I'd like to ask you if you've got a video cassette of "And then there were none" by Agatha Christie, in English?
You can search HelMet libraries video casette collection by choosing keyword search http://www.helmet.fi/search/X for keyword you can put Agatha Christie and change all types of material to video casette. By clicking the title of the video you get the location infomation and the original title. Most of the video collection are spoken in original language, only the subtitles are in finish.
Unfortunally HelMet libraries collection don't have "And there were none" by Agatha Cristie. But there are several other films made from her books. You should find "And there were none" videocasette in any video rental company.
