A Fall at the Usher Hall
Isabel Dalhousie is at a concert in the Usher Hall, Edinburgh's main concert venue, when a young man falls from the upper balcony — 'the gods' — to the ground below. He does not survive. In the seconds before he falls Isabel catches his face, and what she sees there is not resignation but shock. The image stays with her. The police, working from the obvious, treat the death as a fall or a suicide. Isabel cannot make that reading fit the expression she saw. The novel's engine is not a clue but a moral itch: she was there, she saw something, and she is not sure that being a bystander leaves her free of obligation.
The Moral Obligation of a Witness
Isabel edits the Review of Applied Ethics and thinks professionally about duty, so the question of whether to involve herself is one she cannot leave alone. She is aware that curiosity is not the same as obligation, and she interrogates her own motives more rigorously than most detectives ever do. She concludes that moral proximity counts: she was in the hall, she saw his face, and that accident of position creates a duty that would not exist had she read about it in the newspaper. The reasoning is characteristic of the book — Isabel arrives at action through argument rather than instinct, and the argument is at least as interesting as the action.
Isabel's Edinburgh
Around the investigation McCall Smith builds Isabel's settled world. She lives alone in a large house in Merchiston, comfortable on inherited money. Grace, her housekeeper, holds firm views and an interest in spiritualism that Isabel treats with amused tolerance. Her niece Cat runs a delicatessen and is the person Isabel is closest to. A wild fox Isabel calls Brother Fox comes and goes in the garden, and she thinks about him with the same seriousness she brings to everything else. This texture is not decoration; the domestic scenes carry as much of the novel's weight as the mystery does.
The Dead Man's Flat
The young man is identified as Mark Fraser, who worked in the funds department at McDowall's, a brokerage. Isabel makes contact with the two people who shared his flat: Henrietta 'Hen' Duffus and Neil Macfarlane. It is a delicate approach — she has no standing, no authority and no relationship to the dead man, and she is conscious throughout of intruding on grief for reasons she has had to justify to herself. The flatmates are the first people to give Mark a shape beyond the body on the floor of the Usher Hall.
A Story About Insider Trading
Neil Macfarlane supplies Isabel with a motive. Mark, he says, had discovered insider trading at McDowall's — he had been talking quietly about a colleague whose dealing he could prove — and had been subtly threatened. Mark was frightened, and feared for his safety. It is exactly the shape a mystery reader expects: a young man with dangerous knowledge falls to his death weeks later. Isabel takes the lead and runs with it. The reader should note who handed it to her.
Paul Hogg and the Gallery
Isabel had met Paul Hogg at an art gallery before any of this began, and discovers by coincidence that Mark Fraser worked for him at McDowall's. She arranges to see him again, ostensibly sociably, actually to fish. Paul is an art collector and an easier man to like than to suspect. The scenes work as social comedy as much as investigation: Isabel is trying to extract information from someone who thinks he is simply having a pleasant conversation, and she is uncomfortably aware that this is a form of deception she would condemn in the abstract.
Minty Auchterlonie
At Paul's house Isabel meets his fiancée, Minty Auchterlonie, and dislikes her immediately. From that dislike she constructs a case: Minty, she decides, has the right combination of ruthless ambition and immorality to use Paul for insider information, and therefore a motive to want Mark Fraser silenced. This is Isabel's most revealing stretch. A philosopher who thinks carefully about the ethics of judgement is here reasoning backwards from an antipathy, and the novel lets her do it without comment. Appearance and reality diverge, and Isabel is the one confusing them.
Johnny Sanderson and a Break-In
Isabel's friend Peter Stevenson, who plays clarinet in the cheerfully awful amateur Really Terrible Orchestra, arranges for her to meet him and Johnny Sanderson at one of its concerts. Sanderson is a figure from Edinburgh's financial establishment and knows how that world handles its own. Afterwards, Johnny Sanderson breaks into Isabel's house. To Isabel this looks like confirmation that she is close to something dangerous, and it pushes her further down a line of enquiry that is leading nowhere.
The Orchestra Programme
The insider-trading investigation, which has consumed most of the book, turns out to be a red herring — and it was Neil Macfarlane who planted it. What undoes him is domestic and tiny: Isabel realises that Neil had a copy of the orchestra programme from that night, which means he was at the Usher Hall when Mark fell. He had never said so. The clue is characteristic of the novel's scale — not forensics, not a confession extracted under pressure, but a piece of paper that should not have been in the flat.
Neil's Confession, and Isabel's Decision
Neil confesses. He and Mark argued at the concert about Mark's relationship with Hen, their flatmate, of which Neil was jealous. Neil gave him an elbow — a small shove, he says, not meant to hurt him and certainly not to kill him — and Mark went over the railing. Isabel weighs it and concludes that Neil is telling the truth, and that punishing him would be wrong. She does not report him. There is no arrest, no trial, no conventional justice. The novel ends with a private ethical judgement made by a woman with no authority to make it, which is precisely the point: Isabel has spent the whole book arguing that proximity creates obligation, and the obligation she finally accepts is to decide, herself, what should happen to Neil Macfarlane.
