At the beginning of episode 6, Haldane and Annika are driving on the Elounda to Fourni road. They find Bernard Kingsley / Duncan Neve lying injured on the floor next to his truck. The road has been found – check out the episode 6 page for more information.
I actually found this location completely by chance. I was actually looking for the two locations of the scenes where the Police cars are driving to the funeral in Dafnai (Fourni). This location was on what I believed to be the same road.
