The opening line is always a fun thing, and that was a great example of one that's pure win. One I always remember is technically two lines, but made a great opening : "To say that I met Nicholas Brisbane over my husband’s dead body is not entirely accurate. Edward, it should be noted, was still twitching upon the floor." - (from Deanna Raybourn's Silent in the Grave, an interesting little Victorian era set mystery).
I have to admit, Stephen King can be very hit or miss with me. He has lots of great ideas, but sometimes his writing works and others it's just annoying.
