Sherlock moved on to cleaning the window. John couldn't handle watching this anymore. "Sherlock, is everything alright?" he finally asked. Sherlock looked over his shoulder and kept cleaning the window. "My baby sister is coming home from America." he said as he moved on to cleaning the fireplace. He took out the ashes and set them in a garbage bag. "Sister?" both the landlady and doctor questioned with dumbfounded expressions. Sherlock looked at his phone. "Guest room's done, bathroom's done, kitchen's done, and living room is done. She'll be here in a few moments." he mumbled as he finally sat down. John looked around the flat and was impressed with the work. "Since when did you have a sister?" asked Mrs. Hudson. Sherlock looked at her with annoyance. "Since sixteen years ago." he retorted as he picked up his violin. Mrs. Hudson didn't like the tone she was receiving and left for her flat. She passed by Mycroft and a young girl with a TARDIS backpack. "Dear brother, Cheshire's here." Mycroft said as Sherlock saw his sister. "Long time no see, Chess. My you've gotten big." he said smiling at her. Cheshire had the same long dark hair, but it was wavy, her eyes were a darker ice blue, and she was obviously smaller than the older Holmes brothers. "So did you, Sher." she giggled with an American accent. John came out of the restroom and saw the teen and Mycroft. "So this is your sister, Sherlock?" he asked. Both brothers nodded in response.
"Mummy and Father told me that she'll be staying in my condo."
"My, can't I decide who I want to stay with?"
"Chess, you're under our protection. Sherlock has too many enemies."
"Oh, and you have all the friends in the world."
Sherlock and John snickered at Cheshire's sarcasm. The girl did have a strong point and Mycroft gave both men a warning glare. Cheshire saw she had him pinned. "If Sherlock could survive a swan dive off a hospital, then I can survive something of that equivalency. We are Holmes after all." she concluded. Sherlock gave a winning smile at Mycroft. "You can spend days here, but dinner and where you will sleep is under my roof. I'll be back to pick you up to see Mummy and Father for dinner at four. Sherlock, they want you to come for dinner as well." Mycroft said as he left. Cheshire had a mischievous grin on her face. She sat on the couch and took out her Magnus Chase book and began to read. "John, Lestrade texted me about a murder near the London Eye. Care to join me?" Sherlock offered. John got a message from Mary and sighed. "Mary is having morning sickness again. I'm sorry." he said as he went to help his wife.
Sherlock groaned and looked at Cheshire, who had grown her little trademark smirk of her's. "Well? Let's go catch us a killer." she beamed as she dogeared her page and got up. Sherlock and Cheshire left the flat to climb into a taxi for the London Eye. There, Lestrade and other detectives were around a dead body that seemed to be gutted. Sherlock and his sister climbed out to see the detective inspector. "Go ahead." Greg sighed as Sherlock began doing his thing. Cheshire watched and thought. Like Sherlock and Mycroft having high IQ's, Cheshire was also a genius. Cheshire is like Mycroft and Sherlock into one little brain. "Obviously wasn't killed here. This is a signal that states; I'm out there. I'm here, did you miss me?" she stated. Sherlock furrowed his eyebrows and stood up. He saw what exactly she saw. "Agreed. Judging by the clothes, he had a meeting. Does he have a name?" Sherlock asked. Lestrade knelt down and searched the pockets for what was about the tenth time. "No. Must have taken it." he said finding nothing. Cheshire took some gloves and knelt down. She searched with her eyes, barely touching the corpse. "His genitals are gone, anyone else realize that? We have a Modern Day Jack." she said excitedly. Greg noticed something odd about how Cheshire was excited about a possible Ripper. "Is she….?" he questioned Sherlock quietly. Sherlock looked at Lestrade dead in the eye. "Yes, she is my sister. No, I'm not sure if she's like me that way." he blandly stated. Cheshire saw something flash in the wounds the man had. He timidly dug it out. "His name is Mark Biersack." she said holding an i.d. "Someone wants to play." Sherlock looked at her curiously and slight worry as she threw her gloves away in a portable disposal bin the police use at crime scene. Greg definitely saw something in her eyes that reminded him of someone, but couldn't place who. Sherlock and his sister were done with the crime scene and began to get down to work. "So, how is America?" he asked. Cheshire looked at Sherlock questionably. Sherlock never was into small talk. "Crazy. Politics and Hollywood are too close together. School is, in my opinion, unnecessary for real life if you want to make a career and not have tests all day. Again, my opinion." she said in an old British accent she nearly forgot she had. Sherlock chuckled and watched the buildings pass by. He paid the cabby and followed Cheshire into his flat. She pulled pull a laptop and began to work on any information on the dead man and searching anything about Jack the Ripper. She was looking for similarities between the two. The clock struck four in the evening and they both reluctantly went to the car Mycroft was in. The drive was silent as they went to the countryside where their parents gladly waited. "Hi, Mum and Father." Cheshire greeted. Both parents gave a massive hug to their smallest and youngest. "Dinner will be ready in a half hour." Mummy said as she went back to the kitchen. Cheshire went to the couch with her backpack and continued working while listening to her music.
