Binhai City: a modern metropolis that looks glamorous on the surface, but seethes with hidden currents. A murder meticulously disguised as a heart attack sets off a series of killings. The killer has an expert grasp of medicine and criminal investigation, and each crime is a cold, mocking taunt aimed at the police. The only signature left behind is an ancient coin that vanishes from the victim’s chest. Criminal investigation expert Lu Chen is drawn into the case, and the investigation touches a hidden wound of his own: his younger sister’s mysterious death seems to echo strangely in the case before him. The real mysteries are these: How does the killer create a perfect alibi? Where does the vanished coin lead? And are the fragments of memory buried deep in Lu Chen’s mind the key to solving the case, or a deadly trap the killer has laid especially for him?
