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 five-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?

The second mystery was a featured “summer reading” book at the Jewish Daily Forward because it deals with the “mazikeen,” which are half-human and half-angel beings from Jewish folklore. Both of the mysteries so far in the series have Poetic (as in Edgar Allan Poe) style and supernatural elements that readers enjoy.
