The Fly

Wealthy Helene Delambre is discovered late at night in the factory owned by her husband Andre. Helene stands beside a huge metal press, which has crushed the head and arm of her husband. Held for murder, the near-catatonic Helene refuses to tell anyone, not even Andre's brother, Francois, why she did it. Francois cannot help but notice that Helene reacts in mortal terror when a tiny flies zips through the room. When Francois pretends that he's captured the fly, Helene relaxes enough to tell her story. It seems that Andre, a scientist, had been working on a matter transmitter, which he claimed could disintegrate matter, then reintegrate it elsewhere. After a few experiments, Andre tried the transmitter himself. Just as he stepped into the disintegration chamber, a fly also flew into the chamber. Alone with her husband, Helene abruptly removes the covering, revealing that Andre now bears the head of a fly! His atoms have become mixed up with the fly, and now he is unable to reverse the procedure.
