Natalie Sumner Lincoln's The Trevor Case is a classic mystery that proves a good puzzle never gets old. First published in 1912, it has all the charm of a drawing-room whodunit but with a heroine who's far more proactive than you might expect.

The Story

The story begins with the sudden death of Richard Trevor, a pillar of his community. The official verdict is natural causes, but his niece, Barbara Trevor, senses something is terribly wrong. Against the wishes of her family and the skepticism of the police, Barbara insists it was murder. Her only evidence is a small, curious detail she discovered at the scene—a clue everyone else has overlooked. Defying convention, she launches her own investigation, questioning family, servants, and business associates. As she digs deeper, she uncovers hidden tensions, financial troubles, and old grudges within the Trevor household. Barbara's search for the truth turns her from a grieving relative into a target, forcing her to outthink a clever killer before she becomes the next victim.

Why You Should Read It

What makes this book so enjoyable is Barbara herself. For a novel written over a century ago, she's a refreshingly capable and bold protagonist. She doesn't wait for a man to solve the mystery; she rolls up her sleeves and gets to work, using her intelligence and knowledge of the family to guide her. The plot is a tightly constructed puzzle. Lincoln plays fair with the reader, scattering clues and red herrings throughout the genteel setting. You get the fun of trying to piece it together alongside Barbara. It's also a fascinating window into the social world of the early 1900s—the manners, the class distinctions, and the limited options for women, which makes Barbara's actions even more notable.

Final Verdict

The Trevor Case is perfect for anyone who loves traditional mysteries in the style of Agatha Christie's early work or Anna Katharine Green. It's a must-try for fans of historical mysteries who enjoy a pre-war setting. If you're new to mysteries from this era, this is a great place to start—it's straightforward, engaging, and features a heroine you can't help but cheer for. Just be prepared to clear your evening; it's the kind of book that makes you say, 'Just one more chapter,' until you've reached the final, satisfying reveal.
