the Sentinel Club: Case of Missing Baseball Cards

In the summer of 1986, in the quiet town of Maplewood, Indiana, four friends form a secret club in their treehouse headquarters and call themselves The Sentinel Club. When Marcus discovers his treasured baseball card collection has mysteriously disappeared, the newly formed club launches their very first investigation. Joined by their lovable Golden Retriever, Boomer, the kids ride their bikes through the neighborhood, follow suspicious footprints, set up stakeouts, and explore creepy places like the old abandoned rail yard. What starts as a simple missing-items case quickly turns into something much bigger. As clues pile up, the kids discover that someone older is manipulating younger children into stealing - using their problems and dreams against them. With notebooks, flashlights, prayers for courage, and unbreakable friendship, The Sentinel Club must solve their first real mystery before another family loses something precious. Filled with bike chases, hilarious schemes, treehouse meetings, and heartfelt moments, this wholesome 1980s adventure celebrates courage, teamwork, doing the right thing, and trusting God even when things get scary. Perfect for fans of The Goonies, Scooby-Doo, and classic children's mysteries. The Sentinel Club - Where ordinary kids do extraordinary things... one mystery at a time.
