In Cold Blood by Truman Capote. If you've ever taken a journalism class, you've probably read Truman Capote's seminal nonfiction book about a murder in a quiet town, "In Cold Blood." It's a classic for a reason. Everyone should read it.
On November in the small town of Holcomb, Kansas, four members of the Clutter family were savagely murdered by blasts from a shotgun held a few inches from their faces. There was no apparent motive for the crime, and there were almost no clues.
