The British Library has just announced something pretty exciting: in October 2026, it’s opening a major exhibition dedicated to the Queen of Crime herself, Agatha Christie.

The timing is especially meaningful—it marks 50 years since her death, making it the perfect moment to reflect on her life, her work, and the legacy she left behind.

This won’t just be about her famous books like Murder on the Orient Express or the iconic detectives Hercule Poirot and Miss Marple. The exhibition is designed to pull back the curtain on Christie’s world—her travels, her fascination with archaeology and pharmacology, and the real-life influences that shaped her timeless mysteries.

Visitors will get to see some incredible personal items, many of which have never been shown publicly before. Think Christie’s own typewriter (the very one she used to write And Then There Were None), family photos from her adventures in Egypt and Hawaii, her teenage notebooks, and even letters she wrote to her loved ones—including one to her husband describing a trip on the Orient Express, which later inspired one of her most famous novels. You’ll even be able to hear Christie’s voice through recordings she made on her dictaphone.

The exhibition also happens to line up with two other milestones: 100 years since the publication of The Murder of Roger Ackroyd—the novel that truly cemented Poirot’s reputation—and 50 years since Miss Marple’s swan song in Sleeping Murder. Together, these anniversaries make 2026 a huge year for Christie fans.

Beyond the British Library, libraries across the UK will host events, displays, and celebrations of Christie’s influence on crime fiction, showing just how deeply her work continues to resonate.

So whether you’re a lifelong Christie fan or someone just dipping into her mysteries for the first time, this exhibition promises a rare, behind-the-scenes look at the woman who forever changed crime writing. Photo by National Portrait Gallery, London, Wikimedia commons.
