First published in 1919, Raspberry Jam is a golden-age mystery that locks you in a room with a puzzle. Sanford Embury is a rich, difficult man. His much younger wife, Eunice, and his live-in aunt, Miss Ames, don't exactly mourn him when he's found dead one morning. The doctor declares it heart failure, but everyone's suspicions are raised when it's revealed he ate poisoned raspberry jam before bed. Eunice prepared the tray herself.

The Story

The case seems simple: Eunice had motive and opportunity. But her friend, the sensible Agnes Blake, believes in her innocence and brings in the famous detective Fleming Stone. The real head-scratcher is the scene of the crime. Embury's bedroom door was locked and bolted from the inside, and the windows were securely fastened. No secret passages. So, if Eunice left the room and locked the door behind her, how did the poison get into the jam after she left? Or did she somehow administer it from outside a locked room? The investigation twists through family secrets, financial motives, and a cast of suspicious characters, all while grappling with that central, impossible question.

Why You Should Read It

I have a soft spot for these old-fashioned puzzles. Wells doesn't waste time. She sets up the mystery efficiently and lets the sheer audacity of the locked-room scenario drive the story. It's less about gritty procedure and more about logical deduction—the kind of book where you might pause and think, 'Wait, but what if...?' While the social attitudes are definitely of its time, the core plot is timeless. Fleming Stone is a calm, cerebral detective, and the joy is in watching him sift through the red herrings and alibis. The solution, when it comes, is satisfying in its cleverness. It's a reminder of why the locked-room mystery became such a beloved subgenre.

Final Verdict

This book is perfect for fans of Agatha Christie's Hercule Poirot puzzles or anyone who enjoys a mystery that plays fair with the reader. It's a short, focused novel ideal for a rainy afternoon. If you're new to early 20th-century mysteries, this is a great, accessible place to start. Just be prepared to look at your breakfast jam a little differently the next morning.
