Note: Sooo sorry for the delay. I had a lot to do in the last days and just couldn't find the time to write... Finally, there's chapter 14. And some of you have already guessed who the intruder in the lab is... Enjoy!

Sherlock put a hand on her shoulder and Molly recognised it as an unsuccessful try at a calming gesture. She remembered his words and did not move. She knew he was scared of her jumping up and sprinting towards the lab but she was staying put, using all her will power to steady her breathing. As the voice from the main room started sounding again, Molly felt Sherlock's hand slide down her right arm slowly before moving back up. The gesture had become oddly intimate and she felt like a baby he tried to soothe.

"No, don't worry. She's not here; she's not taken off the stupid necklace for days and the signal says she's still at home. Probably watching a rerun of Friends or listening to some flippin' Beethoven or something."

This bastard. This cruel, fucking arsehole. Molly almost opened her mouth and apologised for swearing in her thoughts (as she was sure that Sherlock was aware of everything that went through her mind right now purely by staring at the back of her head). She couldn't believe it. She really had thought David was a nice guy. But - seeing as he was currently standing in her lab, talking with a conspiratorial voice to someone and making fun of her – she came to the conclusion that he probably wasn't a nice guy.

"See, that's what I thought from the beginning. Either she's really careful and way more intelligent than we thought or she's just not one of them. Hate to say I told you so…"

Molly couldn't really process what David was saying; the loud sound of rushing blood in her head overshadowed everything else. So, he had been observing her moves with some transmitter in the necklace. Why? Was he just another mad man who tried to get close to her with the intention of getting to Sherlock? Was he one of Moriarty's men? Molly felt so stupid. And angry. At David, at Sherlock. Why couldn't she be allowed some happiness for once? Why did it always have to be about him? Her anger quickly became guilt. She had done it again; she had endangered Sherlock. Molly felt sick and dizzy. As if he knew her thoughts, Sherlock tightened his grip on her arms and steadied her.

"No, at first glance it doesn't seem like there's new bodies here yet."

Oh my god! He was one of the body thieves. Or working with them. Did he know about her helping Sherlock? Was that the reason he seemed so cross when she was meeting the detective?

"Look, I better go soon. Miller and Garrett may want to come down or something. I don't want to be seen by them. Also, this Holmes person is here way too often. Sooner or later he'll catch on that something's wrong with the doctors and I don't want my work interrupted by a civilian. You really should try harder to localise Mycroft."

At his brother's name, both Sherlock and Molly gasped. He moved a bit behind her and put slight pressure on her shoulders again. She understood this as a sign not to move.

"I don't care if he's in Nicaragua, everyone at the ministry told me he's the only one who can handle his crazy brother."

At this, Sherlock stood up swiftly and quietly, and suddenly spoke. Molly cringed but didn't move.

"Oh, I regret to tell you that your information is erroneous in this point, David. Mycroft, as any other person, cannot handle me." While speaking, he quickly moved into the main room, revealing himself to a shocked David.

"What the…?"

"For a short moment, I was having doubts about my knowledge of the human nature there. I almost thought you were one of them. Of course, all is clear now. Which minister is handling this matter?" Sherlock spoke pointedly and calm. Nonetheless, Molly could hear an unusual tension in his voice.

"Health," David just said, "how long have you known and, more importantly, how much do you know?"

"We can discuss the case later on when we're not –"

"Discuss the case? Do you actually want us working together? I'm not having you interfering with this. It's a government operation and you're certainly not a trained agent. This has to be handled delicately."

"No, of course I don't want to be working with you. I merely require the information you already gathered so I can come to my conclusions quicker." Sherlock wrinkled his nose, took out his phone and dialled. "Yes, hello brother dear. How is Nicaragua? Any civil unrest? - Now, I've got an agent who apparently belongs to the minister of health and he doesn't want to play with me. Could you be so nice as to tell him there's nothing he can do to hinder me?" Not waiting for an answer, he gave the phone to the other man who reluctantly took it.

"Hello sir. Yes sir. Yes, that's… No, of course but… Yes, he does, apparently. But… Yes, good." With a grim face, David handed the phone back to Sherlock.

"So? – Very good. I'll have to invite you to a nice Weight Watchers dinner as a thank you when you come back from your trip. Enjoy the sun and the drug murders while you're down there."

"So, what now? Should I fill you in on the details, sir?" David asked with a sour face, sarcasm dripping from his words.

"Later. Why have you been using Molly? There are so many other ways to get into the hospital." Sherlock's voice was definitely not calm anymore, now. His tone was menacing.

David was surprised by this turn of the conversation. After a pause, he answered, "it was convenient, with my sister knowing her and all. That's basically why they flew me in from Australia. And, after all, she is very naïve and gullible. Oh, what am I telling you – I've done my research; you know very well to manipulate people for your means. And, we couldn't be sure that she had nothing to do with it," he added half-heartedly. "Like this, I could also monitor her. Killing two birds with one stone, you see." Now, he sounded almost cheery, seemingly thinking Sherlock would understand his reasoning and agree.

"I see," Sherlock brought out through gritted teeth, "and the fact that my brother trusted her enough to let her work with me wasn't satisfying for you lot? Don't make up reasons. She was just an easy way in. You really toy with people like they were puppets. You disgust me. What if they would have found out about you? You endangered her."

"Man, don't be so serious. Nothing happened, nobody got hurt."

"Nobody got hurt? How do you think Molly will feel about this? You fooling her like that. Making her think you care. Making her care for you…"

"Now, come on. No reason to get all teary." David said, "but, you know you're right. It would be a pity if she knew why I started dating her. I don't suppose you could keep that bit to yourself until all of this is over?" Sherlock just stared.

"Ah well, thought so. Bummer. She has quite the nice arse. I'm sure you've noticed yourself. And she really goes like the clappers, if you know what I mean." David, by this time could see that Sherlock was furious and the detective knew that the other man was saying all this on purpose. The blonde man put on a dirty smile before speaking the next sentence.

"And you wouldn't believe the things she does with her –" David never got the chance to finish the sentence, for Sherlock's fist was making contact with his nose that very same moment.

Not having expected the hard blow, David raised a hand to his face and tried to stop the immense amount of blood coming from his nostrils. With the other hand he grabbed a desk to keep his bent posture from falling down. With an unbelieving expression he looked up at Sherlock whose eyes sparkled violently when they met his.

"You know what's funny?" Sherlock asked without the slightest hint of amusement in his voice. "I've literally dreamed about doing this. Come on Molly, we're leaving," he added a bit louder.

David's face went even paler than it already was. Very slowly, Molly stood up and walked into the main room of the lab. Her face was red and she gravely stared at Sherlock for several seconds. Then she turned and looked at the still hunched blonde man. Sherlock had never seen such a despiteful look on her face. But, oddly, she also looked grand and proud. She didn't say anything and locked eyes with Sherlock again before nodding almost imperceptibly.
