In the first year of Tianshou, during the first snowfall in the divine capital, an old minister died in a locked study. The back of the mirror was engraved with "Li Tang is immortal". There were no stab wounds on the body, but a Ningxin Pill rolled down at the foot of the bed. The second deceased person fell in a secret room guarded by six policemen - the murderer did not enter the door, and the murderous things may have been delivered to the home.
Luozhou Sima Di Renjie was ordered to investigate the case. Together with Shen Ruyan, who understands medical science and corpse appearance, bodyguard Pei Dongqing, and Yuan Zhiwei, who is good at checking old files, they traced a box of medicine to a list of former officials who could be written as rebels. In the next ten years, the Silk Road Camp, Luo Zhi Prison and the Crown Prince's turmoil followed one after another: each case has evidence that can be reviewed, but there may not be the entire truth that can be disclosed.
When the power can first convict and then force evidence to testify, is solving the case just about catching the murderer? Di Renjie wrote the names that could not be entered into the official records into the "Book of the Dead", and again and again made imperfect choices between the truth, the law and the young dead.
