One year ago on 2 November, seven people sat down to dinner at the restaurant "Luxembourg". One of them, Rosemary Barton, never got up. She was thought to have committed suicide due to post-flu depression. Her husband, George Barton, received anonymous letters saying that Rosemary did not kill herself but was murdered. George started to investigate and decided to reconstruct the dinner at the same restaurant, inviting the same people as well as an actress that looked like his late wife. The actress did not arrive and that night George died at the table - poisoned, like his wife, by cyanide in his glass.
