Fiction by Mary Jane Clark.
I've read several of Mary Jane Clark's books and they are fun and fast-paced mystery/thrillers. Her novels are similar to the "Queen of Suspense" Mary Higgins Clark, and she is quite fortunate to be placed alphabetically right next door to that author.
This particular novel centered around an entertainment critic who gets mixed up in a murder/disappearance at a theater. It was a good read.
I also read recently by this author: Footprints in the Sand, Dying for Mercy
