Who is Philip Ketchum? The very first paperback issued in what would become the Dell Map Back series was titled The Body in the Library. It had no map on the back, and it was written by Philip Ketchum. Who? It seems that Philip Ketchum was a writer of Western novels, and that this is his only mystery novel. The only information that I found about him is at Goodreads.
