And Then There Were None

Ten people are invited for a weekend on an island by a Mr U. N. Own, but he isn't on the island. At dinner a record is played, by that all the people are accused of murder, suddenly the first of them is dead, then the next... It seems to be that one of them is the murderer Mr. U. N. Own, but the person in suspect is always the person who is murdered next. At last only two people seem to be left.
