"That fateful night seems at first glance to fill that hole perfectly. A donut hole in the donut's hole. But we must look a little closer. And when we do, we see that the donut hole has a hole in its center - it is not a donut hole at all but a smaller donut with its own hole, and our donut is not whole at all!" - Benoit Blanc
"I suspect foul play!" - Benoit Blanc
Detective Benoit Blanc is "The Last of the Gentlemen Sleuths", the secondary protagonist in Knives Out, and the sole protagonist in the upcoming Benoit Blanc Mysteries film franchise (name not official yet). Played by Daniel Craig.
Blanc is considered "The Last of the Gentlemen Sleuths" and in many ways is a typical portrayal of that kind of character. He's flamboyant, practical, gentlemanly, somewhat eccentric, a cigar chomper, but incredibly clever, intelligent, and an overall good detective. Despite these archetypes usually being British (as well as being played by a British actor), Blanc talks like a member of the Southern aristocracy with an accent that can only be described as a "Foghorn Leghorn Drawl".
Even though Blanc is as sneaky, abrasive, relentless, and snarky as most gentlemen sleuths, Blanc is actually much nicer than most examples of this archetype. He's less of a womanizer (which is ironic and a little tongue-in-cheek cause he is played by James Bond actor, Daniel Craig) and is more of an overall pleasant, friendly, and well-meaning man. Even his manipulative sides are for good reasons. He takes his job seriously and overall wants justice to be served. He can appear bumbling on occasions but is no doubt has a brilliant mind as he was able to tell right away that Marta had something to do with Harlan's death as he saw a strain of dried blood on the shoe she wore the night Harlan committed suicide.
