Something Intangible by Bruce Graham now at Gulfshore Playhouse, falls in the currently popular mode of using thinly disguised historical figures to engage the audience. “The Aviator’s Wife” does this for Anne Morrow Lindbergh. “The Paris Wife” is “about” the Hemingways. As in the case of those books, “Something Intangible” raises questions in one’s mind. How true to life is this story? Does the writer know something we do not? Does it matter?
