These detective stories are adapted from the novels about Poirot by Agatha Christie.

I am a big fan of the fashion from this era and the production of sets and wardrobe and lighting are terrific.
There are two handsome male leads and if this wasn't under the strict Chinese censorship I could imagine a very lovely BL story.

They flirt and Qiao Chu Sheng plays the role of protector /provider to the more ingenious Lu Yao. The dinner with violin and gift giving is very sweet.
Together the brawn and brains make up the investigative team to solve a series of murders. Lu Yao deduces the solutions from his science and medical knowledge and Qiao Chu Sheng provides the martial arts and police back up. Both actors do a terrific job inhabiting their roles and we learn about their backgrounds and what has shaped the characters they become.

There are interesting side characters - Salim and Lu Zi Fu in particular.

I like the comedy and bickering between all of the main characters. Leon Zhang proved he can do manga style comedy in Mr. Pride vs. Miss Prejudice. The rest of the ensemble contribute well to the complex mysteries.

The acerbic reporter, Bai You Ning, who makes up the trio, is less successful in adding to the story. More of an annoyance. She has zero romantic chemistry with Lu Yao and the writers have badly scripted the ending.
We are left with a cliff hanger but I hope they read the commentary regarding Bai You Ning and maybe lose her out to sea.
Also at odds with the drama is the poorly executed parts where English is spoken. Out of sync and not matching the voice of the actors it is a jarring annoyance.
