The Shadow Sleuths A Detective Thriller Novel by Sibin Silvy Four brilliant kids. One stolen diamond. A trail of secrets that runs deeper than anyone imagined. When the priceless Blackwood Diamond vanishes from the Oakridge City Museum without a trace, panic spreads across the town. No broken locks. No alarms tripped. Only a black feather left behind. But while the adults search for answers in all the wrong places, four young friends—Alex, Sierra, Jayden, and Lena—see something others don't. Alex, the analyst, sees patterns no one else can. Sierra, the infiltrator, moves like a ghost through locked doors and coded puzzles. Jayden, the techie, turns gadgets into secret weapons. Lena, the empath, reads people like books—and remembers everything. Together, they are The Shadow Sleuths—a team built on trust, skill, and an unshakable bond. As their investigation deepens, the mystery turns darker. Hidden tunnels, encrypted footage, double-crosses, and a conspiracy that could rock the entire city. What begins as a jewel heist becomes a race to uncover the truth—before the shadows catch up to them. Perfect for readers aged 9–14 who love suspense, teamwork, clever twists, and heart-pounding adventure. If you enjoy Nancy Drew, Hardy Boys, City Spies, or Stranger Things, this thrilling debut will keep you guessing until the very last page.
