After three months John finally returned to London. The first thing he did after unpacking was head to Baker Street. London was just like he remembered it. Busy and loud, but still beautiful. When he got to Sherlock's flat he just walked in, not bothering to knock, and ran upstairs.

"Sher-," John began to say but no one was there. He checked every room, even the ones which he had been told on multiple occasions not to enter, but still nothing. Mrs. Hudson was out with friends according to a note she had left on her door and nobody else would have seen where Sherlock had gone.

Suddenly, John realized something was missing but he couldn't put his finger on it. He looked around, checking off things in his head. Skull, check. Violin, check. Laptop, check. Case files… The case files! All of Sherlock's case files were missing, even the ones that weren't so much cases but notes on tobacco ash.

John ran downstairs an out the door, hailing a cab. He had to see Lestrade.

Lestrade looked up from his desk as he heard a loud knock at his office door. He set down his papers and stood up. Slowly, the door was open from the other side to reveal John Watson.

"Oh, hello John. I wasn't expecting you," Lestrade said, sitting down again. "How was your trip?" John entered the office, shutting the door behind him. Something seemed off about the Detective Inspector, almost like he was nervous.

"Do you know where Sherlock is?" John said, watching Lestrade as he fiddled with a pen, refusing to look John in the eye.

"I was going to call you but I didn't was to interrupt your trip," he said, sweating slightly. He cleared his throat and looked up at John. "Sherlock is missing."

Sudden anger boiled up in him.

"What do you mean he's missing!? You should have called me!" John yelled. He took a deep breath before saying, "How long?"

"About two weeks." John breathed deeply, trying to control his anger.

"Two weeks? How?" he hissed, clutching the back of the chair in front of him. Lestrade swallowed hard before finally meeting John's eye.

"Moriarty has returned."
