The Seat of the Scornful (Dr. Gideon Fell, #14)

Judge Horace Ireton didn't care about the letter of the law. He was interested in administering absolute, impartial justice as he saw it. To some, his methods of meting out justice made him seem hardly human, for they were coldly calculated - the same type of "cat and mouse" technique that he used in his chess games with Dr. Gideon Fell, the elephantine detective. The system, as he explained it, consisted in "letting your opponent think he's perfectly safe, winning hands down: and then catch him in a corner." But the system was not infallible. One day Judge Ireton was found with a pistol in his hand, beside the body of his daughter's fiancé, a man he had every reason to dislike, as many people knew; and he found that when one was on the inside looking out, the game had to be played differently.
