What’s a nice girl like Ann Rule doing in a genre like true crime?

In this piece in one of her hometown newspapers, true-crime queen Ann Rule, a former Seattle police officer, tells how she found her true calling. Her first book contract was for the story of a serial killer then stalking the Pacific Northwest. When a suspect was finally arrested, she was stunned to discover he was someone she had volunteered with at a local crisis hotline–Ted Bundy. Bundy was convicted and eventually executed, and The Stranger Beside Me was Ann Rule’s first published book.

According to the article, Rule has had 28 books on the New York Times bestseller list.  I can attest that her writing is detailed, thorough, and very readable.
