Stone and Sky
A broadening tenth novel that uses Scotland and dual narration to prevent a long-running series from becoming too comfortable.
What it’s about
Peter’s Scottish holiday becomes an investigation in a landscape where London’s understandings of magic and allegiance no longer provide reliable rules.
A Scottish holiday becomes an investigation when Peter's circle encounters a death away from its usual London ground. The opening asks what the Folly's working assumptions can tell them in a place with different local histories and authorities. Peter's experienced voice remains part of the story, while another established perspective has more room than usual. The change of setting brings landscape, travel and unfamiliar arrangements into a case that still begins with a practical question about a body. Expect a later-series novel that knows the London rules well enough to question their reach. Its premise makes the journey itself consequential without requiring a reader to know anything about an ending, an antagonist or the fate of the people travelling.
Setting
Scotland supplies the principal geography, beyond the London river map's remit. The Folly remains part of Peter's training and professional assumptions, but the book asks how far those assumptions travel. Its local powers and relationships belong to the fictional world, not a guide to Scottish institutions or history. The wider story-world guide is the right context link; a self-guided London walk would give a misleading impression of where this case takes place.
Why it works
Taking the series away from London again creates room for different histories, powers and relationships. Peter is more experienced now, so the tension comes less from discovering that magic exists and more from recognising that his institutional map is incomplete. The book also benefits from giving another established viewpoint greater space.
Moving away from London again could have repeated the earlier pleasure of watching Peter misunderstand a rural situation. This time his greater experience changes the interest. He knows more about magic, institutions and negotiation, which makes it harder for him to assume that ignorance is the whole problem. The stronger question is how a capable investigator recognises where his competence has a geographical limit. A Scottish setting gives that uncertainty room to matter instead of serving only as a picturesque backdrop.
The book also has an established circle to draw on. A second perspective can ask different questions about the same unfamiliar place, and the story gains from allowing that difference to stand. It need not make one voice right and the other wrong to show that a London-centred map of power is incomplete. Practical observation remains as important as supernatural speculation: a body, a journey and local relationships all require attention. Peter's jokes still signal how he thinks, but they cannot settle a question of whose rules apply.
As the tenth main novel, this is an unfriendly place to start. The weight carried by familiar people and their training is earned elsewhere, particularly when another viewpoint gets space. Readers who prefer the compact London police cases may also find the broader geography less immediately satisfying. For a continuing reader, the expansion is purposeful. The series can take its investigative habits into unfamiliar terrain while admitting that those habits were shaped by a particular city. That tension gives a long-running world a way to remain curious rather than simply increasing the scale of its next threat.
How the audiobook sounds
The dual narration is a meaningful change rather than a decorative extra. Holdbrook-Smith preserves Peter’s familiar perspective, while Marks gives the additional viewpoint its own rhythm and authority. The contrast helps the larger cast and geographical shift feel intentional.
The two credited performers make the change of perspective immediately audible. Holdbrook-Smith retains Peter's familiar register; Marks has room to establish the other viewpoint on its own terms. This is useful for a story travelling away from the main series' London assumptions. The contrast is structural rather than a novelty: a listener can hear that the same place might be noticed differently depending on who is speaking.
The recording's shifts between voices reward a little continuity of listening. A commute can carry a scene, while a longer session makes the relationship between perspectives and the unfamiliar setting easier to hold. Neither performer needs to imitate the other's habits. Listen instead for how confidence, curiosity and uncertainty are expressed differently when established characters face local arrangements they cannot take for granted. If you strongly prefer a single first-person audio centre, the change may require adjustment. It gives the novel's geographic and social expansion a formal counterpart, and it helps the crowded later-series cast feel organised.
Can I start here?
Read Amongst Our Weapons first. What Abigail Did That Summer is useful additional background for Abigail, but not a numbered main novel.
Read Amongst Our Weapons first. What Abigail Did That Summer can add useful background for Abigail, though it is not a numbered main novel. If Foxglove Summer appealed because Peter had to work outside London, this revisits the challenge with a more experienced investigator and a broader circle. Readers who want only London streets and the Folly's familiar reach should expect a genuine change of setting. The dual-voice audiobook is particularly suitable if you enjoy contrasting viewpoints; a reader who prefers one consistent narrator can choose print.
