Circa 1963 - 1967. It was a story about a man discovering an invisible creature in his apartment. He eventually captured this creature and kept it tied up on his bed. It lived for a while but after a few days died. Well written story that I believe appeared in a "best of SF" collection. The name of the author and title of the story escapes me. IT IS DRIVING ME CRAZY. Can anyone help?
