SIR REGINALD FITZBUTTRESS - A plump man in his mid-forties. Definitely an English gentleman. He is a bit unnerved when he is found out, but gains confidence when he feels things are going his way.
LADY GWENDOLYN FITZBUTTRESS - A good looking woman in her early 30's who is every inch a lady. She is properly indignant at her husband's supposed infidelity, and even perhaps a little hurt.
THE INSPECTOR - in his late 30's. An efficient Sherlock Holmes type, but has a hard time remembering names. Nothing phases him and he can appreciate a "fiendishly clever" scheme even when he is the brunt of it.
CATHERINE CORNELIUS - a beautiful young woman in her twenties. Out of all of them, she is the one with all the answers and her coolness stems from the knowledge of this fact.
FREDDY - A young fortune hunter in his early twenties. He is cocky and a bit Cockney too.
