It was after several years that I heard the story about the disappearance of my half sister. I was four then and my half sister who was then 23 went away with two aliens to the planet Garhia. Yeah. That one in the Sombrero Galaxy.    And guess what? She was going in my place as Bob Downhill! It is said she entered the Garhian queen's service somehow. Only God knows how! I swear my uncle Tom must have had a hand in it,the way he avoids the subject. Well, this is her story as recounted by herself.
