A lonely tower. A brutal murder. Secret passages, hidden identities, and an enemy who prefers to strike from the shadows. Hugh "Bulldog" Drummond expects little more than relaxation when he sets off on a golfing holiday with his friend Peter. Instead, an encounter with a terrified stranger draws them toward Temple Tower, an isolated house surrounded by mystery and danger. Something sinister is happening there, and Drummond has never been particularly good at walking away from trouble. Soon murder, concealed passages, mysterious visitors, and the masked figure known as Le Bossu Masqué plunge Drummond into a deadly puzzle stretching between England and France. Every discovery raises another question, and beneath the intrigue lies an opponent prepared to kill to keep the secrets of Temple Tower buried. Fast, atmospheric, and packed with the extravagant danger that made Bulldog Drummond famous, Temple Tower is the sixth novel in Sapper's celebrated series-a headlong mixture of mystery, adventure, menace, and old-fashioned pulp excitement.
