Normally, gunfights are to be expected in a detective drama. This show isn't like that, they use data and science instead of using guns to find criminals. It finds you from the dandruff in your hair, the tissues under the nails, the sound of the clock on your wrist, the medicines you use, the glass fish bowl in your home, fingerprint and swap analysis, blood type, who called you last. An international masterpiece prepared by an expert in his field. The goal here is not to find the criminal, murderer or the person who will go to jail, if you came for this this series will give you nothing. Fantastic..
