BRINDSLEY MILLER - a young sculptor, mid twenties, intelligent and attractive, but nervous and uncertain of himself.
CAROL MELKETT - Brindsley's fiancee. A young debutante; very pretty, very spoiled; very silly. Her sound is that unmistaktable, terrifing debutante quack.
MISS FURNIVAL - a middle-aged lady. Prissy and refined. Clad in the blouse and sack shirt of her gentility, her hair in a bun, her voice in a bun, she reveals only the repressed gestures of the middle-class spinster -- until alcohol undoes her.
COLONEL MELKETT - Carol's commanding father. Brisk, barky, yet given to sudden vocal calms which suggest a deep alarming instability. It is not only the constant darkness which gives him his look of wide-eyed submission.
HAROLD GORRINGE - the bachelor owner of an antique-china shop, and Brindsley's neighbor, Harold comes from the North of England. His friendship is highly conditional and pssesive: sooner or later, payment for it will be asked. A specialist in emotional blackmail, he can become hysterical when slighted, or (as inevitably happens) rejected. He is older than Brindsley by several years.
SCHUPPANZIGH - a German refugee, chubby, cultivated, and effervescent. He is an entirely happy man, delighted to be in England, even if it means being employed full time by the London Electricity Board.
CLEA - Brindsley's ex-mistress. Mid-twenties; dazzling, emotional, bright, and mischevious. The challenge to her is to create a dramatic situation out of the darkness is ultimately irresistable.
GEORG BAMBERGER - an elderly millionaire art collector, easily identifiable as such. Like Schuppanzigh, he is German.
