NEW YORK — When last we talked to Marie Rudisill, Truman Capote's aunt, she was bound and determined to publish the 8,500-word novella that she had found in a paper bag just days after he died in August, 1984. "Cousin Bud," as the work was titled then, had been stashed away in the attic of Rudisill's 200-year-old house in Beaufort, S.C. Capote, then 22, had given the story to his aunt shortly after he wrote it in the summer of 1946, but until Rudisill went upstairs to search out some Capote family facts for the mortuary in Los Angeles, she had forgotten all about it. Now, more than two years later, and retitled "I Remember My Grandpa," the work is out in the December issue of Redbook--but not without some doing on Rudisill's part. Capote's 76-year-old aunt reports a major runaround on the part of four lawyers and most of the U.S. Copyright Office. Informed initially that "it would be impossible to get a copyright for a dead person," Rudisill persisted. "I said I know it is not impossible because I am determined to do it," she declared. Her next appeal was rejected, however, because she failed to include all the documents in one envelope. Finally, she remembered, "I said to myself, 'Dammit, I am going to get to the root of this. This is mine. Truman gave it to me. It's a beautiful, lovely story, and it was written completely from the heart.' " So she fired off a letter to the copyright office. "I said we were sitting at the kitchen table, and Truman came in with some papers in his hand. He handed them to me, and said, 'Here, I want you to have this, it's a story I've written for you especially about Bud.' I said, 'Truman, what do you want me to do with it?' And he said, 'Anything in the wild world.' And as he walked out of the room, he said, 'Who knows, someday I might be famous.' " The Capote story carries a copyright in Rudisill's name, a fact U.S. senior copyright information specialist Richard Anderson said was in no way unusual. "We get copyright claims for works that have been authored by people who have been dead, sometimes, hundreds of years," Anderson said from his office in Washington. Rudisill, for her part, got $20,000 from Redbook to publish the story, and is overjoyed to see it printed in a magazine that will "take this pure sweet story into the American home." Said Rudisill: "I'm 76 years old and I'm as bull-headed as they come, but he gave it to me to do with it as I wanted to do, and that's what I wanted to do. I want the world to see it."
