One Year To Live :

Anthony Burgess war 40 when he learned that he had only one year to live. He had a brain tumor that would kill him within a year. He know he had a battle on his hands. He was completely broke at the time, and he didn't have anything to leave behind for his wife, Lynne, soon to be a window.

Burgess had never been a professional novelist in the past, but he always knew the potential was inside him to be a writer. So, for the sole purpose of leaving royalties behind for his wife, he put a piece of paper into a typewriter and began writing. He had no certainty that he would even be published, but he couldn't think of anything else to do.

"It was January of 1960," he said, "and according to the prognosis, I had a winter and spring and summer to live through, and would die with the fail of the leaf."

In that time Burgess wrote energetically, finishing five and a half novels before the year wad through (very nearly the entire lifetime output of E.M. Forster, and almost twice that of J. D. Salinger.)
