As the summary says this is about John coming home with a youngster. Disclaimer: I don't own Sherlock Holmes in any which way shape of form. Um…Hope you like it

Sherlock Holmes plopped another finger onto a small tray and injected it full of some substance that was unknown to the normal person but Sherlock wasn't a normal person and his partner in both crime and the bedroom was out listening to a will that was written by an old girlfriend he had about six years ago.

That was seven hours and he should be home very soon as long as he left right after. But that didn't matter right now because he was seeing how long it would take for flesh to deteriorate from the poison he injected into them.

John Watson sighed clenching and unclenching his hands and glanced over at the sleeping child that sat next to him in the cab. He couldn't believe what just happened. He went to the lawyers' office feeling extremely uncomfortable because he was the only person not crying. Then he heard something he thought he would never hear, he heard he would be taking home the same child that was sleeping next to him because apparently they had a child together and John left before she knew she was pregnant.

They arrived at 221 B Baker Street after the long ride and John was about to wake up the boy but decided against it and leaned across the seat and unbuckled him. He paid the cabbie and picked up the small boy's bag and then the slid the child over and lifted him out of the cab. He walked into the familiar hallway and paused. 'What about Sherlock?' He asked himself worry over what the sociopath would say to him just walking in with a child in his arms. He would never want to have a kid around. The way they get in the way, how they always talk which could be very bad around Sherlock when he's in one of his moods.

"John can you grab me my phone?" Sherlock yelled from upstairs knowing John was home.

John was about to yell back but the kid in his arms started to squirm. "Are we there yet?" He asked lifting his head from John's shoulder.

"Yeah," John answered quietly climbing the stairs. He was about to open the door when it was opened for him.

"What's taking you so long J-. " Sherlock stopped himself when he saw the boy in John's arms. "What did you do?"

"Come on it's not like you already haven't deduced it yet," John stated.

Sherlock nodded knowing full well what happened. "You had a child with her but didn't know about him and when she died she named you legal guardian and now here he is," Sherlock looked the boy up and down.

"I'm sorry Sherlock but I can't just leave him. I can get Mrs. Hudson to watch him when I go to work and also when we go to work on a case so he won't bother you," John said quickly putting the child down.

"Very well," Sherlock said still not looking away from the child.

John nodded and was ready to turn around to leave and talk with their landlord. "No experiments," He ran down the stairs.

Sherlock knelt down in front of the boy scaring him a little. "What's your name boy?" Sherlock asked sharply.

The small child hesitated but then answered with confidence and said, "Lucian Watson."

"Age?" Sherlock demanded.

"Five almost six." Lucian said proudly. "What's your name?"

"Sherlock Holmes," Sherlock answered swiftly. "Do you know John is your father?"

Lucian nodded smiling but it soon dropped. "Mummy said I would go to him when she died," he stated trying not to cry…again. "She said he is nice." Sherlock nodded and stood full height and stalked into the kitchen to his fingers.

John came back into the room noticing Sherlock was no longer near Lucian. "So Lucian what do you want to do?"

Lucian looked around. "Do you have a telly?"

John's face fell. They just lost their television when Sherlock got bored and started shooting holes into the wall again and missed. "Not at the moment no," John frowned when he saw Lucian's face fall and started crying. He got down on his knees and pulled him into a hug. "Shh, don't cry we can do something else beside watch the telly. How about I read you a book?" John asked hoping he would agree and to his relief he did. Then he remembered they didn't have any kid books. He lifted Lucian up and placed him on the couch. He started searching for a suitable book.

John was unaware of Sherlock's gaze following his every move. He walked in from the kitchen and over to the book shelf. He plucked a book out with ease and handed it to John with a small smile. "Try this one."

John looked at the title, The Adventures of the Crew; it was one of his of course. He shrugged his shoulders he figured it would be the closest book they had that would be interesting to a five year old. He sat himself next to Lucian on the couch. "Alright let's begin shall we."

