Pascal Sagittaire is secretary and scribe to Comte Mathieu de la Marche, residing in the comte's household in Paris. He is a highly organised and intelligent man, small of stature and mouselike in his appearance and movement. Pascal often sports a set of reading eyeglasses to assist his eyesight, a recent invention from Italy. He is a sober individual with a matter-of-fact delivery, and is very serious about his role as secretary to the French spymaster.
His honorary surname of 'Sagittaire' is a mockery of his youthful failure to use a bow when called up for military service under Comte Mathieu's father. Pascal wears the name as a source of pride, considering his intellectual abilities a more than adequate replacement for physical strength.
