When seven schoolgirls earn a remarkable reward a cottage on a quiet lake for their hard work they expect a peaceful summer. Instead, they find mystery. Jean Gordon and her friends, the Stealthy Prowlers, aren't content to simply laze away the days. Their loyalty to each other and their shared hunger for adventure draws them into a puzzle involving a poor orphan girl living nearby. What begins as an escape from the boys' secret society becomes something far more serious: a test of what girls can accomplish when they trust their instincts and each other. The S. P. Mystery captures that specific childhood thrill of a secret club, a hidden headquarters, and the electric belief that real danger and real purpose await just beyond the ordinary world. It's a time capsule of 1930s girls' adventure fiction, but its heart is timeless.
