Let's set the scene. It's the early 1900s in San Francisco, a city of new money and old rivalries. Wealthy patriarch Cyrus Packard is found dead in his study. The door was locked from the inside. There are no wounds, no signs of a struggle. The only clue? A glossy, red apple clutched in his hand.

The Story

Enter John Knox, a principled and clever lawyer. He's hired to navigate the explosive fallout. Packard's will is a bombshell, disinheriting his scheming nephew and leaving his fortune in a trust. The nephew is the obvious suspect, but the 'how' is the real puzzle. How do you kill a man in a locked room with just a piece of fruit? Knox has to untangle a web of family bitterness, shady business deals, and suspicious servants. The investigation leads him from grand mansions to the city's bustling wharves, chasing a truth that seems to change with every new witness. The tension builds not with car chases, but with whispered conversations, hidden documents, and the growing certainty that the apple is more than just a prop—it's the key to everything.

Why You Should Read It

I adored this book for its brainy charm. This isn't a bloody thriller; it's a purely intellectual game. Walcott plays completely fair with the reader—all the clues are there. Trying to solve the 'locked room' before Knox did was my favorite part. Beyond the puzzle, the setting is a character itself. You can almost smell the sea air and hear the cable cars. John Knox is a great guide: he's smart but not infallible, and his dry sense of humor in the face of greed and melodrama is perfect. The book is really about the poison of family conflict—the 'discord' of the title—and how it can twist people. The solution, when it comes, is satisfyingly clever and oddly plausible, which is the highest praise for a mystery like this.

Final Verdict

This book is a treat for anyone who loves the classics of mystery's Golden Age. If you enjoy the puzzle-box plots of Agatha Christie or the clean logic of Sherlock Holmes, you'll feel right at home here. It's also perfect for readers who enjoy historical fiction that doesn't feel like a history lesson, but simply drops you into another time. The pace is steady and the prose is clear, making it a wonderfully absorbing weekend read. Don't let its 1905 publication date fool you—'The Apple of Discord' is a sharp, entertaining mystery that holds up brilliantly.
