Gilly Macmillan trades her usual domestic suspense territory for the shadowy corridors of dark academia in The Burning Library, a thriller that weaves together medieval manuscripts, secret societies, and ruthless ambition against the atmospheric backdrop of St Andrews, Scotland, and the ancient streets of Verona. The result is an ambitious literary puzzle that captivates as much as it occasionally overwhelms, earning its place among the more intellectually engaging thrillers of recent years while stumbling under the weight of its own complexity.
The novel opens with a striking image: Eleanor Bruton’s body discovered on a remote Scottish island, clutching secrets that will unravel a centuries-old conspiracy. This middle-aged woman who spent her days arranging flowers and plumping church cushions harbored a dangerous obsession with a fragment of medieval embroidery—a seemingly worthless scrap of fabric that two rival organizations of women have spent over a century killing to possess.
The Scholar at the Center of the Storm
Dr. Anya Brown becomes Macmillan’s most intellectually formidable protagonist to date. A brilliant young scholar blessed—or perhaps cursed—with an eidetic memory, Anya has just achieved international recognition for translating the cryptic Folio 9 manuscript. Her exceptional ability to recall visual details with perfect clarity makes her uniquely qualified for the work that Diana Cornish, a charismatic professor at St Andrews’ exclusive Institute of Manuscript Studies, desperately needs her to perform.
What Macmillan does exceptionally well here is portraying Anya’s internal conflict. The character never simply relies on her photographic memory as a convenient plot device; instead, the author explores how this gift isolates her, creates imposter syndrome, and complicates her relationships. Anya’s vulnerability—particularly regarding her seriously ill mother and her relationship with boyfriend Sid—adds necessary humanity to what could have been a one-dimensional genius character. Her determination to leverage her discoveries to protect those she loves drives the narrative’s emotional core, even as the intellectual puzzle-solving propels the plot forward.
A Web of Women’s Warfare
The novel’s most provocative element lies in its depiction of two secret societies locked in ideological warfare. The Order of St. Katherine believes women must exercise power from the shadows, pulling strings behind the scenes, embracing traditional roles while secretly controlling outcomes. The Fellowship of the Larks fights to place women in overt positions of power, though their methods remain hidden. Both organizations claim to champion women’s advancement; both will kill to achieve their goals.
Macmillan deserves credit for refusing to paint either group as purely heroic or villainous. The moral ambiguity feels genuine and uncomfortable in the best way. Diana Cornish, brilliant and passionate about helping women, nevertheless manipulates Anya ruthlessly and maintains an affair with a married judge to influence legislation. These women operate in shades of grey that force readers to question whether the ends justify increasingly violent means.
However, this central conflict occasionally feels more theoretical than visceral. While individual scenes crackle with tension, the broader ideological battle between the two groups sometimes reads as contrived, with their century-long rivalry feeling more like a convenient thriller framework than an organic historical development.
The Voynich Manuscript Mystery
The real treasure at the heart of The Burning Library is the legendary Voynich manuscript—a real-world medieval text that has baffled scholars for centuries with its indecipherable script and mysterious illustrations. Macmillan’s fictional solution to this historical enigma proves genuinely creative: the manuscript was created by five educated women from 15th-century Verona, encoding the location of an even more valuable text called The Book of Wonder.
The author clearly conducted extensive research, and her passion for manuscripts, medieval history, and the art of translation shines through. The sections where Anya pieces together clues hidden in embroidery fragments, heraldic symbols, and cryptic Latin poetry showcase Macmillan’s ability to make intellectual detective work as thrilling as a car chase. The journey to Verona, where Anya races to decode references to churches, frescoes, and the Nogarola family’s country villa, succeeds in making historical scholarship feel urgent and vital.
Detective Work and Dual Narratives
Running parallel to Anya’s academic quest is Detective Clio Spicer’s investigation into Eleanor Bruton’s death. Clio provides a grounded, procedural perspective that helps anchor the novel’s more fantastical elements. Her determination to uncover the truth about her mentor’s suspicious death adds weight to the stakes, reminding readers that real people are dying for these manuscripts.
The multiple perspective structure generally serves the story well, though Macmillan occasionally struggles with pacing. The frequent shifts between Anya, Clio, Diana, and various members of the rival organizations can feel choppy, particularly in the middle section where the plot juggles surveillance, academic research, ancient letters, and shadowy organizational machinations simultaneously.
Atmospheric Settings and Prose
Macmillan’s evocative prose brings both St Andrews and Verona to vivid life. The descriptions of Scotland’s windswept coastline, remote islands, and the medieval university town create a appropriately gothic atmosphere for this dark academic tale. The Verona sequences, where Anya traces connections between the Voynich manuscript and actual frescoes, churches, and architectural details, blend historical richness with thriller urgency effectively.
The author’s style has matured considerably since her earlier domestic thrillers like What She Knew and The Nanny. While those books excelled at claustrophobic psychological tension, The Burning Library demonstrates her ability to work on a larger canvas, incorporating historical research, international settings, and more complex thematic concerns.
Where the Novel Stumbles
Despite its considerable strengths, the book occasionally groans under the weight of its own ambition. The plot grows unwieldy as it attempts to juggle:
- The mystery of Eleanor Bruton’s death
- Anya’s translation work and family complications
- The rivalry between two secret societies
- Diana Cornish’s manipulation and eventual murder
- The hunt for The Book of Wonder
- Multiple subplots involving surveillance, academic politics, and hidden manuscripts
Some readers may find themselves wishing for a more streamlined narrative that fully explores fewer elements rather than superficially addressing many. The resolution, while providing answers, feels somewhat rushed given the elaborate setup, and certain character arcs—particularly Sid’s cyber-security expertise—don’t receive the development they deserve.
Themes Worth Pondering
At its core, The Burning Library asks difficult questions about women’s advancement and the cost of power. Must women compromise their ethics to succeed in systems designed by men? Can secret organizations claiming to help women be trusted when they employ manipulation, surveillance, and murder? The novel refuses to provide easy answers, leaving readers to grapple with these moral complexities long after the final page.
The book also examines how knowledge itself can be both power and curse, how history preserves some voices while silencing others, and how women’s intellectual contributions have been systematically erased or attributed to men throughout history.
Final Verdict
The Burning Library represents Gilly Macmillan’s most ambitious work to date—a sprawling, intellectually engaging thriller that mostly succeeds in its aims despite occasional structural wobbles. Readers who enjoyed academic mysteries like The Shadow of the Wind or the historical intrigue of Kate Mosse’s Languedoc trilogy will find much to appreciate here. Those seeking the tight psychological suspense of Macmillan’s earlier novels like The Perfect Girl or The Long Weekend may find this more diffuse and cerebral than expected.
The novel rewards patient readers willing to invest in its complex mythology and trust that the scattered pieces will eventually coalesce. While not flawless, it demonstrates a thriller writer expanding her range and tackling weightier themes without sacrificing entertainment value. For anyone fascinated by medieval manuscripts, the mysteries of the Voynich, or the shadowy ways women have sought power throughout history, this literary treasure hunt offers a compelling, if imperfect, journey.
