Final witness : the story of China's first crime scene investigator

Thirteenth century China, and the Song Empire is crumbling due to endemic corruption and the incursion of barbarians from abroad.

Ambitious men do what they must to get ahead, trampling the commoners who come in their path.

Into the decaying ranks of the civil service, a young scholar called Song Ci is admitted.

He soon gets the chance to prove his worth by developing an unmatched skill for interpreting crime scenes.

In a series of complex murder cases that baffled his predecessors, Song is finally able to dispense justice to the relatives of those whose lives have been lost in the chaos. As the world he knows wanes, Song will be pitted against increasing dangers that will tax him to the edge of his abilities.

But will his efforts be enough to save the empire?
