From
Wind/Pinball: Two Novels, by Haruki Murakami:
In the bottom of the first inning, Hilton slammed Sotokoba's first pitch into left field for a clean double. The satisfying crack when the bat met the ball resounded throughout Jingu Stadium. Scattered applause rose around me. In that instant, for no reason and based on no grounds whatsoever, it suddenly struck me: I think I can write a novel."
The foreward (above) to "Wind" reveals how Murakami decided to become an author. The result is two short works that share a narrator and characters and setting.
