5, 1980), Christopher Lehmann-Haupt wrote: Much of the book was written during the author's last burst of productivity in 1979. As Capote began to eschew partying and carousing in favor of maintaining a regimented writing schedule at his Turtle Bay residence, his newly disciplined elan gave brief hope to those who felt his addictions were beyond help. Ten of the 14 pieces had been commissioned for Andy Warhol's Interview and initially published in the then-regular "Conversations with Capote" feature. At that point, Warhol was one of Capote's few remaining champions, and Capote's need for support likely necessitated the completion of the work at a rapid clip. Warhol submitted reluctantly to Capote's demand for full creative and editorial control, though editor Brigid Berlin proved adept at winning the author over when changes were absolutely necessary. After the collection's publication, Capote all but terminated his relationship with Interview, and his health and self-restraint continued to deteriorate. In a 1992 piece in the London Sunday Times, which had earlier serialized Music for Chameleons, reporters Peter and Leni Gillman investigated the source of "Handcarved Coffins", the piece Capote subtitled "a nonfiction account of an American crime". They found no reported series of American murders in the same town which included all of the details Capote described—the sending of miniature coffins, a rattlesnake murder, a decapitation, etc. Instead, they found that a few of the details closely mirrored a case on which Al Dewey, the investigator Capote portrayed in In Cold Blood, had worked. They concluded that Capote had invented the rest of the story, including his meetings with the suspected killer, Quinn. Capote previously furnished a full account of the Dewey case during a May 20, 1975 appearance on The Tonight Show with Johnny Carson. While noting that he had no desire to write another true crime opus, he recalled that one particular case had caught his interest. Thereafter, Capote went on to describe the rattlesnake murders, the burning farm house murders, and other details. He also stated that he couldn't divulge all the details of the crime (including the locations involved) because the police didn't have enough evidence to arrest their suspect, and that there were others on a "list" that the killer was still stalking. He stated that the police had the suspect under constant surveillance and were awaiting further action. This account seems to follow the portion of the finished story
