I'm trying to find the name of a film - a suspense thriller possibly black and white from the Sixties or early Seventies.
The plot is along the lines of a female driver picking up a male hitch-hiker. Throughout the film we see newspaper headlines of a series of murders which look as if they may have been committed by the hiker.
There is a scene that I particularly remember shot in the old Tollgate CarPark at the bottom of the M32 in Bristol - the car going up the series of spiral carpark ramps.
SPOILER: The twist in the film is that it's the woman rather than the man who is the killer.
