Hey this is just a drabble so I'm might turn this into a full story but dont know if it will happen but here it goes!
Sherlock Holmes was at his flat typing on his laptop while his roomate, John Watson was fiddling with his keys when the doorbell rang followed by a movement of quick steps. Sherlock remained still while John still fiddling with his keys, "Why don't you get the door? You've gotten no cases since the Jim's case" Sherlock respond without looking up "Because I just found this new murder game and I want to finish it by today after all, I am the best detective in London." John just raised an Eyebrow, sighed and got up and went to the door. John opened the door, while splashes of rain responded to his face. "Bloody hell" John cursed and looked left and right and just shrugged and was about to close the door when he heard a wail. He looked at the doorstep and saw a wooden basket and a pink blanket. "Eer...Sherlock? You might want to see this" He brought the basket inside and uncover the blanket showing a small baby girl.
