Anything else other than a roll of one on your check you would have spotted them, or at least the pickpocket. Just so you know though, in a meta-game sort of way, the high target for your sense trouble indicates these guys are pretty streetwise.
Now if I understand things, next it's lunch, Scotland yard then lawyers, right?
