"Cambridge, 1933, All Hollows' Eve. After being called to a country estate to ease the stomach troubles of a housekeeper, Dr. Adelaide Hartest bears witness to a stranger's final moments inside the All Hallows Church. Despite the dagger plunged into his chest, it is ruled a suicide. In order to solve these two deaths, which have occurred not only hours, but mere miles apart, Commissioner Joe Sandilands must uncover the truth before the Hellfire Club--an elite society of intelligentsia and aristocrats--topples the institutions and harms the people he has sworn to protect, especially one that he has truly come to love."
