On the first episode, The family is pleased to learn that the young Duke of Crowborough plans to visit, seeing him as an excellent match for Mary, but the Duke seems less interested in Mary than in prying in the servants' rooms, and his manner cools completely when he learns that Lord Grantham does not intend to fight the entail. It is revealed that the Duke had a relationship with Thomas. Thomas had actually informed him about the possibility that Mary would inherit, hoping to get a job as valet in return. As the Duke cannot offer him the job, Thomas tries to blackmail him, but he reveals that he has managed to retrieve his love letters from Thomas's room and quickly burns them before Thomas can stop him.
NOW about Mr Pamuk:

However, he arrives with a dashing Turkish diplomat, Mr. Kemal Pamuk, who is in London for the Albanian independence negotiations, and Mary is completely smitten with him. Mary is not the only one: Thomas gets a little too close to the Turk. (They NEVER actually kiss) Pamuk offers to spare Thomas punishment for his indiscretion, provided he will do something in return. During and after dinner, Lady Mary has eyes only for Mr. Pamuk, but when he surprises her by forcibly kissing her, she rejects him. Undeterred, he goes to her room that night, led by Thomas, and manages to seduce her. But in the middle of the night he suddenly dies in her bed.
