Against the vividly drawn backdrop of Victorian London, amateur sleuth Charles Lenox must unlock a mystery concealed in the architecture of the city itself, in this new novel from acclaimed author Charles Finch.
It's 1879, and Lenox is convalescing from the violent events of his last investigation. But a desperate letter from an old servant forces him to pick up the trail of a cold case: the murder of an apothecary seven years before, whose only clue is an odd emblem carved into the doorway of the building where the man was killed. When Lenox finds a similar mark at the site of another murder, he begins to piece together a hidden pattern which leads him into the corridors of Parliament, the slums of East London, and ultimately the very heart of the British upper class.
