The Gray Shadow A Mystery Story For Boys

"The Gray Shadow" by Roy J. Snell is an early 20th-century mystery where Johnny Thompson, a youthful, adventurous carnival worker, finds himself caught in a web of shady gambling operations, an air mail theft, and the puzzling Gray Shadow. The story kicks off at a lively carnival, where Johnny's search for excitement leads him to overhear whispers of a corrupt gambling ring and also see a con artist in action, pushing him to step in. By the time the carnival lights dim, Johnny has some marked money and a head full of questions, including a mysterious Gray Shadow, setting him on a path filled with suspense and peril.
