I know this wasn't written by King, but try it anyway. It is a book called 'Victorian Horror Stories", by Mike Stocks. It's absolutelly brilliant, and there is a story there, 'One Silver Bullet', about werewolves. Trust me, some of the stuff in that book is really freaky; great story-lines and great description. One of my favourites is called 'The Original Revenge'; it's sure to satisfy any sadistic cravings! lol.
