Sherlock meets the Avengers- A crossing of fandoms

You have GOT to be kidding me

It had been a week since the 'drugs' incident. Sherlocks arm was almost healed and the tower had been quiet. Mostly. Sherlock had barely convinced them he wasn't an addict, which was true. He was a user. He could quit any time he liked, just like with cigarettes. But it helped to quiet his constantly moving and changing mind. Helped him think clearly without haveing some huge revelation about a case from three years ago. But, he knew he had to stop. He needed something to occupy himself, otherwise he would need to fix the bordom with something less than legal. He would never kill someone, not unless it was self defence or they realy deserved it. Like the man with information on every important person in the world. Like Moriarty. But, wile sherlock continued to think like this, the world was in need. Things were happening. And he was about to be a big part of it again. Sherlock had been thinking in his room for an hour now, not mind palace, just thought. But, it was cut off when his phone rang and he had to pick it up.
"Hello?" Sherlock asked, raising an eyebrow. The only people that would call him are in the building. He didn't recognize the number.
"Hello sherlock. Do you... remember this? Here's a hint. Boom." The voice said, it was a man, they were crying.
"Again? Are you serious? More boom wrapped stolen voices?" Sherlock asked, shocked. He remembered this from the first time Moriarty started makeing trouble. He would wrap people in bombs and make them say what he wanted. He would give sherlock a serton amount of time before the victim would blow. In that time sherlock would have to solve a case. If he solved it, the victim could tell him where they were and live.
"I am assuming that you remember this works. No tracking the call. Just solve the case I send you and you get to save the damsel in distress. Sorry this one's a man." The man said, reading with a very shaky voice. Sherlock had walked out into the living room and put the phone on speaker, putting a finger to his lips to keep the others quiet. They needed to hear it. They needed to know what was happening.
"Why? Moriarty, we don't need more deaths. What is the point of risking inoccent lives? We already know who you are. Just use your own voice." Sherlock stated calmly.
"I like to watch you dance, sherlock. Like to make you play the game. You have 24 hours for this one. You remember what happens if you fail. I will remind you of the rules. The victim is only saved if you solve the case. What do you say I give you back that phone from 'the study in pink'? There will be one number on there. Call with the answer." The man's voice spoke through the phone, still crying. The call then ended, leaving sherlock with a case to solve, and a life to save.
"What the hell was that!? Sounded like some poor guy reading something." Tony exclaimed, confused. Sherlock frowned.
"That, that was Moriarty hitting the reset button, going back to the begining. The first time John and I ever delt with him, he was wrapping people in bombs, like the one you saw John in at the pool warehouse. They were texted what they were supposed to read and they called a number they were given. A number I was connected to. I was given a limited amount of time to solve the case. If I didn't do it, the victim blew up. They can't leave the place they are standing or they blow. They can't say anything but what they are told or they blow. Moriarty is doing it again. And we can't track the number. If we do, the victim blows up. The only way to save them in is I solve the case before the time is up. It's not even related to the victim. Just a random odd job to make me 'dance'. We have to play the game." Sherlock explained, totaly somber. He had to save a life. Even if he had done this before, he was used to solving murders, not saveing lives.
"Are you kidding!? This guy is sick! What are we supposed to do here!?" Tony exclaimed, furious.
"Sir, there is a man in the elevator, says he has a phone to deliver to Mr Holmes." Jarvis stated blankly.
"We solve the case." Sherlock stated, walking to the elevator and signing for the phone as the door opened before takeing the device and sending the man down.
"We can't just go along with this!"Tony yelped. Everyone else had their heads down.
"We have to! Would you rather have the civilian die!? I don't like this any more than you do. The last time I played this man's game I ended up faking my own death! But I am going to save this life. Moriarty has us cornered. We either play his game, or people die. This is not something you can 'Tony Stark' your way out of! We have to do this his way." Sherlock barked, ending in an almost growl. Tony stared wide eyed at the detective.
"When did people start scaring me in my own tower?" Tony asked, worried.
"The day someone smarter than you had to show you how to play the game and not jump the gun. Strategy is going to save lives this time." Sherlock stated, opening up the phone and looking at the text, it was of sherlocks room. He paled. Sent five muinets ago. The clock in the picture read half an hour ago. The people were long gone.
"What is it?" Steve asked, the second person to pipe up.
"The clue will be in my room. The person that left it is long gone."
"What!? How did someone get in my tower!?" Tony yelled.
"Moriarty has a god, Tony.  Most likely Telaported in, took the picture, left the clue, and left."
"I am so done with everything right now."
"Everyone is. come on." Sherlock stated before running down the hallway to his room, stopping in his tracks at what he saw.
