Nameless Poison - 2013 - 7/10
AKA - Na mo Naki Doku / 名もなき毒

Eleven part J-dorama, following two commonplace mysteries.
In the first half, the Chairman asks his son-in-law to assist the grieving daughters of his recently killed chauffeur.
They want to write a simple memorial about their father, with the hope whoever accidentally killed him confesses.
Only - as the son-in-law delves into the chauffeur’s history, a dark history emerges.
The second half is about a serial poisoner who is injecting cyanide into drink cartons in convenience stores.
Again, the son-in-law is drawn in, while his wife pleads, “Quit getting involved!”
So say we all.
No police - no detectives - just an ordinary man trying to help others, not always succeeding.
Even though he works full time, and has family obligations, he spends much of his free hours in a fabulously empty cafe.
