Combining the super-sensory ability of "evidence synaesthesia" with the character of "modern strong woman in the workplace", the story unfolded in Shanghai during the Republic of China. Each case is no longer a simple supernatural event, but through "personal accounts of physical evidence" to complete the chain of evidence in the criminal investigation process, and then solve the perfect crime. The core anti-routine of this book is that the heroine's ability makes her a genius on the supernatural side, but it is also a nightmare on the human side - she cannot turn off her listening to physical evidence, is tortured by hundreds of "voices" every day, and is on the verge of mental collapse.
