I was excited by this drama because the backstory sounds like a Chinese version of a favorite mystery series "Mistress of the Art of Death" which is also about a medieval female crime solving coroner who teams up with a sexy man to solve cases. Like Miss Truth, the novel is about a strong and smart woman, ahead of her time in both forensic knowledge and life attitude. I was both disappointed and relieved that this drama does not dive into the forensic aspects of the cases with the chillingly thrilling gruesome detail of my beloved novels. Indeed all of the gory props are almost cartoonishly fake and any macarbe detail is rather cursorily handled. While set in Tang dynasty, the story-line barely acknowledges the main historical characters and events of the day. Nonetheless it is a short and very enjoyable watch that really stands out in its repudiation of common tropes. 

The drama is about a talented and adventurous young lady coroner's journey of self discovery. As she helps solve cases, unearths Marquis Sui's legendary pearl and unveils a grand conspiracy; she also finds herself and discovers the truth of her heart's desires. The drama starts with a bang by establishing Ran Yan's credentials as a brilliant forensic analyst as she is extorted to solve a murder by the criminal underworld in exchange for her shifu's gambling debts. This tosses her right into the crosshairs of both Xiao Song, a nobleman and the emperor's trusted investigator and fixer and Su Fu, a mysterious assassin who saves her life. They are both tasked by different masters to recover Marquis Sui's pearl, which is part of a larger conspiracy that is the drama's overarching plot. The drama maintains an exciting pace, with danger and intrigue lurking around every corner and builds to a strong finish on a high note with a surprise reveal. I was only able to identify the ultimate mastermind by elimination; there were not enough clues or hints along the way to figure out their identity or motives.

As a big fan of strong, smart female characters, I was baffled by how difficult I found it initially to like newbie Zhou Jieqiong's Ran Yan. She is almost immediately and recklessly infatuated with the thrillingly inscrutable Su Fu and is unquestioning of his motives. Yet this sharp tongued vixen is distrustful of and lashes out inexplicably and ungratefully at Xiao Song, who appreciates her talents immediately and employs her as his coroner. This gives her the means to escape an unwanted marriage arranged by her indifferent father and cliche evil stepmother and half-sister. She snidely calls him a merman in a tone that implies fish face or worse, dead fish and bristles when he affectionately refers to her as his foxy lady. Nonetheless they companionably squable their way through a number of well constructed cases and become a likable and effective crime solving team. While Ran Yan is the titular character, veteran actor Toby Lee's Xiao Song is the sleuth that puts all of the clues together and truly anchors all of the cases and the drama. His character was well written and masterfully portrayed - between his teasing banter, merciless goading, stern rebukes and unyielding support he managed the prickly Ran Yan perfectly. While he arguably cut her too much slack, he knows exactly how to get under her skin. He is no doormat either and knows when enough is enough. The surrounding characters are cleverly and realistically written in a way that reacts to the other characters' flaws; for example I could totally relate to the shrewd and loyal Bai Yin's dislike and ranchor toward Ran Yan for treating his master Xiao Song so poorly.

For once, I actually enjoyed the dreaded love triangle in this drama, something I normally have zero patience for. Initially I didn't like Ran Yan so I didn't really care if she made a bad decision. Ultimately she is a resilient, strong willed character who knows her own mind, is not just defined by love and can roll with the punches so there is no tragically wrong choice for her. It is completely in character for her to break all the rules, throw caution to the wind and indulge in a dangerous, exciting and most unsuitable man - something hopefully every woman gets to do at least once in a lifetime! So does she stay with the one who loves her or go back to the one she loves? All I will say is that the triangle was fittingly, somewhat poignantly and DECISIVELY resolved. She totally manned up and picked the one with the nicest chest (a purely subjective but well researched opinion)!

While I never got to like Ran Yan (she is deliberately written to be really not that nice) and didn't emphatize with her, I reluctantly admired and respected her. This drama really showed me, someone who pounds on the table for strong female leads, that I may have been more socialized to like and accept the conventional c-drama female lead than I would like to admit.

I think all things considered (production value was not that high) this drama should be a 7.5-8.0 but I gave it a 8.0 for being so different in the best of ways in terms of avoiding most (not all) cliches, very smartly written and unconventional characters, hot male leads, exciting pace and cases and ending at the climax.
