“There’s a derelict space station near the edge of the galaxy. It was empty until Fishface Pesco from the Gillyx system opened “The Tavern at the End of the Universe” to serve as a stopover for the assorted nomads wandering in space. Some of them are strangely familiar to us Earthlings!
They include antiquated spaceship captains, lost hitchhikers, princesses with wacky haircuts, time-traveling physicians, absent-minded bounty hunters—humans, androids, furry creatures, amphibious types or any combination. They come here to rest, relax or maybe close a shady transaction in a private meeting room.
One night, a rowdy crowd gathers to hear the cantina band. The music stops suddenly when a body, spattered with what looks like blood, floats past the viewscreen. Fishface has been killed! He must have been ejected into space from the closest airlock, and no one had access except the people in this room. One of YOU is a murderer!”
