Yet when the expedition had sent in unmanned landers, that was what it had found. Some sort of native alien, surviving on the barren planet.

Now Sallman would have to find out how he could survive on a planet so cold that sulphur was solid and water was liquid - and how to stop the source of the deadly drug!
