To me this wasn't a giallo in the customary mode of being a lurid murder mystery on the border of horror. It's more like something in the realm of "Sleuth" or "Deathtrap," in that it's a single-house-bound, talky series of narrative twists in what we think is happening turns out to be something else, then even that illusion is stripped away. Is it a murder mystery? Does a murder even occur? You'll have to watch to find out. It's also similar to those above-named movies in that it is adapted from a stage play (cited at the end), and feels it. The acting is good, though I found the French lead actress (familiar from Eric Rohmer movies) a bit annoying--perhaps more because of her whiny English voice dubbing than anything else. Still, it's a somewhat static, gimmicky narrative concept, so I can't say I was as enthused about it in the end as some other posters here. Though well-directed, it's the sort of chamber piece that could just as easily have been done for TV.
