The most famous true crime novel of all time and one of the first non-fiction novels ever written; In Cold Blood is the bestseller that haunted its author long after he finished writing it.
On November 15, 1959, 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.
