Either Audrey has failed to grasp your explanation of the brush strokes completely (this was my first guess), or you have changed your "expert opinion" since Audrey first grasped it. Which is it, Jon?
She claims that the cartouche starts at the "bottom" at the brush strokes go "upwards."
You, however, explain that it goes from "top to bottom" - or, if in a horizontal position, the lateral inscription was written from "left to right" which means that Audrey's understanding runs counter to your own.
Is is any wonder that Creighton's defence team is considered a "shambles" by court attendees?
