A British mystery

The case

"Does this blazer Really make me look fat?" John asked Mrs. Hudson, turning around in the mirror. "No, dear, you look fine. Now would up you mind helping me clear this junk off?" Sherlock walked into the living room, having just woken up a little while ago. "Ahh no no Mrs. Hudson not that stuff just-just leave it I'll get it later, just- JOHN PUT THAT BACK! " he rushed over to where John was searching for the cheese, and had come across a baggie with what looked like chicken feet. "Sorry, sorry, just wanted to have cheese and crackers or something. They might be hungry, you know." John tossed the chicken feet back into the fridge. They had recently accepted a case for one direction, the popular boy band. John remembered seeing them on crap telly once, something about the ironically named Harry running away, and he assumed that his disappearance was the reason Sherlock was needed. John was brought out of his train of thought by a rap on the front door. It was mrs. Hudson, who had left when she saw the chicken feet. "Boys, there are a group of-well-boys down here to see you and I wasn't sure if I should let them up or not." John walked over to the door and let Mrs. Hudson in. "I'll go get them, thank you for telling me. Now if you could just get Sherlock to tidy up his papers..."  "Of course, dear. Now you hurry up and greet your guests. Sherlock?!" Mrs. Hudson walked towards  Sherlock. John moved down the stairs, sort of exited to meet the new client.  When he reached the landing, he found a group of four boys, excluding the one with large hair. The blonde looked up from a game of Rock Paper Scissors with a black haired man with a large quiff, and the brown haired one and the one with a beard looked up form a hushed discussion.
