Lucy Foley Writes First New Miss Marple Mystery in Decades

When HarperCollins and Agatha Christie Limited tapped Lucy Foley to revive Agatha Christie's most beloved amateur sleuth, they handed her one of publishing's most coveted — and most daunting — commissions. As Marie Claire reports, Murder at the Grand Alpine Hotel, released September 22, 2026, marks the first fully authorized Miss Marple mystery written by another author, a milestone that has drawn readers back to Foley's own back catalogue, including her breakout thriller The Guest List.

The significance of the commission is hard to overstate. As Town & Country notes, this is the first authorized Marple mystery since 1976 — a nearly fifty-year gap that makes the handoff to a living novelist genuinely historic in the world of classic crime fiction.

Foley's selection was not arbitrary. According to Friends & Fiction, she has more than 10 million copies of her books in print worldwide, and The Guest List earned both a Reese's Book Club selection and the Goodreads Choice Award for Mystery & Thriller — credentials that signal the kind of commercial and critical reach Christie's estate would need behind such a high-profile continuation.

The Guest List, a locked-room thriller set on a remote Irish island during a wedding, established Foley as one of the leading voices in contemporary suspense — a writer fluent in the classic conventions of the genre Christie herself defined.

According to Goodreads, Foley was commissioned specifically by Agatha Christie Limited to write Murder at the Grand Alpine Hotel as the first authorized full-length Miss Marple continuation novel. The official Agatha Christie website describes Miss Marple's return in September 2026 as a brand-new novel from a New York Times bestselling author — lending the project the estate's full imprimatur.

Early critical reception has been warm but precise about what the book is and isn't. As the Indian Express puts it, the novel reads as 'more a Foley book than a Christie one' — but calls it 'a page-turner with hardly any dull moments' and recommends it for readers who enjoy gripping mysteries with a twist.

That framing matters for readers approaching the book with expectations calibrated to either author. NPR described the novel's opening — filled with gasps and exclamations in multiple languages — as carrying the feeling of a Christie novel while being unmistakably Foley's own work.

USA Today reported that the book was generating reader conversation even before its official release date, with strangers on public transit stopping each other to ask how it was — a small but telling indicator of genuine public curiosity around the project.

The commission also arrives at a moment when Foley's profile is expanding rapidly beyond the page. According to Marie Claire, four of her books are currently in screen adaptation, including The Paris Apartment, which has shifted from a film to a television production — making her one of the more cinematically sought-after crime writers working today.

Books of Brilliance described the novel as bringing Miss Marple "out of retirement" — a phrase that captures both the affection Christie fans carry for the character and the weight of expectation Foley agreed to carry when she accepted the commission.

Murder at the Grand Alpine Hotel is available now from HarperCollins; The Guest List remains available wherever books are sold.
