Rome prepares for Domitian's double triumph over the Chatti and Dacians when an official supervising the celebration falls from the Capitoline Hill. Albia doubts that the death was accidental because the victim's abusive conduct and commercial schemes had created numerous enemies.
Her inquiry moves through triumphal workshops, musicians, animal handlers and suppliers of imperial purple. A second death at the Tarpeian Rock confirms that a killer is using the confusion of the state ceremony to settle private grievances.
