No, he's not here. The last time I saw him was about two hours ago, I caught up to him where he was tailing that Moriarty bloke and he said he had something to do. He was fine then, though.

[Then again, two hours is a long time in Sherlock-time.]

If his phone's out of service, not much you can do but head home? I'll keep an eye out in case he shows up.
