Albert Moriarty and Mycroft Holmes were both in Mycroft's office. Albert had just finished reporting about the incident with the recent opium dealing case and how it ended.

Mycroft: "I wonder how much had been planned in this incident." Mycroft said, while propping his elbows on the desk, folding his hands and leaning in a little. He had his suspicions about the end of the case.

Albert: "It was pure coincidence, director." Albert answered simply, with a hint of his usual smirk.
