I watched the men leave their helicopter. Suits. Ties. Polished shoes. Straight walk. Emotionless I waited until they entered the small house at the end of the field. Slowly I crept towards the helicopter. The setting sun hid me from unwanted observing eyes and the high grown grass as well as my abilities to move anywhere without leaving marks did the rest to make me invisible. Nobody would ever be able to prove that I had ever been here. I reached the helicopter and crawled below it. With quick fingers I attached the little silver cylinder below the tank. One last glance back to the cottage and I crawled back to the big tree that I had picked out for my hiding-place hours before. I placed a blue hairclip in the branches of the tree and quietly backed up until I was sure I would not be seen by the men even they looked out the window. I was done here. 
Two hours later newspapers and radio broadcasts would report about three businessmen who had died when their helicopter had exploded due to unknown reasons.
