And apparently I've been librarianing with my eyes closed, because I was completely unaware that the great man had published a book in 2007 called Elmore Leonard's 10 Rules of Writing. (I ask you: How do these things get by me?! Of course, I only discovered his greatness in 2009, when I listened to his amazing Western/mystery The Hot Kid. Better late than never, eh?)
During the interview, they alluded to a couple of Leonard's rules, including, "Never use the words 'suddenly' or 'all hell broke loose.' This rule doesn't require an explanation."
There are various sites out there on the interwebs that list his rules, and this one is the one I like best.
So, yeah, I've placed a hold on that 96-page book of his, because I adore that man's writing style.
