Freelance detective Lin Mo was invited, carrying the shadow left by the unsolved case two years ago, trying to use logic to break the fog of the "curse". The cold and mysterious heir to the manor, the tight-lipped old housekeeper, the distant relative who covets the family property, the mysterious visitor with unknown purpose... Everyone has a secret, and everyone may be the murderer.
As the investigation deepens, the truth about Black Petals, dusty family secrets, and even Lin Mo's buried past gradually come to light. Underneath the conspiracy in the secret room, is it a man-made conspiracy or a continuation of the curse? When the clues intertwine into a web, the truth may be more chilling than the curse.
