The Book: “West Wind” by Murray Leinster. Originally published by Astounding Science Fiction in March, 1948, the edition read was in 3 in 1: Three Science-Fiction Novels, (by which they mean somewhat longer short stories) edited by Leo Margulies, published by Pyramid Books (F-899) in 1963.
The Setting: Some alternate Earth, most likely.
The Story: A journalist stays behind when a province is evacuated to allow a neighboring country to take it over. He is, not surprisingly, captured and treated as an enemy agent.
The Science: The story ends with one side of the conflict becoming suddenly, horribly ill from radiation. Turns out, the wind blows west, and one country released radioactive uranium dust into the wind, causing the other forces to die. Radioactive dust causes the enemy army to die, literally, overnight. I’m not sure about the timeline and the ability to focus the dust the story claims, but acute radiation exposure sure can cause death.
The Reaction: I spent the whole story feeling like I had read it before, which is possible. The main character is a little, shall we say, hammy? There’s a thing about coffee in the story which seemed pretty cheap to me. But it’s okay. Just like the previous story from this volume, I was feeling the whole WWII vibe pretty strongly here.
The Cover: Cover art by EMSH. This cover is pretty cool. We’ve got three different species all trying to fix a space thing, and they’re all in specialized spacesuits. Different from a lot of other cover art I’ve seen and I like it.
