Author Dean Koontz has written more than 100 books - including thirteen number one bestsellers.

"You're incredibly prolific," says CBS' Anthony Mason. "Where does that come from?"

"The imagination's a muscle partly. And the more you use it the easier it becomes," says Koontz.

His success - he ranks number six among the world's best-paid writers - has built him a stunning California home he calls "Amazing Grace," with carved book cases in his library.
