I am trying to find a short science fiction story I read 25 or more years ago (without telling my age :) ). I'm fairly sure it was not part of an anthology.
In it, an astronaut is sent to investigate a strange ship in space. I can't remember if the ship sent a distress signal, or if it was simply found apparently derelict. He boards it, and is greeted by a man with a shaved head living in a utopian world, where the entire ecosystem of the ship is a sustainable garden.
He wishes to escape and attempts to several times before slowly finding he loves the peace and tranquility of life in the garden and stays. The story ends with him becoming the next shaved head man ready to trap another astronaut who has been sent/discovered the ship.
The cover (from memory) has a shaved headed man in a space suit helmet laying in wait. I wish I could give you more, but that is all I remember, except that I really enjoyed the story and have been trying to find it for several years. It isn't very long, perhaps a couple of hundred pages.
