Thomas Pitt is summoned to Buckingham Palace after a prostitute is murdered during a private gathering of politicians and businessmen discussing an African railway project. The guests are confined inside the palace, but rank and royal protocol make ordinary interrogation almost impossible.
Working with palace servants and Special Branch, Pitt reconstructs the victim’s movements and the interests represented at the meeting. The case exposes the collision between imperial finance, sexual exploitation and the determination of powerful men to keep scandal away from the monarchy.
