"It is not the wolves that should be feared but the sly foxes that lurk in their shadows."  A rogue Masked Master, the Fox, has returned to the kingdom of Shanhe. The assassin's arrival triggers chaos, entangling the lives of a maid, bodyguard and nobleman.  For Bai Mingzhu, it could jeopardise her secret mission.  For Liu Disung, it reminds him about the vow to avenge his father's murder. For Wang Joaolong, it reveals Shanhe's darkest truths. The only certainty is that Shanhe will never be the same.
