Donna N. Murphy demonstrates how Marlowe, sometimes in co-authorship with humorist Nashe, appears to have "become" Shakespeare on a linguistic basis. She documents a sharp, upward learning curve, with the initial penning of works she examines in the following chronological order: 'Caesar's Revenge', 'Henry VI', 'The Taming of a Shrew', 'Henry VI', 'Edward III', 'Titus Andronicus', 'Thomas of Woodstock', 'Romeo and Juliet', and 'Henry IV', and separates certain plays into Marlowe and Nashe components. Those who read Murphy's book with an open mind will find her work surprisingly convincing.
