A family has been found murdered in the heart of 1920s Shanghai. But what could have compelled them to open the door to their killer? Inspector Danilov has always taken a unique approach to detective work. So, when he's asked to investigate the violent death of a fellow police officer, killed in action, he doesn't think twice about turning his attention to a different case altogether: the brutal murder of the Lee family, found massacred in their own home. How could the deaths of an ordinary family account for a shooting halfway across the city? And what clues lie with the letter found clasped in the dead girl's hand? Inspector Danilov's instincts tell him he's close. But when the investigation reveals deep corruption at Shanghai's core, Danilov faces a choice: probe further, and expose the evil underbelly of the city? Or shy from duty...and keep the few people he loves safe?
