Thirteen Years of Dust is the best Light On/Mist Theatre suspense thriller iQiyi has released since The Bad Kids and The Long Night in 2020. This tightly written mystery cum police procedural is gripping from the start. An eerily staged crime scene reminds Lu Xingzhi of a serial killer that had terrorised Nandu thirteen years ago, when he was just a rookie detective. Starting with his mentor Wei Zhengrong, he gets the old investigative team that had profiled and hunted the killer back together again. They have unfinished business to get down to. Thus begins a thrilling chase for the long hidden killer who seems to be taunting them, "Catch me if you can!"

The way the narrative unfolds in parallel between the present and the past is mesmerising and immediately made me invested in the main characters, including potential antagonists. In the present, the characters are older yet wear unmistakeable vestiges of the past that make them seem still touchingly familiar. We see what they were like juxtaposed against what they have become. This invokes a haunting sense of nostalgia over what was lost and what could have been. This captures the essence of what made CBS's Cold Case one of my favorite police procedural series. Wei Zhengrong seems the most markedly affected. In sharp contrast to the rather rough, dismissive, and bitingly cynical cop in his prime, he becomes a muted, wiser and oddly broken shadow of his former self. Lu Xingzhi on the other hand has delivered on his early promise and come into his own but his family life is disrupted.

Chen Jianbin and Chen Xiao anchor the stellar cast in this production. Both are charismatic and convincing actors with such incredible chemistry that it evolves to reflect the passage of time. They each subtly take on some of the other's traits thirteen years later, indicating how deeply they influenced one another. It is not easy to play characters that have aged and changed over thirteen years, yet remain essentially that character. Beyond both leads, every main character in each of the many cases delivers riveting portrayals of both their younger and older selves. This brought the victims to life through the eyes of people who knew them, loved them, feared them, envied them and may very well have killed them! The side story that moved me most was that of the gangster and the dancer.

The plot is very well designed and is a lot more whodunit than howdunit. It is set in a time when use of forensic technology was nascent and primitive. So the cases had to be approached the good old fashioned way of narrowing down suspects to who had motive, means and opportunity. The evidence and clues are all presented in an even handed manner; there is no attempt to hide anything from the viewer. From early on, the audience has enough clues to credibly build a case around at least two suspects at any given time. While the solution is not a huge surprise as the killer is well concealed but far from invisible, it still comes with a decent twist. It is a surprisingly dark story with a chilling ending for a c-drama. The production maintains an unsettling tension of a disturbing and menacing presence throughout. If I have to criticise, the staged crime scenes are a bit pretentious and the explanation of the painting and its significance is on the weak side although it just passes muster.

Overall, this is a well written and nicely executed crime thriller that will satisfy exacting crime buffs. A highly recommended watch that I rate 8.5/10.0.
