When You Get to the End

Often I leave the living room when that last commercial break before the end of a TV show comes, which has from time to time caused comment from others in my home. I don't care if I see the last ten minutes of a detective movie lots of times, either. And if I could, I'd let someone else write the last twenty pages of my books.
In most cases, writing the ending doesn't interest me as much as the build TO the end. Once I reveal whodunit, I don't care about the chase through the streets, the abandoned warehouse, or the Grand Coulee Dam. I don't really even care if the bad guy/girl lives or dies. For me, it's all about leading the reader to the point where together we figure out who and why. Once that's established, the chase and the arrest or whatever is just the icing on the cake, and icing is often very sugary and laid on too thick.
So when it comes to writing an ending, I sort of have to force myself. I know what readers expect, and of course I want everything to tie up neatly. But the running/ fighting/confessing part is hard for me. I have to remind myself that the story needs closure, otherwise I might simply do the outdated "I've gathered you all here to explain that there is a murderer amongst you" scene and skip the chase through the dark woods at midnight.
