This is okay and Samantha Eggar very good but is just not sinister enough. My print was not a very good one which didn't help but I didn't feel particularly engaged early on and although for me it brightened up when John McEnry comes in, his character is too enigmatic to seriously help one's involvement in trying to work out just what the story is. The final denouement and cumbersome and involved flashback details as outlined by Oliver Reed did not annoy me as it has some (I've watched many a giallo where the 'explanation' is more ludicrous than the earlier tale) indeed it struck me as more interesting. There just wasn't enough actually happening in the bulk of the film for one to get one's teeth into. I suppose in some giallo these gaps would be filled with rising bosoms and falling dresses but here alas were left with the best of efforts by Ms Eggar, not particularly well dressed at all.
