Terrific! Frederic Brown was one hell of a good writer. Prior to this I had only known of him as a writer of Sci Fi short stories and in that capacity I loved his stories even though they were in a genre that I tend to avoid. When I found out about a volume of short crime fiction I bought it asap. It was not disappointing. His work in both genres originally appeared in the pulp magazines of the day, in this case Alfred Hitchcock's Mystery Magazine, Black Mask, etc.
Brown shows himself a master of the short story. He is concise, to the point and creative in every instance. I found myself admiring the short story genre to the extent that I want more of it. Jorge Luis Borges, also a master of short story, although very different stylistically, liked the form because he felt when you read a novel by the time you get to the end you've forgotten the beginning. That's a valid point. A short story can be read in one sitting. While reading this I found myself thinking at times that although I loved it, how well would they work for someone younger who grew up not knowing the world of no tv and no cellphones and no pulp magazines?
