False Value
A deliberate reset that feels different but keeps the series’ fascination with systems, power and practical magic.
What it’s about
Peter takes a job inside a technology company while investigating its secretive founder and the possibility that old magic has found a new operating system.
Peter takes a position at a London technology company whose founder and systems attract unusual attention. Corporate rules, guarded information and the possibility that older magical questions have acquired a new setting shape the opening. Peter narrates from within the job, so the reader has to judge what is routine workplace behaviour and what might be part of an enquiry. The humour is still his, but the familiar police surroundings are deliberately less visible. The premise brings a detective trained to test claims into a business that presents its own account of how things work. Expect modern office life, secrecy and a speculative question about power; no knowledge of a particular computing system is needed to understand the initial problem.
Setting
A London technology company becomes the principal workplace, set against the Folly's existing institutional history. The corporate setting is fictional; the book's questions about secrecy and systems do not claim that a real firm operates this way. Contemporary London is still present, though office access replaces streets and river jurisdictions as the first barrier Peter encounters. The linked story-world guide gives context for the Folly without turning this corporate case into a map of the city.
Why it works
The change of setting gives the series a different texture after the preceding arc. Technology culture, corporate security and artificial intelligence sit beside magical theory in a story that initially withholds Peter’s full purpose. The structure can feel intentionally disorientating, but the central idea—old power wearing modern clothes—is a strong fit for the series.
After a major earlier arc, the series needs a fresh setting that can bear more than a change of wallpaper. The technology workplace does that by replacing the Folly's familiar rules of access with a company's own hierarchy, vocabulary and habits of concealment. Peter knows how to ask a useful question, but a corporate answer may be designed to sound complete while revealing very little. The comedy comes partly from his ability to recognise that manoeuvre without being immune to it.
Artificial intelligence and magical theory can both invite vague talk about systems nobody else is allowed to inspect. The book is stronger when it makes that resemblance a question about responsibility rather than an excuse to declare the two the same thing. Peter's guarded viewpoint helps: he observes colleagues and the founder, but the reader cannot always assume that an apparently simple observation exhausts his purpose. That structure changes the ordinary intimacy of his first-person account. We are still hearing his jokes, yet we must also pay attention to what he chooses to explain.
Some readers will find the withholding an appealing reset, while others may miss the direct detective momentum of a murder interview. Technical talk can feel deliberately alienating when the company controls its terms. The novel makes the discomfort part of the setting rather than pretending that code and magic are identical marvels. Its real continuity with the earlier books lies in the question of who gets to define an apparently powerful system and who has to live with the consequences. That is a useful new problem for Peter's practical habits of mind.
How the audiobook sounds
Holdbrook-Smith handles corporate types, technical dialogue and familiar Folly characters without making them sound as though they occupy different novels. Peter’s controlled, slightly guarded narration is particularly useful while the book keeps parts of his plan from the listener.
The change of workplace asks for a controlled Peter voice. He can still sound amused or sceptical, but a public conversation inside a company is different from talking with an established police colleague. Listen for the difference between an easy aside and a response that gives away only what it must. The recording makes those changes in register audible without requiring a listener to know the machinery behind every corporate term.
A technical explanation can be more demanding in audio than on a page, where an unfamiliar phrase is easy to reread. The narration helps by keeping exchanges between people clear, even when their preferred description of a system is less clear. A commute may suit a self-contained workplace scene; longer sessions make the book's deliberately guarded perspective easier to hold together. Returning Folly voices, where they appear in the book, provide a contrast with the newer corporate environment. Anyone looking for the same loose investigative cadence as the debut should expect a more carefully withheld account, and can choose print if repeated technical detail is a concern.
Can I start here?
Read Lies Sleeping first. This begins a different phase, but Peter’s personal and professional history still matters.
Read Lies Sleeping first. This begins a different phase but assumes the reader knows Peter's professional and personal history. It may suit you if the questions about institutional power in the earlier novels interested you as much as their magical cases. If you liked a mystery in which a workplace controls information, the company's guarded culture provides plenty to notice. Readers who require Peter to lay out his plan immediately may find the structure frustrating, and technology language is more prominent than in the London street cases. It is a reset for an established reader, not a self-contained introduction to the Folly.
