Supported by such belief and an understanding wife who took "basically all household duties", Qin completed his 220,000-character first draft on May 1.
He started Voice of the Dead with a case that transformed him earlier in his career.
It was July 1999. Qin was a summer intern with the forensic department of Tongling Public Security Bureau in Anhui province. One day, when he opened the body bag for the autopsy, he was shocked to see a familiar face - his schoolmate in primary school.
With the help of senior colleagues, Qin identified the killer through his forensic knowledge.
"Forensic doctors often work under tremendous mental pressure," says Qin. "The deceased might be your friends or colleagues, but no matter how heartbroken you are, you still have to do your duty at the autopsy table."
Apart from writing, Qin is also enthusiastic about making basic forensic knowledge better known on his Weibo page. His professional expertise and humorous expressions have attracted more than 28,000 followers.
In May and August, the world was shocked twice when two Chinese, Lin Jun and Liu Guanghua, were murdered and dismembered in separate cases in Canada.
By August, Qin had responded with an article online, shedding light on the two cases from the forensic perspective.
Voice of the Dead is Qin's first novel, but it definitely will not be his last. His second novel, already in final editing, will come off the press in February 2013. He plans to expand the Voice of the Dead into a trilogy before the end of 2013.
