The Fly

Industrialist FranÃ§ois Delambre is called late at night by his sister-in-law, Helene Delambre, who tells him that she has just killed her husband, AndrÃ©. Reluctant at first, she eventually explains to the police that AndrÃ© invented a matter transportation apparatus and, while experimenting on himself, a fly entered the chamber during the matter transference.
