A car crash in broad daylight is the brief opening to this sweeping mystery.
Policewoman Pei Zhiyi is calm and capable, an elite officer; rookie Chi Qinghe is warm and perceptive, with an animal-like instinct. The cool-headed one and the fiery one are ordered to investigate the case, but the stench drifting from near the crash site leads them to uncover just a sliver of a vast criminal enterprise.
Yet the case takes a turn far beyond anyone’s imagination. Human fat discovered in gutter oil is like a boulder dropped into still waters. Beneath its ripples, a murder case that has lain dormant for years, suspicions of cannibalism that challenge the limits of human nature, and a brutal school-bullying case buried by time all rise to the surface.
Pei Zhiyi is like the cold light of reason, while Chi Qinghe is like a warm flame of feeling. As they struggle against the odds in pursuit of the truth, they complement each other perfectly. Chi Qinghe always spots the details Pei Zhiyi misses, while Pei Zhiyi gives Chi Qinghe’s instincts a rational foundation. They are each other’s eyes in the darkness, and the most dependable partners in the line of fire.
When all the clues finally loop back to the beginning in a strange twist, they must uncover the saddest truth and most desperate revenge behind the car crash.
This is an intellectual race against a perfect criminal, and a duet of hope sounding out in humanity’s darkest depths.
