Of course, we already knew that mysteries rock. But now there's research to support this: a recent NEA study showed that 54 percent of readers like mysteries best, with thrillers (mystery's fraternal twin who likes to wear running shoes) at 32.6 percent.
That's a combined 86.6 percent! It's probably statistically incorrect to just add those two numbers, but I'm doing it anyway. The reading public has spoken: mysteries and thrillers rock.
