A: Two. Tucker Thursnoose, a court watcher known as Courtly Tuck, who hadn’t missed a day in Judge Pickscreed’s Southern District of New York federal courtroom in two decades, was dropped in an early revision because his role, principally to comment on the judge’s procedures, was too insubstantial to warrant clogging a reader’s memory. He would not, in any event, have appeared after Chapter 1. Another character was named in a later chapter only in passing in a single line; he remains in the book only by reference to his position.
