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. Meanwhile, Evaline has received some very disturbing news--news that will change her life forever. Along with that unpleasant knowledge is the strange disappearance of her nemesis, the disreputable pickpocket Pix. When it becomes clear the arch-villainess the Ankh has made her next move, it will take all of Mina's Holmesian ingenuity and Evaline's courage and determination to stop the criminal from executing her boldest and most dangerous plan yet!
