The Girl Before

One Folgate Street is an extraordinary house available at an implausibly low rent, subject to conditions: no possessions beyond a minimum, no alterations, no children, and periodic assessment by the architect who built it.

Two women occupy it in succession. The first died there. The second discovers how closely her own experience is tracking the earlier one's.

The rent is low because the house comes with two hundred rules and an architect who enforces them.

Devmark’s reading — not a quotation from the book

Chapters alternate between Emma, the previous tenant, and Jane, the current one, with the two timelines converging on the same events.

The device is the novel's engine: the reader watches Jane repeat a sequence they have already seen fail, which generates dread rather than mystery.

Each chapter opens with a question from the tenant application — ethical dilemmas, personality assessments — with the two women's answers placed together.

It is a genuinely good structural idea. The answers characterise both women economically and are used later as evidence. Several of the questions recur later in altered form, and the change in an answer is used to mark development that the narration itself does not state.

The architecture is described in detail: stone, glass, concealed storage, a system that monitors and adjusts to the occupant, and an absence of anything that could be personalised.

The building is the novel's most effective creation, and the notion of a space that judges its inhabitant is more unsettling than the human antagonist.

Edward's rules are presented first as aesthetic rigour and progressively as something else, and the novel is interested in the point at which a demanding partner becomes a dangerous one.

The material is genuinely observant about how control is rationalised as standards. Delaney is also precise that Edward's demands are never framed as demands, and that each is presented as an invitation the tenant is free to decline.

Emma is unreliable in a specific and disclosed way; Jane is grieving a stillbirth and is more straightforwardly reported.

The contrast is deliberate and the novel plays with the reader's assumption that the earlier narrator is the more trustworthy. Delaney also gives them similar circumstances deliberately, which is what makes the reader's tendency to trust one over the other worth examining.

The house's monitoring system, its adaptive responses and its data collection are handled plausibly and have aged into something considerably more familiar.

Written before smart-home technology was ubiquitous, the novel's anxiety about a building that knows you now reads as ordinary. The house's responses to its occupant — lighting, temperature, the withholding of hot water — read now as a description of something that exists rather than as speculation.

There are several, arriving at close intervals in the final third, and at least one is a genuine surprise.

The density is also the problem: the last fifty pages contain more reversals than the preceding construction can comfortably support. At least one of them also relies on information the reader could not reasonably have deduced, which is the point at which the book stops playing fair.

Efficient and deliberately unremarkable, with short chapters and a great deal of white space, designed for speed.

The two narrators are distinguished more by circumstance than by voice, which is a limitation the structure mostly conceals. The chapters are also very short, frequently under a thousand words, which is a commercial decision that suits the alternating structure well.

The relationships involve control, consent and power in ways the novel examines and occasionally uses for effect.

The distinction between interrogating a dynamic and deploying it is not always maintained, which is a fair criticism of the book. Readers should expect explicit material involving power and consent, and should know that the novel's position on it is less clear than its subject matter requires.

A television series adapted it with several significant changes, including to the characters' circumstances.

The novel's structure — two timelines in the same rooms — is well suited to screen, and the adaptation makes reasonable use of it. The series also expands both women's lives outside the house, which dilutes the claustrophobia that the novel's confinement to a single building achieves.

Readers who want a fast, well-constructed domestic thriller with a genuinely original setting.

It is among the better books in this category, largely because the house supplies something the others do not. Readers tired of the format may find the architecture enough to justify it.
