In my spare time, I entertain myself by writing a series of mystery novels. The first novel was The Elvis Bird, and the most recent is Death of a Golden Bird. They are about a southern ornithologist who researches birds (The Ivory-billed Woodpecker and the Golden Eagle) and stumbles over murders. Both novels are available on Amazon in paper and Kindle. These days, I am working on a third novel in the series. You can read more about them at dewoolbright.com .
