Detective Kiên: The Headless Horror (Thám Tử Kiên: Kỳ Án Không Đầu, Victor Vũ, 2025)

Five years ago, headless corpses started washing up on the shores of the lake. Believing them to have been victims of the Drowning Ghost, the villagers simply accepted it as a part of their life and carried on as best they could. But Miss Moon (Ngọc Diệp) isn’t prepared to that and when her niece, Nga, goes missing with only her slipper left behind at the lake, she will stop at nothing to find her. 

Luckily, she knows a top detective, Kien (Tín Nguyễn), whom she met when he arrested her former husband for corruption, which is how she knows he’s very good at his job. In any case, Detective Kien arrives to bring a semblance of order to this 19th-century rural town ruled over by a governor who very much seems like he too is probably not really on the level. Though he doesn’t seem to put much stock in talk of the Drowning Ghost, Kien quickly finds himself plagued by weird visions of terrifying monsters and is respectful of the local shaman, who proves very helpful, even if continuing to look for more rational answers.

What he uncovers, however, is that the village can be unkind and judgemental. Nga was rendered an outcast because her mother left the family to be with another man not long after she was born. The other children wouldn’t play with her when she was a child and she’s still regarded as something of a pariah, while her father, Lord Vinh, has always resented her as a symbol of his humiliation. Miss Moon was the closest thing she had to a mother, though she had to leave her too when she was married to the corrupt governor only to return years later when Nga was already a grown woman. 

Detective Kien is open to the idea that Nga too may have simply left with a lover, but the truth is a little more complicated. The problem is that under the feudal order, no one is really free and the younger generation is forever oppressed by the older. Marriages are arranged in childhood and rooted in hopes for social advancement. Marrying a man with prospects is one way a woman can gain status and power, and some will go to great lengths to pursue it. Miss Moon, now no longer married, is something of an exception and operating outside of these patriarchal social codes in asserting herself to look for Nga when it seems no one else will. Detective Kien cautions her not to go with him because the villagers may gossip if they see her walking alone with a man, but she doesn’t really care about that and follows him anyway at which point he is forced to accept her rather than waste time arguing. 

The case of a man who complains he had no choice other than to become a thief after being falsely accused of stealing because the social stigma made him unemployable further emphasises the ways those in power misuse it. Even the mysterious headless deaths at the lake may have a connection with an event 30 years previously in which a whole family were beheaded after being falsely accused of treason while standing up to the oppression of feudal lords. The wealthy elites act with a kind of entitlement in which they bully those below them to affirm their own status. So it is with Lady Tuyet who was seen arguing with Nga after refusing to pay for an order at her fabric stall claiming that it was incorrect. The two women are portrayed as a mirrors of each other, but where Lady Tuyet is haughty, jealous and violent, Nga is gentle and honest. When told she can’t have the only thing she wants in life, she fights back but only for the mildest compromise only for Tuyet to react with rage unable to accept that some may prefer Nga over her.

Detective Kien does what he can to right this wrong while trying to find out what’s happened to Nga and, if possible, save her. He gets a tremendous sword fight after tracking down the secondary villain while even Lady Moon has a hilariously unladylike tussle with her own opposite number as she tries to rescue Nga. The chemistry between them as they investigate the mystery together adds a charming and often quite funny touch to what is otherwise a horrifying tale of heartless cruelty and murder in which the “evil” in the village turns out to be something quite different from that first imagined and possibly much more difficult to exorcise.
