Sherlock didn't like taking many personal cases, but when he went downstairs and found his favourite lady crying, he knew he'd do anything to stop that. So she told him a story about her past - one she had hidden very well. A mistake she made in her younger days, and that today was the yearly reminder of what she had done. She offered him a case, something to keep him busy, and if it kept Mrs Hudson happy he'd keep getting fed when he needed to.
That was a few months ago. A lot of stuff had changed for him but he'd just about solved Mrs Hudson's case, and now was just putting the finishing pieces back together. Before he told Mrs Hudson, he just needed to wait for one person to arrive.
He didn't have to wait long; after not five minutes of being ready, there was a knock on the door of 221B and he could hear the voice of Molly being greeted by his landlady. Then he heard the footsteps of them both coming up stairs and he knew that if he didn't do this properly, the effects would be disastrous.
*knock on the door*
"Come in," Sherlock said.
"Right, Molly, Mrs Hudson, I'm glad you're both here. Take a seat. I have something to discuss with you."
They both took their seats on his sofa, and he pulled up a chair and sat down in front of them. They felt a bit like clients.
Mrs Hudson was the first to speak. "What is it, Sherlock? Is something wrong?" "Is this for a case?"
Do you need our help with something? What about John, I'm sure -" Molly started, sounding a little worried.
"It's not for a case, no. If you would just let me talk, you'll find out," Sherlock said, staring to get annoyed.
They both looked at each other, expecting the other to know the answer, then they both turned to look at Sherlock. What they didn't know was whatever Sherlock was going to tell them would change their lives forever...
