Query: Stone is too enamoured with his vast vocabulary...

Just because you know how to "use it in a sentence" doesn't always mean that you should... especially if the use of all the grand words one knows interfers with the telling of the story. Stone is too enamoured with his vast vocabulary and thus, alas, the story just does not flow as it might if he wrote as if he were telling us a story rather than composing one. It is too "literary" and trying to impress with his "writing ability" rather than "storytelling ability".
