Rent Spiral (2005 - 2020)
4.2 of 5 from 85 ratings
The French title, 'Engrenages' means something like 'gears', and this better describes the script's concentration on the interconnectedness of crime and how every piece of a puzzle needs to be solved.
I have seen every series of this on TV. It is one of the best police procedurals ever made. Intense, realistic, funny, dramatic, set in the real non-tourist Paris, with an exceptional cast who are very believable together. It is exhausting to watch, because it is so engaging.
