The Diamond Conspiracy

After escaping the clutches of Thomas Edison, Books and Braun eagerly anticipate a leisurely return home, but are swiftly pulled back into action when Braun receives an emergency signal. The Ministry Seven, Braun's team of streetwise child informants, is in serious danger, prompting the duo to rush back to England. Upon arrival, they discover the Ministry has been disavowed, and the sinister Department of Imperial Inconveniences aims to eliminate its agents, with the malicious Maestro and a treacherous doctor posing new threats to the very heart of society.
