A/N: First thing first; I have to say I feel so happy for the seven Emmys "Sherlock" received this year. I believe that we all agree that Benedict's acting especially in his "last vow" is impeccable. I do hope that the BAFTAs saw this award and soon a BAFTA will follow for Benedict as Sherlock.

Secondly, now that we have an air year (2016) I think you'll see more of me, because 2016 is not that far and we all know how evil the Mofftiss can be. More Sherlolly is necessary in order to endure the waiting.

Enjoy the chapter!

DISCLAIMER: I do not own Sherlock Holmes. He belongs to Sir Conan Arthur Doyle. Molly Hooper belongs to the creators of Sherlock in BBC. I only own the plot.

The Key

It took Sherlock five minutes of exile in order to come back.

In these five minutes he had lost and gained everything and everyone back.

As soon as the airplane landed Sherlock headed to John who was waiting for him outside the car. With steady steps Sherlock approached him and embraced him. That was the first time that Sherlock was hugging John.

Sure John had hugged Sherlock after his best man speech in his wedding but that was different.

Sherlock in five minutes had lost and gain back the brother he had chosen to have, the friends he considered family; Lestrade, Mrs. Hudson and Molly. He could see them again. He could live with them.

However, Sherlock knew that he had also to save them again. If Moriarty was back he had to save them again.

" Sherlock Moriarty is b…"

"is back. I know John. Mycroft informed me. This is way I never left. " Sherlock said calmly but his mind wasn't so calm.

He was trying to think what he had missed. He was trying to think if he hadn't count a detail in his plan. However, he remembered crystal clear the sound from Moriarty's gun. He saw him lying dead in a pool of blood in Saint Bart's rooftop...

What had he missed?

"Sherlock? Sherlock? Do you hear me? What we do next?" John asked him waiting for instructions.

"We go to my brother. He is the one who is going to give us every detail about "Moriarty's" video. But first, you go home. Leave your wife there and I go to Saint Bart's to find Molly "

John understood the worry in Sherlock's voice so he tried to calm him down;

"Sherlock listen to me. Molly is safe. The only people who know about their involvement in your faked death is me, Marry, Mrs. Hudson, Lestrade and Aderson. We are your friends. We are Molly's friends and we do not want any harm to come to her. Nobody else knows anything about her involvement in your "death" ".

"No John. The British government and the judges know that too. If whoever made that video has that information Molly clearly is in danger. Moriarty once said that he is going to burn the heart out of me. I planned my demise so you, Lestrade and would be alive. I won't take my chances now. I won't let whoever is involved with this video to burn the heart out of me. I won't let them touch a wisp from my pathologist hair! " Sherlock relied with sincerity.

John was standing bewildered. Did just Sherlock Holmes had called Molly Hooper his heart or he simply was saying that he was so important to him like they were?

John had no time to think. He followed Sherlock inside the car where he was explaining to Mary his plan.

"Mary you go home. I won't negotiate that. Actually, you 0both are going home and I'll come later to collect john. In the unlikely event that anything happens I know you can defend yourselves. The three of us know how skilled you both are with weapons…However I presume Mycroft would already have under surveillance your neighborhood. As soon as I leave the hospital I'll call you John to get ready."

They ride to Saint Bart's in silence. Both John and Marry knew that Sherlock needed the time to go through things relevant to Moriarty.

The Watsons left Sherlock on the back door of the hospital near to the morgue and headed to their house.

As soon as Sherlock stepped into the hospital his heart rate elevated. His mind started thinking faster than before. If Moriarty or anyone else related to him was behind from that video and anyhow they had obtained the crucial information regarding Molly, she would be the first target. She would be the first target because she was the one who made everything possible. Once Moriarty had told him that in a world with lockers the man with the right key is the king and definitely Molly Hooper is Sherlock's Key, not only because she helped him stage his death but for everything she had done for him.

Sherlock started eliminating possible places where Molly would be right now if she had seen the video. Certainly she wouldn't be in the morgue. Not even in woman's locker room. The men's locker or the canteen were two good places to be. He had decided to start from the men's locker and if she wasn't there she should be in the canteen. He walked outside the morgue and turned in the left for the lockers. As soon as he turned, it dawned to him something.

If he and Moriarty were the same they will be thinking alike. This meant that if Moriarty was indeed behind this video he would be heading in the same places like Sherlock.

However, hiding in the least expected place was the safest thing to do and he knew that Molly Hooper was a woman of many surprises. Sherlock turned back and walked towards the morgue. He knew that Molly would be there. He wished she would be there.

He entered the morgue and saw a dim light coming from her office.

Sherlock took few steps towards Molly's office but someone hit him on the back with something he couldn't identify. Sherlock fell in the floor. He was lying on the floor with his hands locked above his head and a person above him.

He smiled widely;

"You are safe. Molly you are safe "

"Indeed I am. I didn't know it was you that came in…if I knew I wouldn't have hit you…but your brother told me that he would come for me in an hour or so.." Molly explained to him without setting his hands free, without letting him stand up.

" Plans changed " Sherlock said apologetically to her knowing what is coming next so he tried to prolong even more the fact that he had to give her an explanation why he never told her in person that he was leaving the country before the whole Moriarty thing.

