Inside the September 25, 1965, issue of The New Yorker was the literary event of the decade: the first of four installments of Truman Capote’s pioneering true crime account, In Cold Blood. Its subject, the brutal murders of the Clutter family in Holcomb, Kansas, had taken place nearly six years earlier, but Capote had to wait until the two convicted killers were executed to give his “nonfiction novel” an ending.
