They called us series " The Paris murders" on PBS masterpiece and also miss label series 4 episode one as season one episode one. If you choose to watch as a paid subscriber of TBS masterpiece you will be shown the first episode of the fourth season with no background of Seasons 12 and three to help you understand the main character. I find this to be extremely annoying and will probably not watch past this first episode. There are better options out there amongst the many excellent French crime shows. On the slightly lighter side you also have Candice Renoir which is available on the acorn channel.
