Antony Gillingham
major
Also known as Antony, old Gillingham, Gillingham, Tony, Mr. Gillingham, Dear Mr. Gillingham, dear Mr. Gillingham
Antony arrives at the Red House as a guest of Bill Beverley and is almost immediately swept into the aftermath of Robert Ablett's murder, coolly taking charge when Cayley falters. He is curious, unflappable, and privately skeptical of the tidy story everyone else accepts, treating the case as a puzzle to be solved rather than a tragedy to mourn. His willingness to keep asking uncomfortable questions drives the investigation forward and unsettles the household.
Bill Beverley
major
Also known as Bill, Good old Bill, Bill Beverly, Beverley, Dear old Bill, William Beverley, William
Bill is a guest at the Red House, friendly with everyone from the Major to Cayley, and he instinctively assumes the best of people he has shared breakfast and billiards with. That very openness makes him a foil to Antony's suspicions, and his inside knowledge of the house and its routines becomes quietly valuable. His readiness to believe Cayley innocent is exactly the kind of assumption the mystery keeps testing.
Mark Ablett
major
Also known as Mr. Mark Ablett, Mr. Mark, Dapper little Mark, Mark, Mark Ablett, Mr. Ablett, kind Cousin Mark, Mister Mark Ablett
Mark is the wealthy cousin whose hospitality draws artists, actors, and hangers-on to the Red House, and whose unwelcome brother Robert arrives from Australia demanding money. He is generous and self-absorbed in equal measure, a man who likes to do the talking and to be admired. His vanishing the same afternoon Robert is shot turns a country-house weekend into a manhunt and forces everyone to reconsider how well they knew their host.
Matthew Cayley
major
Also known as Mr. Cayley, Cayley, Matthew Cayley, Faithful Cayley, Cay, Mr. Matthew Cay
Cayley is cousin, secretary, land-agent, and companion rolled into one, the man Mark leans on and calls 'Cay'—and the first person on the scene when Robert's body is found. He is practical, discreet, and visibly shaken, yet his calm explanations and his habit of steering the conversation away from awkward questions make Antony watch him closely. As the household's fixer, he sits at the center of everything the investigation must untangle.
Robert Ablett
major
Also known as Stanton, Robert Ablett, Robert, brother Robert, Stanton Robert Ablett, Mr. Robert Ab, Mr. Robert
Robert is the estranged brother whose unexpected return from Australia, announced by a letter at breakfast, throws the household into unease. He is coarse, mocking, and clearly after money, and his exchange with the lodge-keeper Amos shows a man spoiling for a confrontation. His corpse in the office is the crime that sets everything in motion, and the question of who wanted him dead—and why—hangs over every conversation that follows.
Elsie
supporting
Also known as the unhappy Elsie, poor Elsie
Elsie is a servant whose testimony the police take seriously even as Cayley dismisses it as the imaginings of 'girls of that class.' What she heard through the office door—voices, and Mark's distinctive tones—quietly contradicts the tidy version of events the household prefers. Her evidence becomes a small but stubborn thread that Antony refuses to let go, and it keeps the possibility of Mark's guilt alive against the general assumption of his innocence.
Miss Norris
supporting
Also known as Norris
Miss Norris is a guest at the Red House whose theatrical instincts make her both entertaining and dangerous. When she mocks Mark Ablett in front of the others, his wounded vanity becomes the lever Cayley needs to manipulate him. Her presence matters because she unknowingly supplies the humiliation that triggers the private performance at the heart of the mystery.
Inspector Birch
supporting
Also known as Birch, Inspector
Inspector Birch leads the official investigation into Robert Ablett's death, questioning witnesses at the coroner's inquest and sifting the unreliable sightings of the vanished Mark. He is a sound, close-mouthed man who does not tip his theories, which makes him both a useful foil and a quiet threat to Antony's private inquiry. His handling of the case shapes how much the amateur detectives can learn from the official record.
Audrey Stevens
supporting
Also known as Audrey, Stevens
Audrey Stevens works in the housekeeper's room under her aunt Mrs. Stevens, absorbed in small domestic pleasures and the gossip of a brother no one has seen in fifteen years. Her cheerful, unguarded talk with her aunt opens the novel and plants the first unease about Mark Ablett's Australian visitor. She matters because her ordinary vantage point, close to the household but outside its secrets, gives the reader the first thread of the mystery.
Mrs. Stevens
supporting
Also known as Stevens
Mrs. Stevens runs the bachelor household with a housekeeper's pride and a sharp eye for what she has and hasn't seen. She insists she has never heard of Mark's brother in five years, a plain fact that quietly contradicts the official story. Her stubborn, unpretentious testimony matters because it establishes the household's baseline of truth against which the later deceptions are measured.
Mrs. Norbury
supporting
Also known as XV Mrs. Norbury, Norbury
Mrs. Norbury is a matchmaking neighbor who has decided that the artistic, well-connected Mark Ablett is the ideal husband for her daughter, beard and all. She confides in Antony Gillingham with a mother's readiness, revealing her own hopes and, indirectly, the tangled feelings among Angela, Mark, and Cayley. Her talkative certainty matters because it exposes the romantic and social pressures surrounding the Red House just as the mystery tightens.
