Query: Couldn't put it down!

It was strange being in the head of a black widow, who also happens to be a successful interior decorator in one chapter and then in the head of a government agent in the next. But it worked. I kept turning the pages to figure out when their paths would cross or how it all fit together. I kept hearing the lyrics to the song "The Bitch is Back" whenever Nora returned to another lovers' home.
