What The Devil Knows

More about the book

Sebastian St. Cyr believed a notorious serial killer was caught until a shocking wave of gruesome murders strikes London in this gripping historical mystery. It's October 1814, and with the war against France over, diplomats gather in Vienna to reshape Europe. However, London is gripped by a series of heinous murders reminiscent of the Ratcliffe Highway killings from three years prior, where two families were brutally murdered. A young seaman, John Williams, was arrested but hanged himself before trial, leading to a temporary sense of security. Now, with the lead investigator, Sir Edwin Pym, killed in a similar manner and others linked to the original case meeting violent ends, fear returns to the city. Bow Street magistrate Sir Henry Lovejoy seeks help from his friend, Viscount Devlin, as Pym's colleagues dismiss the deaths as coincidence. Yet, Sebastian's investigation into the past murders reveals that Williams may not have been the true killer. As he delves deeper, he must uncover the identity of the real murderer and their motive before more lives are lost.
