About This Book
A resourceful young inventor investigates a conspiracy to steal and hide mechanical inventions, following clues from a heavy locked chest through a series of narrow escapes and discoveries. The plot moves episodically through rooftop crashes, secret listeners, messages, subterranean traps, and daring rescues as the protagonist and his allies piece together evidence, pursue suspects, and recover contraptions. Recurrent themes of secrecy, mechanical ingenuity, and loyalty underpin a gadget-driven narrative that culminates in the exposure of the thieves and the securing of the inventor’s technological secrets in a reinforced vault.
