In Cold Blood was first published as a four-part serial in The New Yorker, beginning with the September 25, 1965, issue. The piece was an immediate sensation, particularly in Kansas, where the usual number of New Yorker copies sold out immediately. In Cold Blood was first published in book form by Random House on January 17, 1966.[33][34]
The cover, which was designed by S. Neil Fujita, shows a hatpin with what appeared originally as a red drop of blood at its top end. After Capote first saw the design, he requested that the drop be made a deeper shade of red to represent the passage of time since the incident. A black border was added to the ominous image.[35]
