This is a long shot. Many years ago (late 70's early 80's) I recall watching a televised version of a murder mystery stage play. As I remember it, it is somewhat like Deathtrap. The plot centers around a successful author of children's books. This was years ago, so the story line is hazy. But I distinctly remember one character being killed on stage, hauled off and buried in the woods, only to return in the second act. He was neither dead nor buried deeply enough. Does any of this ring a bell with anyone? Title? Author? Anything.
