Here is an interesting observation: According to the omniscient Wikipedia, Robert Ludlum wrote 27 books in the 30 years of his writing career while he was alive, from 1971 to 2001, and in the 22 years since then has produced 30 books. Simple arithmetic shows us that Robert Ludlum has been much more productive dead than alive. Think how many books he might have written if someone had killed him in 1971!
