Black Jack Knight from my steampunk romance ebook The Adventures of Miss Upton and the Sky Pirate is a character close to my heart. He was the first historical hero I wrote and he was definitely a man of his times - resourceful, charming, devil-may-care, protective and utterly ruthless when he had to be.
Jack was based a little on Franics Crawford of Lymond, the main character from the books by Dorothy Dunnett. One of the editions of the 2nd book in that series captured perfectly what I saw in Lymond. This picture is a bit grainy and has been cropped but hopefully you get the idea that he's a bit aloof, thoughtful and mysterious.
