The Edge of the Knife: A Post-1930, Science Fiction, Short Story Classic By H. Beam Piper! AAA+++

A tense little story about a history professor who finds he can see into the future. Careful details make the story come alive, and make up for some one-dimensional secondary characters. The story evokes the post-McCarthy-era university system, and the preservation of tenure rights is a big issue. So is the tension between hiding what you know is true but can't admit, and bringing truths out into the open before society is ready to hear them. It's a fun read.
