Explanation
You are told that both Sherlock Holmes and Professor Moriarty engage in “clever deception,” though one of them is “upstanding” and the other is not. You simply need a synonym for “clever deception.” Immorality and wrongdoing do not imply anything clever, and brilliance does not imply deception.
Cunning and subterfuge both fit.
