Sir Everard Dominey
major
Also known as Dominey, Everard Dominey, Sir Everard, The Everard, Honourable Sir
Dominey steps off the train into a life he barely recognizes: a wife kept behind locked doors, a housekeeper who calls him the murderer of her son, and a neighborhood certain he killed Roger Unthank in a fight over Rosamund. He moves through it with unnerving composure, asking Mangan blunt questions about what people believe and studying the library sherry as if it were evidence. His calm is the story's first mystery — a man who should be shattered, behaving like a man who has rehearsed this homecoming.
Mr. Seaman
major
Also known as Otto Seaman, Herr Seaman
Seaman installs himself in Dominey's life with the ease of a man who has been there before, telling mining anecdotes at the Carlton and charming Mangan over wine. But his real work is quieter: he misses trains on purpose, circles back through the snow, and reads footprints outside a locked room where a spy named Johann Wolff vanished. His instinct, he insists, is never wrong — and it is telling him that something in this house is being hidden from him.
Rosamund Dominey
major
Also known as Rosamund
Rosamund lives behind the care of Mrs. Unthank, tolerated by no one else, fragile in a way that makes her husband's tenderness feel both genuine and strategic. She pleads with him not to rush her, then asks the question that undoes him: you make or mar my life, so you must care a little? Her need for reassurance sits at the center of the novel's domestic tension, because whatever Dominey is doing at the Hall, it keeps costing her something she cannot name.
Princess Eiderstrom
major
Also known as Stephanie, Princess, Stephanie Eiderstrom, the Princess Stephanie of Eiderstrom
The Princess mistakes Dominey for Sigismund Devinter, his Oxford double, and refuses to accept his denials — she has loved Leopold Von Ragastein, she says, and this man wears his face. She tests him with memory, with old endearments, and finally with a kiss that she treats as proof. Her certainty is dangerous because it is partly right, and because a woman that powerful, that wounded, and that unafraid of scandal can expose a man who needs every hour he can buy.
Baron Leopold Von Ragastein
major
Also known as Von Ragastein, Leopold, Leopold Von Ragastein
Leopold exists in the novel first as an absence and an accusation: the man Stephanie loved six years ago, the man whose mannerisms Dominey does not quite reproduce, the man she half-suspects is still alive somewhere in Africa. Her memories of him — his voice, his phrases, his passion — become a kind of forensic test that Dominey keeps failing in small ways. He is the shadow the whole impersonation is built around, and the reason every tender moment with Stephanie carries the risk of discovery.
Mr. John Lambert Mangan
supporting
Also known as Mr. Mangan, Mangan, Bertram, John
Mangan meets Dominey at the station, steers him through the Unthank confrontation, and pours the sherry while gently confirming that everyone in the county believes his client killed a man. He is the reader's guide to the social world — the duchesses, the rumors, the state of the cellars — and he is also a professional watching a client he does not entirely recognize. His mixture of loyalty, curiosity, and legal caution makes him the quiet barometer by which Dominey's performance is measured.
Prince Terniloff
supporting
Also known as The Prince, Terniloff, Prince Von Terniloff, Von Terniloff
Terniloff moves through Carlton House Terrace drawing rooms and snowy shooting parties as the polished face of German interests in England, a man who genuinely believes in peace and says so in private despatches to Potsdam. His distaste for the network of agents operating under his nose sets him at odds with his own service, and his sympathy for the Princess Eiderstrom's anguish over Leopold Von Ragastein reveals a diplomat more loyal to personal honour than to Berlin's methods. His quiet resistance gives the novel's intrigue a moral counterweight, making every secret meeting feel like a betrayal of something worth preserving.
Caroline
supporting
Caroline belongs to the household's shadow-life, bound to Lady Dominey's care and to memories of the night Roger Unthank vanished. Her presence unsettles the returned Everard, because she alone might notice the small wrongnesses in a man who should be familiar. Whether she is nurse, confidante, or keeper of inconvenient truths, her watchfulness makes her a quiet threat to any imposture and a reminder that the past at Dominey Hall has never been properly buried.
Roger Unthank
supporting
Also known as poor Roger, Roger
Roger was a local man whose infatuation with Rosamund Felbrigg curdled into madness after she married Everard, and his disappearance the night of their violent encounter left a stain on the Dominey name that the whole neighbourhood believes. His body was never found, only the story: a temper, a fight, blood on a husband's clothes, and a swamp that swallows what it is given. Whether ghost or grievance, he is the reason Everard's return is met with dread rather than joy, and the reason Rosamund half-believes the dead will not let her husband rest.
Mrs. Unthank
supporting
Mrs. Unthank holds the only position that lets her stay near the family she blames for her son's death, and she uses it without flinching, calling Sir Everard a murderer to his face in his own hall. Her bitterness is not merely personal; it is the village's verdict given voice, and her refusal to be managed by lawyers or masters makes her a living reproach to the returned baronet. As long as she has access to Lady Dominey, the old scandal stays open, and no impostor can feel entirely safe under her stare.
Middleton
supporting
Also known as Mr. Middleton, the faithful Middleton
Middleton is the butler who kept the house standing through years of absence and rumour, loyal to the name of Dominey even when there was no Dominey to serve. His knowledge of the family's habits, its cellars, and its servants makes him both an asset and a hazard to a man claiming to be Sir Everard after a decade in Africa. Every order he receives is measured against memory, and his unspoken judgments carry more weight in the household than any lawyer's assurances.
