There are few things in today's desensitized society that I think will shock audiences. But the Playcrafters Barn Theatre's Second Samuel, by author Pamela Parker, manages to shock in its secret that's almost carried to the grave by Miss Gertrude, a deceased woman who is never seen on stage. That secret creates the play's tension, and ultimately leading to a lesson in tolerance that avoids being too preachy, and that applies to the acceptance of anyone's differences.
