"Magnus Bowles' was of course a fiction, invented by Montague Small." Blaise had told Monty about his affair with Emily. In order to help Blaise prevent his wife from suspecting of him, Monty devised this character. "You need a consistent story... one with a built-in safeguard against investigation.' And that's how Magnus Bowles came into being, invented and kept going as a changing person by Monty." Thus, Magnus Bowles was supposed to be one of Blaise's patients. Blaise, 'devoted entirely to his patients', would answer every call for help from 'Magnus' in order to explain his continued absences from home.
