At the junction of Sichuan and Yunnan, deep in the Yunling Mountains, there is a mountain platform called Yaping.
In the center of the platform, squats an old house from the Republic of China. With black tiles, white walls and green bricks on all sides, it looks like an upside-down coffin from a distance.
In the twelfth lunar month of 2004, a heavy snowstorm closed the mountain. Eleven people are trapped in a hotel converted from an old house, each with their own purposes and secrets.
Provincial capital detective Shen Jianshan returned to his hometown after seventeen years. He just wanted to escape the boredom of suspension investigation. However, on the first morning, he found the hotel owner Liu Yaoniang dead in the bedroom - the door was locked from the inside, the wooden bolt was inserted horizontally, the window was closed, and the window paper was intact. There were seven stab wounds on his body and the murder weapon disappeared.
Locked room murder.
The snow is still falling. The road is broken. The phone lines were downed. There is no cell phone signal.
In this isolated white Jedi, everyone may be a murderer. Everyone lies. What Shen Jianshan didn't know was that a hundred years of old blood still seeped through the cracks in the walls of this old house——
In 1937, salt merchant Luo Qiming died suddenly in his secret room.
In 1968, the housekeeper was taken away by the "four old" crowds and never came back.
In 1991, a waitress named Lin Xiuying died in a dry well in the backyard.
The signs of death vary, but they all fall in the twelfth lunar month.
Who is the murderer?
