The horrifying rape and apparent suicide of Catherine Quixwood, wife of a wealthy merchant banker, falls outside the jurisdiction of new Special Branch head Thomas Pitt, but so pervasively offensive are the rumors about the victim that Pitt quietly takes a hand in the investigation. Yet even with the help of his ingenious wife, Charlotte, and his former superior, Victor Narraway, Pitt is stumped. Why did high-minded, cultured Catherine choose not to accompany her husband to a grand party on the night of her demise? Why did she dismiss all her servants for the evening and leave the front door unlocked? What had been her relationship with the young man seen frequently by her side at concerts and art exhibits? And what can be done to avenge another terrible crime: the assault on Angeles Castelbranco, beloved teenage daughter of the Portuguese ambassador? As an ordinary policeman, Pitt used to enter London’s grand houses through the kitchen door. Now, as a guest in those same houses, can he find the steel in his soul to challenge the great men of the world with their crimes? The path to the truth takes him in deeply troubling directions, from the lofty world of international politics and finance to his own happy home, where his own teenage daughter, Jemima, is coming of age in a culture rife with hidden dangers.
