This is a criminal investigation novel that revolves around the cooperation between forensic doctor Ling Chen and rookie detective Su Xiao. Ling Chen used precise forensic techniques to interpret the silent evidence on the corpse and the scene, while Su Xiao used criminal psychology to analyze the murderer's motives. From the embers of the fire to the old skeletons, from local murders to cross-city suspicions, the two combined "physical evidence" and "mental evidence" to decipher the truth in complex cases and the puzzle of human nature, interpreting their professional persistence of "speaking for the rights of the living and speaking for the dead."
