Things to keep in mind:
The secret of the wych-elm.
The first—“Who put Luebella down the wych-elm?”—was followed by many other slight variations, such as “Hagley Wood Bella” found on a wall in Birmingham. As time passed the messages took on what was to be their settled form for years to come: “Who put Bella in the wych-elm?” they asked. It was thought that the original messages, carefully written in chalk in three-inch-deep capital letters, were probably written by the same hand, working at night.
