On an episode of the show Elementary, Sherlock describes his father as "[something] par excellence". I can't remember what the [something] is. I used to just google Morland Holmes and the first thing up, would have the quote. I have looked in Wikipedia, and TV fanatic. Unfortunately, I can't remember which episode it's in or the names of other places I have looked. I don't think there is anything else I can tell you.
The dialogue you're looking for is:
influence peddler par excellence
In fact, it's quoted in the Sherlock Holmes wiki.
He is described as an international consultant, and an "influence peddler par excellence".