Mycroft managed to sneak her cell phone away from her and saw the band. "Five Finger Death Punch?" he silently questioned. Curious, he went onto his smart phone and looked them up. "Burn Motherfucker Burn!" his phone began to shout. Mycroft turned YouTube off quickly before anyone heard and watched Cheshire lip sing to the lyrics. She looked at her phone and read the title of the new song playing. "The Devil in the mirror screaming that my heart is flawed, I'm never gonna let you win. No, I will not surrender, even if I start to fall, I swear to you I'll rise again." he heard her quietly sing. Sherlock stood behind Mycroft. "Her music taste has darkened. Thinking twice about sending her to America, are we?" he asked. Mycroft looked at him with warning and heard Mummy call for dinner. Mycroft went over and got Cheshire to join everyone at the table for dinner. "So, how was your trip home, Chess?" asked Father. Cheshire swallowed the large bite of ham and chased it down with some water. "It's nothing like home, dad. Music is good though." she said taking another bite of ham. Everyone was tense for some reason. Cheshire got slightly nervous about the atmosphere. "You know, I thought it was interesting to go to America. Food was good, teachers were okay, the travel was new. Getting to tour America for knowledge was interesting. I wasn't bored." she said trying to break the ice. It didn't help any. Sherlock and Mycroft were glaring at each other again. "I think my favorite was meeting Stan Lee. Also learning mythology in the New York Smithsonian." she tried again. Nothing. Cheshire gave up and went into her daydreams. Mummy knew she was trying, but it was awkward having her home after some six years abroad with Mycroft funding her. They only did that because of the work both the brothers do. Both had major and minor enemies. Mycroft didn't want to lose her if she were to be kidnapped or killed by someone he's crossed wrong. "I've decided a career path." Cheshire said poking at her potatoes. "Oh, what is it?" asked Mummy. "I'm thinking of being an author or a mythologist. I have a wide range of work choices as a creative writer, so maybe do both." she answered. Father and Cheshire began to converse with each other about schools and courses. Mycroft and Sherlock were still locked in a cold glare. "Boys, stop glaring at each other and eat for goodness sake." Mummy said as the they shot to her attention. Sherlock picked at his food as Mycroft ate his. Cheshire got seconds and ate it up before putting her plate in the sink. "I'll be in the living room." she said as she left the dining room. Sherlock followed as did Mycroft. Mummy and Father disapproved, but let them be. Cheshire was on her laptop typing away on a word document. Sherlock and Mycroft surprisingly fell asleep on the chairs near her. She took the advantage and took pictures after using a glitter pen she found in her bag. Mummy saw them and giggled at the sight. Mycroft's phone rang and he answered, unaware of the sparkly ink on his face. Cheshire chuckled when the ink got all over his Iphone. Sherlock groggily woke up and saw Mycroft's face. Both brothers looked at each other and held in their amusement until Mycroft hung up. "Really?" Sherlock said to Cheshire. She had a sly look on her face as Mycroft got ready to leave. "Come on Cheshire." he called.
Cheshire sighed and put her laptop away and winked at Sherlock. "Can we give you a ride back, brother dear?" offered Mycroft. Sherlock thought and got up to get ready to leave. "Thanks for having us, Mum." Cheshire said as they left. Mummy and Father saw them off. The ride seemed longer and Cheshire fell asleep in between her brothers during the ride. It has been a long day for her; the plane ride, the crime scene, and having awkward dinner. "I'll drop her off in at eleven tomorrow." Mycroft said as Sherlock climbed out of the cab. Cheshire was still sleeping as the pulled away from Baker Street. Mycroft woke her up when they were close to his home. They had already set her luggage in her room before meeting up with Sherlock earlier that day. Cheshire went to her room and saw a man. "Who are you?" she asked. The man was tall and towered over her as he loomed Cheshire dug into her backpack for her pocket knife. "I wouldn't go for that." another man said. He came from the bathroom connected with her room. He was smaller than his companion who aimed a Sig Sauer in Cheshire's face. "No noise. No knife. Come with me." the smaller man said. His voice had an Irish touch to it. Cheshire had no choice and followed them outside to the fire escape. She followed them into an unmarked black town car and they drove off. The gunman was driving and the smaller man sat in front of Cheshire. "My brothers can raise Hell to find me." Cheshire warned. The man cackled some and looked at her with deadly desire. Cheshire had her backpack with her and knew she had some chance if they left it with her. "You can call me Jim. This is Seb. I know your brother Sherlock quite well and know he will be devastated that you're missing. Surely it will tear Mycroft apart." Jim coldly said.
