Sorry to all those hoping for a Sherlock update. But this happened! Basically it's a rewrite of Into Darkness with Edith instead of Kirk. However, I do plan on adding some originality into the mix, but it might be a while coming!

I'm going to say that it's set between the point in the 2009 movie where the USS Kelvin was attacked and the main body of that film.

Also, Edith was not present at the conference where Khan attacks the high ranks of Starfleet and Scotty was dismissed by Admiral Marcus, not by Edith.

I do not own Downton Abbey or Star Trek into Darkness or the characters involved or anything else. Although if Benedict and Laura do ever embark on a relationship, I might try and claim that I wrote it first!

Unbeta'd.

Enjoy. :)

Edith stared at him through the glass. She'd taken Spock's advice and taken the man prisoner as opposed to killing him outright. She'd saved him, just as he'd saved her in the fight with the Klingons. The moment she first lost herself in his clear grey eyes; her gun gone and a ferocious Klingon looming over her. Once everything was under control she just had to slap him; to touch him; to feel those cheekbones under her palm. She had to admit it to herself – she'd have kissed him if she wasn't the captain leading a landing party on a mission. Just watching the power he possessed and the way he handled his weapons was enough to make her legs turn to jelly. And then he had the nerve to ask her if he could have a shower once they got back to the Enterprise. The images! And she knew she wasn't the only one affected by him. The new blond science officer had eyed him up quite obviously as they made their way through the ship.

Standing, facing him now though, she could tell he was dangerous. It was as if he was trying to warn her, save her again maybe. What had Spock said? "He will only try and manipulate you." She'd wanted to laugh at that, but there was no way she would be telling the first officer that the tight, black uniform that the prisoner was wearing was already manipulating her enough. She'd asked him to give her a minute, which is why she was now standing back where she had been, only this time it was just her. And him.

"Clearly you're doing this against your orders, so tell me, why did you allow me to live?" A shiver went down her spine at the sound of his voice.

"Starfleet do not condemn people to death without a trial." She tried to sound professional.

"No. You have a conscience, Miss Crawley. You do not condemn people to death without a trial. You alone. Starfleet have no such morals." He saw the scepticism in her eyes. "Let me convince you of the truth." He paused. "23-17-46-11. Coordinates not far from Earth. If you want to know why I did what I did, go and take a look."

"Give me one reason why I should listen to you."

"Because you need me. You have no idea what you are up against. I am not the real enemy here, but I can help you defeat him. Providing that you promise not to use the torpedoes."

Edith had to force herself to tear her eyes away from his. He was so intoxicating. "The torpedoes?" She stated cautiously.

"I suggest you open one up."

She breathed in deeply, looking him directly in the eyes. His own gaze was steady. Could she trust him? Spock was right. He was manipulating her, and on the basis of a gut feeling, she was prepared to be manipulated. She nodded slowly then turned on her heel and walked away. However, her confident walk faltered once she was out of his sight. She shut her eyes and leaned heavily against the wall. "This is a dangerous game you're playing, Edith Crawley." She muttered to herself, before calling Scotty. Between the drunken flirting, she managed to give him the coordinates Harrison had given her and just had to hope that Scotty would go find whatever it was. She then made her way to the bridge.

"Are you out of your mind? You're not actually going to listen to this guy?" The initial reaction of her senior medical officer was worse than she'd hoped at the suggestion of opening a torpedo. "He killed a number of Starfleet officers, and now you think it's a good idea to pop open a torpedo because he dared you to."

"Why did he save our lives, Bones?" Damn it! She was defending him.

"The doctor does have a point, Captain." Spock added.

"Don't agree with me, Spock. It makes me very uncomfortable." McCoy retorted.

"Perhaps you too should learn to govern your emotions, Doctor. In this situation logic dictates…" Edith ran a hand over her face, despairing at their argument.

"Logic? Oh my god! There's a maniac trying to make us blow up our own damn ship and…"

"That's not it." She finally interrupted. "I don't know why he surrendered, but that's not it."

"You trust him already, do you not?" Spock asked her. She had to ignore that.

"Look, we're gonna open a torpedo. The question is how."

"But Edith, without Mr Scott on board, who exactly is qualified to just pop open a four-ton stick of dynamite?"

