The Mechanical Grave.

The year is 1895. Steam-powered ships fly through the air. Clockwork robots have replaced servants. And a grisly murder has taken place in the dark night of New York City. Called to the scene of the ritualistic murder of a young woman, newly appointed police commissioner Teddy Roosevelt discovers Detective Wayne and his police officers power usurped by two special investigators appointed by the White House: Occultist Edgar Allan Poe, a clockwork automaton housing the soul of the literary legend, and Mrs. Emma Entwistle, a dangerous assassin with a unique connection to the otherworld. When they illicit information from the demon Neshrew, a much darker and more dangerous plot of world domination is uncovered.
