Eyeball

Paulette Stone joins a party of tourists in Barcelona. She is joined shortly after by Mark Burton, her married boss with whom she has been having an affair. Somebody begins killing members of the tour party – in each case gouging out their left eyeball. The only clue is that the killer is wearing one of the red raincoats given out to members of the tour party. As the Spanish police investigate, suspecting various members of the tour group, Mark realises that his wife Alma has come to Barcelona and might be the killer.
