Jack Williamson: Salvage in Space: To Thad Allen, meteor miner, comes the dangerous bonanza of a derelict rocket-flier manned by death invisible.

This is an SF tale of excitement, danger, derring-do and strangely enough, love. A lonely and very poor asteroid miner, slowly collecting bits of metallic ore in the asteroid belt on his v-e-r-y slowly accumulating 'planet' of debris, sees and captures a derelict space ship with a horrible monster aboard .. as well as a dead but lovely girl. How does it all end? Well you will need to listen to find out. One of Jack Williamson's early tales that earned him his reputation as a master story teller.
