Autumn, twenty-three years of the Republic of China.
The rain in the south of the Yangtze River lingered for a whole month, soaking the city of Gusu until it became damp. The bluestone road was washed by the rain and shone brightly, reflecting the white walls and black tiles on both sides. Occasionally, a awning boat rocked across the water, breaking up the dense mist in the river.
The Gu family's old house in the west of the city is hidden in the deepest alley, like a giant beast that has been dormant for hundreds of years, silently breathing the moist wind. The door of the old house is made of heavy rosewood, with a copper door knocker nailed on it. It is kept closed all year round. Only the faded "Growing and Reading Heirloom" plaque on the lintel reveals an indescribable gloominess in the rain and fog.
No one knows what is hidden in the old house of the Gu family. They only know that three years ago, the master of the Gu family, Gu Mingshan, died suddenly and strangely overnight. His eyes were wide open, his orifices were bleeding, and his fingertips were digging into the ground, as if he saw something extremely terrifying before he died. The government investigated for several months and finally closed the case hastily as "died of sudden illness." From then on, the Gu family's old residence became a haunted house that everyone in Gusu City avoided.
But I, Shen Yan, a down-and-out detective from Peiping, opened the dusty door of the Gu family's old house on this rainy autumn day.
I came here just to find my missing sister - Shen Qinghuan.
