I doubt he'd be watching the child of a police detective, so a private detective? Too bad I know dear Sherlock doesn't 'work with'- [He pulled his hands from his pockets and slouched down, making very mocking air quotes as he spoke.] other detectives, he hardly works with his partner. So how about you stop LYING. [He shrieked at the child, taking a single step forward and projecting his voice as much as possible int the small room.]

[Really, what he was interested in was just how easily frightened the child was or if he was lying about that as well.]
