Old B & W Horror Film

Hi I have been trying to find out the name of a film i watched in the early 70’s. It was based on a dinner party in a large house in the UK. The Hostess wore a chopstick in her hair The guests disappeared one by one. This has been bugging me for the past 20 years so i;m hoping somebody can help

Could be one of the versions of ‘And Then There were None’ the Agatha Christie mystery, that has a similar storyline. Also calles Ten Little Indians. Or The Cat and the Canary, theres a couple of versions of that, one definitely black and white.

Was it Dinner For One. Each guest disappears each time something happens.
