This story reveals the secrets hidden behind a pharmaceutical company. It begins with the death of Doctor Wei, followed by a string of beautiful women dying one after another. The scent of perfume serves as a clue, while business cards are used as a smokescreen. As the investigation proceeds, a letter arrives from someone dead and buried in a cemetery. The killer is presumed dead, but the deaths continue. One case leads into another, each linked to the last, each more complex than the one before, and every case gives rise to yet another. Case after case forms an endless chain. Saimosi painstakingly pieces together the clues, uncovering layer after layer of evidence until the cocoon is finally unraveled. Then, through his meticulous deductions, the killer is revealed to be someone beyond your imagination.
The killer is an obscure, ordinary, unremarkable woman, and the truth is just as unimaginable. She has not only killed many people, but also murdered her husband and child. Even more astonishingly, a DNA test shows that she is carrying the deceased man's child. Yet the child is not the dead man's. The DNA test has not been tampered with, so how could the result point to the deceased? Is it a twin, or...?
Readers will discover the answers to these questions as they keep reading.
The cases are complex, yet in truth they are quite simple. The killer merely shifts everyone's attention elsewhere, leading readers into another maze and creating a false impression. Often, the key to solving a case lies in details that seem insignificant and unrelated. You won't know who the killer is until the very end. This is a startling revelation.