"I figured...but you have to give me some credit as least I know how to protect myself" Molly giggled trying to hide any indication of pain in her voice.

"Defend yourself? Come on Molly! We know that our present positions can easily change. I can turn you upside down so I have you beneath me"

"You underestimate me again Sherlock. Do not forget that I am a trained doctor. I work with various surgical tools every day and that I am particularly fond of the scalpels. So if instead of you Moriarty had walked in here, stay assured that he would be lying dead in the floor, encircled by a pool of his own blood with his carotid reaped" Molly said with such determination that Sherlock knew that she could do that if necessary.

Yet again Sherlock Holmes had underestimated Molly Hooper. However, not because he doubt her abilities or her loyalty to him, no. He doubted her because Sherlock was afraid that he might lose her. He was afraid that he wouldn't be able to keep her safe and sound.

He was so deep into his thoughts that he didn't even realize that they were still lying on the floor with Molly above him.

"Emm…Sherlock do you carry a weapon with you?" shyly she asked.

"No why?" Sherlock hadn't yet realized why she was asking him such a question.

Hearing his answer Molly blushed instantly. In her try to make him realize why she was asking she looked Sherlock in the eye blushing even more. It took Sherlock only a minute to understand that the reason why Molly was asking if he carried a gun with him must be his aroused manhood.

"Not that kind of a gun... I think the idea of Moriarty lying dead in your floor with his carotid reaped by your own hand must have made me extremely happy" he teased her.

"You git!" Molly told him and then she bent her head and placed a soft kiss upon his lips.

"Oh! By the way, do not think that you are off the hook with the whole "I am going to an exile" thing mister! You never said a word in person and you expected me to carry on my life like that? Promise me this is the first and the last time that you go anywhere for so long period of time without telling me anything. Because you can tell me anything... you know that."

Sherlock didn't answer.

Well he didn't answer with words; instead he grabbed her blouse and snogged her.

After that kiss or various kisses after that they both stand up.

"Time to go Molly. I need to make sure you will be safe and sound during all this mess. We have to see what my dear brother has planned for your protection." Sherlock informed her.

"Sherlock I will be ok. You should look after Mrs. Hudson and John. I am sure Greg can take care of himself…not that John cannot but we all know that he is more prone to..Well…unlikely events... " Molly commented.

Once again Sherlock was amazed by the woman in front of him;

"Molly Hooper, you are a wonderful woman; a wonderful human being. You always think everyone else, their safety and well-being before yours. You even think first the undeserving like me…"

Molly didn't let him to finish his sentence " Sherlock Holmes one more time to hear that you are undeserving and I'll slap you again. Sure you are an arse from time to time but you are an arse we love, the arse I love so do not think like that again..please..."

He nodded affirmatively even when he knew that Molly Hooper deserved better than him.

"My point is that I need to be sure that you'll be safe Molly. Of course I know that you can defend yourself but I need to be sure that you'll have extra protection measures so I can work more quickly in order to solve "Moriarty's" riddle. Just so you know Mrs. Hudson is safe and John has his wife if he needs extra protection." Sherlock said to Molly without thinking what he had said.

"It was Mary, wasn't she? The one who shot you... That's why you kept repeating her name when they brought you in and sometime after your surgery" she said not really waiting for an answer.

Sherlock nodded again and was about to speak but Molly cut him off;

"I do not want you to explain me anything. You can tell me whatever you want when you want, IF you want. "

Sherlock had no word to tell so he acted; he hugged Molly not letting her go and kissed her with all the strength he had in his body.

"We will have time to talk about everything, but now we have to go. We have to collect John and go see the British government" Sherlock commented.

" You mean we have to see Mycroft…" Molly corrected him smiling.

"Yeap! Just give me your phone so I can call him. Mine is in his office confiscated because I am a sentenced murderer….and I'll understand if you don't wish to continue our relationship because of that" Sherlock said with worry and a bit of hesitation in his voice.

This time Molly hit him in the head with a light file from the near desk;

"Listen to me Sherlock Holmes and listen to me carefully; you may doubt yourself and your actions but I do not even know why you killed whoever you killed so I cannot judge you without knowing. So when the whole "Moriarty; the sequel " is finished you can talk to me about that so I can decide myself if you are a murderer or not. Also, let me tell you that I want you to speak to me before you act. I need to know beforehand if I have to help you escape your death again. Not that I want to do this ever again, because this means that we have to lose you yet again and I know that none of us can go through this pain again..."

Some tears made their appearance in Molly's eyes and Sherlock wiped them away.

Sherlock said nothing more. He had nothing else to say. It took him so many time to realize that he belonged with Molly and when he did she was engaged to be married another man. Then she was single again and he was shot and killed a man after that.

Nevertheless, Sherlock now was back. Back to everyone he loved and cared about. He promised himself that now he would think more before act because there was one more happiness that he cared about in this world beside John's; it was Molly's happiness.

Everything would be alright. He was home, he had his friends and among them there was the one who could trust again for the lives all of them. The one who could trust with his life. Sherlock had Molly Hooper.

Indeed, in a world full of locks Sherlock Holmes had the most valuable Key he could ask for.
