Marc de Segur goes to the County of Lorme, granted to him by the king. His new castle is located among forests and mountains, far from big roads and cities, and Mark expects his stay there to be calm and even boring. However, he is soon joined by the nine-tailed werewolf fox Lee Jin Ho, who dreams of taking a break from social life in the capital and his role as the patriarch of the fox tribe, which means that the owner of the castle will definitely not be bored. In addition, tragic and ominous events begin to occur in the castle: the maids die one after another, and then Mark himself becomes the target of an unknown villain. He again has to take up the investigation in order to restore order in his possessions, and the help of the thousand-year-old fox is not at all superfluous in this matter.
