I've been waiting for it for months as I developed a thing for Laurent Capelluto (Mathieu) when I watched Black Spot (another French/Belgian drama on Netflix) which I would recommend. In fact, all French crime drama is pretty great to be honest.
I'm liking it but not loving it. My boyfriend says it's the best thing he's seen this year
From what I've read, it hasn't even really covered what's in the book it's based on, so there is plenty of scope for a second series which is what I assume they're angling for.
