This is a list of the recurring characters in the Albert Campion novels and short stories by Margery Allingham.
Friends and acquaintances
William Faraday ("Uncle William") first appears in Police at the Funeral, when he is in his sixties and living at the house of his domineering, Victorian mother, Caroline Faraday. He appears again in Dancers in Mourning, by which time his mother has died and he has become a bestselling author and librettist. His death occurs before the start of The Beckoning Lady.
Renee Roper first appears as a theatrical landlady in Dancers in Mourning. Then in More Work for the Undertaker she has become the landlady of the eccentric Palinode family; she asks Campion to investigate the mysterious deaths of two members of the family.
Guffy Randall first appears as part of the foxhunt which comes to Campion's rescue in The Crime at Black Dudley. He appears again in Sweet Danger where he helps Campion in his investigation. He marries Mary Fitton, Amanda's older sister. Their daughter Mary appears in The Beckoning Lady. Their grandson Sam Ferris is one of the two schoolboys who appear in The Mind Readers.
Thos. T. Knapp first appears in Mystery Mile as a spiv with a talent for tapping phones, a permanent sniff, an awful old mother and considerable physical courage. He pops up throughout the series, with an offstage role in Coroner's Pidgin, and features in The Mind Readers, employed by a forgotten wartime comms establishment on a bleak estuary island.
L. C. (Elsie) Corkran appears in both Mr. Campion's Farthing and Mr. Campion's Falcon as an official and then ex-official with connections to "security". His surname is almost certainly a reference to "Stalky" Corkran, the protagonist of Stalky & Co. by Rudyard Kipling, who was modeled on Lionel Dunsterville.
