Talky but well acted English murder mystery that takes place in a large old country estate house. There is some suspense here but it's slow moving. Natasha Parry, who portrays the sweet & innocent new bride, is beautiful & also is a good actress, which is a bonus! Notable for its almost all-female cast. While I watched this film, I thought it was made 1940-1945 (even the hair styles convey this period), so I would have to call it somewhat old fashioned even for its time. Enjoyable, nonetheless.
