Though she is a child of the night, Pa has warned her to stay away from the deep parts of the forest as there is an evil that lurks there.  Serafina is stealth in her maneuvers around the Biltmore Estate. People do not notice her and she has a skill of making herself almost invisible. But Serafina notices things, and when children start disappearing she knows it is the man with the black cape.  But which man?  There are several men visiting the Biltmore Estate.  Serafina, the CRC, sets out to catch a very dangerous rat! And, yes, she will have to venture into the forbidden forest to catch the man with the black cloak.
