The Case of the Missing Tiger

A Thrilling Adventure from the Castlen Cousins Detective Agency

A stolen tiger. A hidden tunnel. Seven young detectives with nothing to lose. When a rare albino tiger named Ghost disappears from the zoo, the Castlen Cousins know this is no ordinary mystery.

Bound by family and determined to stay together after a life-changing tragedy, Claire, Liam, Ayla, Mary Sue, Rebecca, Evelyn, and little Pepita turn their childhood game into a real detective agency. What begins as curiosity quickly becomes a dangerous investigation filled with secrets, hidden meetings, and unexpected risks.

With courage, teamwork, and imagination, the cousins must uncover the truth before it’s too late—for Ghost, and for themselves. This heartwarming and suspenseful story proves that even the youngest voices can solve the biggest mysteries.

“The children supplied the imagination. We simply captured it.”
