X-ray Gyrations of Eta Carinae, or, Is Presence of Evidence Evidence of   Presence?
  We review the properties of the variable X-ray emission from the extremely massive star Eta Carinae concentrating on the last X-ray minimum, and briefly consider the possible role of a binary companion star on the observational properties of the system.
