In post Civil War New York City, Detective Pat O'Malley is living inside Poe's Cottage in the Bronx. O'Malley is haunted by Poe one night, and the detective finds a strange note. As a result, O'Malley decides to prove that Edgar Allan Poe did not die in Baltimore from an alcoholic binge but was, instead, murdered. O'Malley quickly becomes embroiled in a "cold case" that thrusts him into the lair of one of the most sinister and ruthless killers in 1865 New York City.
