The mysterious Sir James is an MI5 operative and very charming with it. He's used to manipulating people in a kind way to get what he wants - but he's not a bad person by any stretch of the imagination. He injects some fun and potential romance into the Chase family household and also offers Kasia the possibility of returning home to Poland. He's a bit of a whirlwind from the moment he arrives, and is immense fun to play.
