Ever since the debacle of the Chess Queen Enigma, Mina Holmes and Evaline Stoker have laid low, trying to settle back into their quiet lives as young ladies of London. But the Holmesian deductive abilities won't remain dormant for long, and when Mina receives a strange package from a winged, midnight visitor, she is catapulted into a new, dangerous adventure: the search for The Carnelian Crow.
