Untraceable Evidence is another police-crime TVB series, but I think it has a nice new twist showing the forensics side of crime investigation. Tsung Ka Yuen is an excellent police officer whose team always seems to get assigned to the most interesting cases in all of HK (of course!). He works well with his police colleagues and is looked upon by everyone as the big brother. Ka Yuen is also very close to his dad, brother and stepmom. Our impression of Ka Yuen deepens a little later when we learn that his wife died from cancer and that he hasnt dated anyone since. Later in the story, we will see Ka Yuen start to like Pauline but before anything happens with her, he dates Siu Tong Choy, one of his colleagues.
