Twelve years ago, a disappearance case became an unsolved mystery. Twelve years later, a similar case reappeared. Next to each body is a hand-drawn sketch of a skull—disturbingly accurate.
Wei Jingyan, the leader of the serious crime team of the Municipal Criminal Investigation Detachment, is good at analyzing people's hearts in detail; Shen Yebai, the deputy team leader, has a cold face and a vicious tongue but can understand the smallest traces. The two teamed up to chase the murderer, but found that the style of those sketches was surprisingly similar to their mutual friend, freelance illustrator Gu Chaoxi.
Gu Chaoxi, a Buddhist girl who is keen on studying the structure of the human body. She draws skeletons with anatomical precision, sees through the case with the sobriety of an outsider, and occasionally makes a comment that can leave two elite criminal investigators speechless.
As daily unsolved cases occur one after another, a "Bone Whisperer" hidden behind thirteen corpses gradually emerges. He used corpses to speak and bones to paint, spending twelve years weaving a closed loop that made it impossible to commit a crime. And when the truth finally came out, the three of them discovered that the deepest secret was hidden in Gu Chaoxi's skull that never left his hand.
This is a story about obsession and redemption. Some people spend their lives waiting for the truth, some spend their lives burying secrets, and some spend their lives painting the same skeleton.
