Sherlock was completely sure that he had his life sorted out, he had an arch-nemesis, a friend and great job. Sure, he had to put up with Mycroft every now and then but everything else was fine. He just wasn't expecting his father to turn up at a crime scene. He should have, his father was Harry Potter, after all.

Raymond "Red" Reddington, a man of means and ways, has always been one to save himself if need be. A harsh man, cruel at times, he sees himself as a dragon-and no one ever saves the dragon. Well, never let it be said Hermione ever listened to such, because she's about to do just that. Rated T for language and violence.
