This is a long shot

I am trying to find these movies. I can’t  remember the name or really much of the plot.  I watched this movie some years ago but what I do know is that It was a least a mystery trilogy. There was what I think a group of detective/people, the lead person was a man with whiteish hair I think and there was one girl in the group.  The visuals through out the movie were on the gloomy side, and the movie poster has them standing in the middle of some trees but in like the same bluish gloomy lighting as the movie.  I will take any and all ideas of what you think it could be.  The movie poster keeps popping up in my head and I would just like to be able to put a name to the image.  If it helps I watched it on Netflix.
