"The Cosmic Snare" by Milton Lesser is a science fiction novel written in the mid-20th century. The story is set against the backdrop of sub-space travel, exploring the vast emptiness that serves as a channel for instantaneous travel between distant star systems. Ultimately, the book delves into themes of survival and the interplay of danger within the unknown dimensions of space. The plot centers on Liddell and his wife, Linda, who are stationed at a sub-space transfer station. When a notorious escaped prisoner, Jason Short, materializes unexpectedly at their station, chaos ensues. Liddell confronts the killer, who takes Linda hostage and demands to be sent to a distant planet. In a daring move, Liddell deliberately alters their transfer coordinates to trap Short in sub-space along with Linda, thereby allowing him to rescue her. What follows is a tense confrontation in the featureless gray of sub-space, where Liddell must battle Short in a realm that defies the laws of physics. The story culminates in Liddell bringing them back to normal space while contemplating the intriguing possibilities for the future of sub-space travel. (This is an automatically generated summary.)