"The Admiral's daughter appeared to have interest in the torpedoes, and she is a weapons specialist. Perhaps she could be of some use." Spock offered.

"What Admiral's daughter?" Bones asked.

"Carol Marcus. The new science officer concealed her identity to board the ship."

"The blond one?" Edith had to affirm.

"Yes."

"That Doctor McCoy was chatting up on the connecting flight between Earth and the Enterprise?"

"Me?"

"Spock and I both said we don't need another science officer. And what did you say? The more the merrier." Bones looked at Edith with a slightly wounded expression gracing his features. Edith rolled her eyes. "I'll go and talk to her." Edith left the bridge to find the blond woman.

~X~

"I need to talk to you about torpedoes, Doctor Marcus." Carol paled at Edith's tone.

"Yes Captain. Are the torpedoes still in the weapons bay?"

"Loaded and ready to fire. What are they?"

"I don't know. That's why I forged my transfer onto your ship to find out why. I do apologise for that. By the way, if I caused you any problems, I am sorry."

Edith shrugged. "Let's just deal with the torpedoes." They walked quickly towards the weapons bay.

"My father gave me access to every programme he oversaw. Then I heard he was developing these prototype torpedoes. When I went to confront him about it, he wouldn't even see me. That's when I discovered the torpedoes had disappeared from all official records."

"And then he gave them to me." Edith added, resigned. They got a couple of men to unload one of the torpedoes.

"It's too dangerous to try and open one of these torpedoes on the Enterprise, but there is a nearby planetoid. I can open one up there, but I will need some help."

~X~

"Mr Sulu, have Doctors Marcus and McCoy landed on the planetoid yet?" Edith asked as she made her way across the room.

"Yes Captain. They're moving the torpedo into position now."

"Good. Any activity from the Klingons?"

"Not yet. But if we're stuck here much longer, they will find us." Sulu told her.

"Lieutenant Uhura, did you let Starfleet know we have Harrison in custody?"

"Yes Captain. No response yet." She answered.

"Engineering to bridge. Hello? Captain can you hear me?" Chekov's voice came through the communicator.

"Mr Chekov, give me some good news."

"We found the leak, Captain, but the damage is substantial. We are working on it."

"Any idea what caused it?" She asked. This could make or break Harrison's argument. Or Spock's to that matter.

"Uh, no." Chekov sounded defeated. "But I accept full responsibility."

Edith blinked slowly. "Something tells me it wasn't your fault. Stay on it." She shut down the communication link. "How are we doing on that planetoid?" She asked, switching to McCoy's communicator. "Bones, thanks for helping out. Dr Marcus asked for the steadiest hands on the ship."

"You know, when I dreamt about being stuck on a deserted planet with a gorgeous woman, there was no torpedo!"

"And if I remember correctly, Doctor, it wasn't Carol Marcus either. Now quit flirting and get on with the job in hand."

"So how can these legendary hands help you, Dr Marcus?" Edith cringed from her chair and shared a glance with Sulu.

"Damn it, I knew I shouldn't have sent him!" She muttered, but continued listening to the playful banter before they started fiddling with the weapon.

"The torpedo just armed itself." Sulu told her, as Bones cried out. "The warhead is going to detonate in thirty seconds."

"What the hell happened? I can't get my arm out!"

"Target their signal. Beam them back right now." Edith ordered.

"The transported cannot differentiate between Dr. McCoy and the torpedo. We cannot beam back one without the other." Spock replied.

"Dr Marcus, can you disarm it?"

"I'm trying. I'm trying." Her voice was focused.

"Edith, get her the hell out of here." Edith rolled her eyes. Bones had fallen hard.

"No! If you beam me back, he dies!" And so had she, apparently. "Just let me do it!"

"Ten, nine, eight…"

"Standing by to transport Dr Marcus on your command." How did Sulu manage to sound so calm? Edith placed her left hand on his shoulder, Uhura already had a vice like grip on her right.

"Four, three…" Bones continued counting down. Edith barely realised that she'd been holding her breath until the countdown stopped and she was able to release it.

"Deactivation successful Captain." Spock commented.

"Doctor McCoy, are you alright?" There was no definite answer. "Bones!"

"Edith? You're going to want to see this."
