"Is this... what are you implying?" Frowning, Watson rose from his chair, not sure whether he ought to be angry or offended or merely quietly perplexed. "Are you seriously accusing me of being unfaithful?" He gave a low bark of laughter, but there was no humour in it at all. "Have I ever given any indication..."

Breaking off, Watson drew a cigarette from his pocket, and lit it. He could not have this conversation without some sort chemical support; it was far too late, and it had been far too busy a day. "What exactly do you think happened?" he asked, gesturing wildly with his lit cigarette. "Do you somehow deduce that she and I shared carnal knowledge of each other in the cab?"

He was incredulous, and he was hurt, and he was angry at having his good mood so thoroughly dashed.