After an hour of reading Lucian fell asleep curled up into John's side hugging his jumper. "Hey Sherlock?"

"Yes John?" Sherlock asked sipping his coffee.

"Are you alright with him being here?" John asked. Sherlock lifted his eyes from the paper he was reading and looked at john. John's palms got really sweaty and he tried wiping them off in his pants. "I mean if you're not I'll move out."

It was Sherlock's turn to get nervous. He didn't want John to leave even if he didn't want to have a kid running around. "I'm fine with it John as long as he doesn't disturb me while I'm working."

"Are you sure?" John asked not believing him.

Sherlock stood from his seat and glided over to John sat next to him and slid his arm over his shoulders. "I'll deal," Sherlock assured him. "The others will be surprise to hear about it." Sherlock took and glance at Lucian.

"Him Sherlock not it," John corrected him.

Sherlock rolled his eyes and jumped up. "I have to go tell Lestrade who killed Mr. Hoth. Don't wait up," He yelled while walking down the stairs. John sighed and carried Lucian up to Sherlock and his room sp he could sleep better.

Sherlock climbed into the cab and gave off the address for Scotland Yard. When he got there he walked right past Donavan ignoring the 'hey freak' she gave him and into Lestrade's office. "It wasn't the blow to the head that killed him it was the poison that was injected through his fingers that did it."

Lestrade looked up from the file on the case that Sherlock was talking about. "How do you know that?" He asked.

Sherlock shook his head. "Think! Why would someone bash somebody's head in then inject them with a deadly poison after they were dead? No it makes more sense the other way around plus it gives us an answer to who killed him."

Lestrade tilted his head to the side and crossed his arms. "Who did it then?"

"His sister!" Sherlock stated. He was watching as Lestrade still didn't get it. 'Idiot' he thought. "He and his sister never got along. Plus their mother was sick and in her will it say who ever the oldest is gets all of her money. Mr. Hoth being the oldest he was going to very rich very soon. The sister got jealous so she decided to kill him. She is a doctor so she has an unlimited supply of drugs, which at the wrong amounts could kill anyone, available. She stole some from her office and brought it over to her brother's house and killed him in his sleep. She thought it all out she would inject him then bash his head in to throw us off," Sherlock waited for a reaction, upon getting none he continued. "If you check underneath the bathroom sink you'll find the drug, she may be a doctor but she isn't smart enough to depose the drugs.

"How do you know the drugs are under the sink?" Lestrade asked.

Sherlock looked at him then answered, "The way she walked."

Lestrade nodded like he should have known that. "When did you find this out?"

"This morning," Sherlock stated. "I needed to do some things before I came here to make sure the fingers would have fallen apart before the blow to the head was given."

"Alright," Lestrade said having enough information to go on and raced out of the room.

Sherlock followed but slower knowing where he was going now. He was going shopping for the child that was now living with John and him. He was doing this because it would be a distraction later on when things were happening and he couldn't have that, he wasn't doing this for Lucian at all.

John glanced at the clock, Sherlock left at seven and now it was ten. 'Where the heck did he go?' he asked himself. 'It can't three hours to tell Lestrade that it was his sister who did it, could it?' John heard the explanation this morning when Sherlock burst into the bedroom shouting how stupid they were for not noticing it. John suddenly realized he was very tire and curled up on the couch and went to sleep not bothering to change.

Sherlock walked into the living room of their flat and placed the bags that had some clothes and toys he figured would keep the boy busy and not constantly in their way. He noted John asleep on the couch which meant Lucian was asleep in their room. He walked pasted John placing a blanket over his shoulders and into the kitchen.

John cleaned up earlier and moved his fingers to a counter and not on the table probably to eat something without severed limbs in his face. Sherlock smiled and shook his head and walked back out to the living room and sat in his chair, grabbing John's laptop and easily getting past his password protection.
