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.

It's 1866 in New York City. Civil War Vet and Detective Pat O'Malley's biggest case returns him to the deep, dark South to search for the kidnapped wealthiest inventor and entrepreneur in America. But the widening gyre of anti-Semitism and racism pulls him down into the pit of hell itself. Disguised as an Oxford England Professor, O'Malley infiltrates the anti-Semites' group and travels with his partners, Becky Charming and his father, Robert, down to a Collierville, Tennessee mansion. At the crux of this case are a Jewish father and his eight-year-old son, Seth. They have developed a unique bond that relies on Jewish folklore and a belief that they are Mazikeen, half-angel and half-human, born from the loins of Adam's strange female cohorts during the 130 years he was banished from the Garden. Will O'Malley find Dr. Mergenthaler before it's too late? What does this world-wide eugenics group have planned for the mongrel races? Read Jim Musgrave's Disappearance at Mount Sinai, the second mystery in the series of Pat O'Malley Mini-Mysteries.

This third mystery plunges O'Malley into the Steampunk world of Jane the Grabber. The first two mysteries have served as introductions to a mysterious new paradigm. Jim Musgrave has begun a genre of fiction called Historical Steampunk Mystery. Taken in their entirety, these three novels show the progression of Pat O'Malley from common citizen into a sleuth who must confront a time-traveling group that poses a world-wide threat....
