After finishing the first draft and returning it to Lippincott, the manuscript, at that point titled "Go Set a Watchman", fell into the hands of Therese von Hohoff Torrey — known professionally as Tay Hohoff — a small, wiry veteran editor in her late 50s. Hohoff was impressed. “[T]he spark of the true writer flashed in every line,” she would later recount in a corporate history of Lippincott. But as Hohoff saw it, the manuscript was by no means fit for publication. It was, as she described it, “more a series of anecdotes than a fully conceived novel.” During the next couple of years, she led Lee from one draft to the next until the book finally achieved its finished form and was retitled To Kill a Mockingbird.
What was the name of  the editor who helped Lee finish her book? (If the question is unanswerable, say "unanswerable")
