Unhappy wife and young mother Penelope Wolfe fears scandal for her family and worse. A Tory newspaper editor has been stabbed while writing a reply to the latest round of letters penned by the firebrand Collatinus. Twenty years before, her father, the radical Eustace Sandford, also wrote as Collatinus before he fled London just ahead of accusations of treason and murder --a mysterious beauty closely connected to Sandford and known only as N.D. had been brutally slain. Now the seditious new Collatinus letters that attack the Prince Regent in the press seek to avenge N.D.'s death and unmask her murderer. What did the dead editor know that provoked his death? Her artist husband Jeremy being no reliable ally, Penelope turns anew to lawyer Edward Buckler and Bow Street Runner John Chase. As she battles public notoriety, Buckler and Chase put their careers at risk to stand behind her and find N.D.'s killer. They pursue various lines of inquiry including a missing memoir, Royal scandal, and the dead editor's secretive, reclusive wife. As they navigate the dark underbelly of 1813 London among a cast driven by dirty politics and dark passions, as well as by decency and a desire for justice, past secrets and present criminals are exposed, upending Penelope's life and the lives of others.
