I've been on a kick with these rediscovered classic series for girls, and Amy D. V. Chalmers' Madge Morton's Secret was a total delight. It's the fourth book about Madge and her friends, but you can jump right in. First published in 1909, it has that wonderful old-fashioned adventure feel without being stuffy.

The Story

Madge Morton, her cousin Phil, and their friends Nellie and Jean are spending their summer living on a houseboat, the Merry Maid. They're all set for swimming, picnics, and general fun. Their peace is shattered when a nervous, secretive young woman named Miss Betsey comes aboard with a cryptic warning for Madge. Soon after, strange events follow: their boat is searched, a suspicious man is seen lurking, and it becomes clear someone is desperately trying to get something they believe is hidden on the Merry Maid. Madge finds herself guarding a secret that could affect someone else's future, forcing her and her "houseboat girls" to become amateur detectives to protect their floating home and uncover the truth.

Why You Should Read It

What charmed me most wasn't just the mystery—which is engaging and well-paced—but the sheer joy of the friendship. These girls are resourceful, loyal, and wonderfully supportive of each other. They solve problems as a team. Madge is a great heroine: kind, brave, and principled. The houseboat setting is a character itself, making the adventure feel cozy and unique. It's a story about integrity and standing by your friends when things get tough. In a modern world, there's something refreshing about a clever, low-tech mystery solved by observation, courage, and teamwork.

Final Verdict

This book is perfect for anyone who loves classic series like Nancy Drew or The Boxcar Children, but is looking for a strong focus on friendship. It's also a great pick for younger readers (or the young at heart) who enjoy historical settings. You get a fun mystery, a wonderful sense of time and place, and a group of friends you'll wish you could join on their next adventure. A genuinely uplifting and entertaining read.
