Book 593: The Innocent Mrs. Duff/The Blank Wall

The Innocent Mrs. Duff/The Blank Wall, by Elisabeth Panxay Holding, Quality Paperback, 2002.

Both of these stories are suspenseful and very well-written.  The first story is not so much about Mrs. Duff as it is Mr. Duff; she doesn't even get to react very much.  The second story is about a middle-aged mother of teens, but she is more of a reactor than actor.
