Set in the snowy heart of Regency London, The Adventures of Sarah Cavendish: The Glasshouse Mystery invites readers into a world of grand townhouses, hidden tunnels, glowing glasshouses, and secrets waiting to be uncovered. Ten-year-old Sarah Cavendish has always been far too curious for polite society. While other young ladies are expected to concern themselves with posture, embroidery, and proper manners, Sarah would much rather explore the world around her, ask dangerous questions, and solve mysteries no one else seems to notice. But when strawberries begin mysteriously disappearing from her father's magnificent glasshouse in the middle of winter, Sarah finds herself drawn into an adventure far greater than she imagined. Together with Tom Finch, a clever street boy surviving alone among the frozen alleys of London, Sarah begins investigating the strange thefts hidden beneath the warm glass walls of Cavendish House. Soon they uncover secret tunnels, hidden footprints, midnight intrusions, and clues that suggest someone-or something-is entering the glasshouse after dark. Yet as the mystery deepens, Sarah begins discovering another world beyond the comfort of her own privileged life. Outside the warmth of Cavendish Square, winter is not magical for everyone.
