"Voice memory" is the last corpse language. The protagonist can "hear" the dying sounds remaining in the bones of the deceased, thereby uncovering the truth.
In the Forensic Medicine Center of the Municipal Bureau, an unidentified skeleton lies on the autopsy table. The new criminal investigation captain Lin Yue insisted that the death was an accidental fall and urged the case to be closed as soon as possible. Chen Wen put on his gloves in silence.

He raised his head, looked over Lin Yue's shoulder with his empty gaze, and said softly: "No, this is homicide. She was looking for her red shoes."
