Katherine Reay, whose name has become synonymous with bookshop-centered fiction, launched her latest novel, The Undercover Bookshop, on October 6, 2026 — trading contemporary literary warmth for the shadowed corridors of Cold War espionage, as Writers Digest reports.
The novel is set in the English Cotswolds in 1950, where amateur sleuth Gemma Brown begins to suspect her neighbor may be a Soviet spy, according to The Nerd Daily's excerpt feature.
In a Writers Digest interview, Reay discussed the famous female Cold War spy who helped inspire the book — a detail that points to the same kind of meticulous historical research that has distinguished her fiction since her contemporary debut.
From The Printed Letter Bookshop to The Undercover Bookshop: Reay's Evolving Signature
Reay built her readership with contemporary novels including The Printed Letter Bookshop (2019), and her move into historical mystery fiction has been well-received, as the Salisbury Post notes.
The decision to anchor a spy thriller inside a bookshop is a characteristically Reay move: it sustains the thematic continuity her readers recognize while pushing the genre range of her work considerably further.
Her new release has earned her a place in People magazine's roundup of authors writing Agatha Christie-inspired mysteries — a notable signal of how the book is being positioned within the current Golden Age mystery revival.
Reay herself addressed that cultural moment directly, writing an essay for CrimeReads on October 6, 2026 — timed to her launch — on the enduring popularity of Golden Age British mysteries.
A Multi-City Launch Tour Anchored in Indie Bookshops and Libraries
The launch tour underlines Reay's close relationship with the independent bookshop community her fiction has long celebrated: Wheatgrass Books in Livingston, Montana, hosted an evening event on October 14, pairing the author with the kind of intimate, community-centered venue that echoes her novels' settings.
Library appearances rounded out the schedule: Rowan Public Library in Salisbury hosted a free event on October 9, and Carmel Clay Public Library featured Reay on October 12 as part of its Author Series.
Reay also made a stop in Spartanburg to promote the novel, as the Greenville Journal reported, suggesting a broad regional reach for the tour across the American South and Midwest.
The breadth of the launch — combining national media coverage in People, a CrimeReads essay, a Writers Digest interview, and stops at indie bookshops and public libraries — reflects the kind of layered, reader-facing campaign that has become essential for literary fiction authors working to build sustained audience relationships beyond the opening week.
The Undercover Bookshop is a Cold War historical mystery set in 1950 Cotswolds England, in which a bookshop sits at the center of an international intrigue — for readers who want to know how it stands alongside Reay's earlier work, the book is available now from major booksellers.
