Windsor is Mrs. Stafford-Smyth's butler. It is Windsor who comes to visit Mrs. Stafford-Smyth when she is being cared for at Luke's doctor's office. He is unhappy with his mistress's habit of traveling and "gadding about" as he calls it. When Belinda and Mrs. Stafford-Smyth return to Boston, it is Windsor who is in charge of ordering the carriage and traveling with them about town.
