The Oxford Trophy Murder

Oxford, 1920. One body. Three impossible clues. And a woman mathematician who will not accept “accident” as an answer.

Women can study at Oxford, but they still cannot earn degrees. With a historic vote on women’s degrees approaching and the city caught up in the spectacle of Eights Week, Oxford’s annual rowing races, the last thing the university needs is a scandal.

Then the Duke of Calverley—a powerful patron of the university and outspoken opponent of women’s education—is found dead in a locked boathouse.

Oxford is quick to call it a tragic accident. Celia Wren, a brilliant mathematics student at Somerville College, knows the facts do not hold. The wound tells the wrong story. The locked room should have been impossible. And the gap in the timeline does not add up.

Using logic, structure, and an eye for the details powerful men overlook, Celia begins her own investigation. But in a world where women are excluded from power, truth is dangerous—and exposing a murderer may threaten the very future Celia is fighting for. As she follows the clues through college rivalries, hidden financial crimes, institutional secrecy, and a convenient occult rumour designed to blame the wrong person, she uncovers a crime someone has constructed with devastating care.

A meticulously plotted historical mystery set in 1920s Oxford, featuring a brilliant female sleuth, a locked-room puzzle, and the high-stakes fight for women’s place in a university determined to keep them out. Perfect for fans of classic mysteries, brilliant women, atmospheric 1920s Oxford, and fair-play puzzles where every clue is in plain sight—if you know how to look.
