The Killer Wore Gloves (1974)

Neat little Spanish giallo from director Juan Bosch starring Gillian Hills (demons of the mind) as Peggy Foster. The film begins with a man getting his throat slashed by an unseen assailant with a razor blade. His girlfriend (Peggy) later learns of his disappearance and is drawn to an old abandoned airport where she is shot at but manages to get away unscathed. Things take a turn for the more mysterious when the lodger she took in turns up dead then another man arrives making claims that the dead man is an imposter and he is the one meant to take the room. Soon people around Peggy begin to be killed off as she starts her own investigation into the mystery. This is a good quality print in English.
