Rule 10: Whatever you do, don't be late. Especially if it's because of a case, then you may want to tread with extreme caution (but do it quickly).

Rules of Engagement

Sherlock Holmes always imagined his death would be a dramatic event.

As a consulting detective with his past and reputation he knew he lived dangerously, he had enemies everywhere he looked and he knew there was always a possibility that one day he would wake up for the last time and his life would draw to a close in a most unexpected way.

He did not, however, imagine that to be this day. Nor did he imagine his killer would be the small, mousey pathologist who in just a few short hours would become his wife. Unfortunately as the time ticked by the scenario was looking more and more promising and he bit his lip as he glanced at John and the doctor just glared flattering his spot on the soggy ground. They were both filthy, clothes torn and John had a decent sized bump on his head that would be difficult to explain to Mary. (She already disliked him, how was he supposed to explain to her that her husband may or may not have gotten into a row with a man twice his size and narrowly avoided a bullet that was intended for his skull before they both took a dive in a very questionable looking pond in an attempt to escape?)

"I hope you know I hate you," the soldier said suddenly, trying his best to wring out his dripping wet jacket with a look of disgust.

Sherlock just sighed and folded his hand under his chin. "I know."

"And Molly is going to murder you. You know that too right?"

"Yes, I know."

"And your wedding is in about two hours and we're stuck out here in the middle of nowhere, sopping wet and smelling like a sewer. Did you know that 'oh great one'?"

This time Sherlock growled and rolled his eyes, "Yes John, I know! Now please stop your whining and give me your phone so we can get out of here."

He heard the older man grumble before he tossed the now water-logged device at his friend and Sherlock yelled in frustration, tossing it somewhere behind him where it landed with a rather loud thud. If looks could kill Sherlock would be nothing more than a puddle on the ground.

"Well," he announced, "It looks like we'll be walking."

He glanced at the empty road just a few yards away and tried to ignore the heat of John's glare as he trudged uncomfortably in his wet clothes and prayed to every god in the world that he was not late for this wedding. It would be bad enough to leave Molly waiting but he knew, as well as John and just about everyone else, that if she found out he had decided to take a case while she went out with Mary and a few friends and may or may not have gotten lost in the country side just hours before the big event that things would not end well for him.

While the two weren't far from the city they were still cutting it close and being on foot was not helping their cause. As they walked the tension between them grew at an alarming rate. Sometimes John thought he would never understand what went on in his friend's head, why he would think it was a good idea to tale a case the night before his own wedding was beyond him. A simple stag party like his own was what he had planned with Greg and Mike but of course Sherlock had different plans and it had been too late when John finally realized their taxi was not headed in the direction of his favorite pub.

From that point on the rest of their night and most of their morning had consisted of arguments, big men with guns and more running than he had ever done before. It was pure luck that right before the case had gone straight to hell he had managed to send a quick text to Greg and ask that he keep Molly and Mary busy until they got there.

Only that had been almost an hour ago and since then his phone had been destroyed by the water and he was almost positive either Molly was going to kill Sherlock or Mary was going to kill them both.

Either way things were not looking good.

…

"I'm going to absolutely kill him," Molly muttered aloud to the room. She was pacing furiously in her gown, palms smoothing over the white skirt nervously. Mary looked up from her spot in front of the mirror, offering her a sympathetic glance before dialing her husband's number again in frustration. It once again when straight to his voicemail and she growled before she dropped it onto the table and stood up.

"Don't get too worked up, they probably just had a little too much fun last night." She rubbed Molly's arm soothingly but it offered little comfort.

"They should still be here by now, Greg and Mike are here and they went out last night too." She gnawed at her bottom lip and looked at Mary with a hint of uncertainty. "You don't think he's changed his mind do you?"

Mary gawked at her. "Of course not! That man may be a complete nut but he loves you. Even I can see that and I am absolutely certain that he would never leave you hanging like this."

"But-" Molly's doubts were interrupted when the door swung open and a very nervous and uncomfortable looking Greg appeared in the doorway. He pulled at the tie around his neck and looked at Molly.

"He's here."

...

For the most part everything seemed to run smoothly after John and Sherlock arrived. They had managed to clean up and get to the chapel with just minutes to spare and Sherlock was at his spot in front of the altar by the time Greg had gone to collect Molly. He jumped, somewhat startled when the music began to fill the room and John gave him a smile and a pat on the back.

"Here we go. First day of the rest of your life."

Sherlock swallowed and watched the people in front of him slowly complete the walk down the aisle, feeling as if time was passing as slowly as possible. For once he wasn't bored, if anything he would say he was nervous. The feeling was only intensified when Mary appeared in a red dress that went well with her hair, followed by Molly who Sherlock was sure never looked more beautiful.

It was natural beauty too, he could detect almost no traces of makeup other than the gloss on her lips and the faintest hint of mascara on her lashes. Her skin was pale against the dress, a creamy alabaster that seemed to glow under the lighting and he longed to reach out and run his fingers across it. The dress itself was lovely as well;it was strapless and hugged her waist, showing off her curves until it blossomed out at her hips, the train trailing out behind her.

She caught his eye as she approached and the blush that ran across her cheeks was one of the most endearing sights he'd seen in a while. She smiled at him as she and Mary finally reached the altar and he offered her a hand that she took, squeezing his fingers tightly. Mary leaned over, pecking her cheek and for the first time noticing the bruised bump on John's head. Her eyes bugged and she glared at both he and Sherlock while guilty eyes refused to meet hers.

As they settled in and the pastor began to recite Molly leaned over to whisper minis ear. "I thought you'd changed your mind."

She felt his fingers curl tighter around her own. "I've already told you, I'm never going to leave you again. Three years was long enough enough and I am not a patient man."

The service had been swift and it had only taken what felt like minutes before they were officially bride and groom. When the announcement tore through the room Sherlock had taken Molly into his arms and kissed her, ignoring John's clapping, Mrs Hudson's tears of joy and Greg's screeching whistle from the front row. At that moment Molly was the only thing that mattered.

He felt her smile into his lips, her fingers running through his hair until she stopped and her eyebrows knit together. He felt something tug at his hair and suddenly Molly presented him with clump of moss he had picked up in the water earlier. He turned and looked at John but he was in a very serious and only slightly hushed 'conversation' with Mary. It looked like he would have to explain this one on his own.

"Where on earth did this come from?" She asked, looking at him sternly. He flashed her best smile and pulled her closer as they made their way back down the aisle as husband and wife.

"Oh John and I decided to take a swim this morning. Nothing to worry about."

"Sherlock..."
