Holmes?"
Holmes turned to see Watson looking at him with a faintly amused expression. He was holding up a wig that Holmes had carelessly left in his chair earlier that morning. "What might this be?"
"I would have thought that obvious, Watson," Holmes said dismissively. Internally, he hoped that Watson had not realized where the disguise was from. "It is a wig. One of mine to be precise, so if you could-" He reached a hand out, and Watson gave the wig to him. Holmes hastened into his bedroom to put it away.
"Strange," Watson's voice carried through from the sitting room. "I'm sure that looks familiar." His voice still held a tone of amusement. "I wonder where I could have seen it? Oh, I know! It looks a lot like the hair of a man that helped with my bags yesterday. Now, I wonder how that could be?"
Holmes slowly walked back into the sitting room, to see Watson smirking at him. "Honestly, Holmes. I'm not an idiot. I've lived with you long enough to know when you are in disguise. I just want to know why you did it?"
"I was in the area for some research, and I was already in disguise, so-" Holmes flustered his way through.
Watson laughingly waved him off. "Thank you, Holmes."
"No bother."
