Dr. Rance, a psychiatrist sent from the government to check on how psychiatric clinics are being run. He is a brutal, power-mad doctor, and he tries to certify everybody as insane, though it is obvious that he is the only one who is truly mad.
Mrs. Prentice, Dr. Prentice’s wife. During a brief stint as a chambermaid at the Station Hotel, she was raped in a linen cupboard during a power outage (hence her inability to recognize her attacker as her fiancé, Dr. Prentice). She is a blasé, disillusioned woman who belongs to a lesbian women’s group. The failure of the Prentices’ marriage is attributed to the fact that Mrs. Prentice refused to consummate their marriage during their wedding night.
Nicholas (Nick) Beckett, a page boy from the Station Hotel, now an applicant for the job as Dr. Prentice’s secretary. Nick is an accomplished typist and blackmailer with an insatiable sexual appetite, exemplified by his attempted rape of Mrs. Prentice (his mother) and the accomplished molestation of “a section of the Priory Road School for girls” on the same night. He turns out to be Geraldine’s twin brother and the Prentices’ son.
Geraldine Barclay, an applicant for the position as Dr. Prentice’s secretary. A young, attractive girl, she is trusting and believes in telling the truth. Although she is the only person with any morals (except, perhaps, for Sergeant Match), she gets the brunt of Dr. Rance’s abuse, as when he cuts off all of her hair. Her ignorance of the whereabouts of pieces missing from a statue of Winston Churchill seems symbolic of her purity and naïveté. Ultimately, it is revealed that she is Nick’s twin and the Prentices’ daughter.
Sergeant Match, a policeman looking for Geraldine Barclay and Nicholas Beckett. His more important mission, however, is to find Geraldine and Sir Winston’s missing parts; of lesser interest is his charge to find the molester of the girls from Priory Road School. Having accomplished his main task, which is of national importance, Match has no qualms about forgetting everything else he has witnessed, though this willingness may be related to the large amount of narcotics that Dr. Prentice has given him.
