Which Turkish diplomat dies in Lady Mary's bed in Downton Abbey?

Kemal Pamuk is the Turkish diplomat who dies in Lady Mary's bed in Downton Abbey. He is an Ottoman attaché visiting Downton while accompanying Evelyn Napier during diplomatic discussions connected with Albania.

Pamuk's charm and striking appearance attract attention from both Lady Mary and Thomas Barrow. During a secret sexual encounter with Mary, Pamuk suffers a fatal heart attack. Mary, Anna Bates, and Cora then move his body back to his room to conceal the scandal from the household and visiting guests.

The secret does not stay buried. Daisy sees evidence of what happened, O'Brien pressures Edith into learning the story, and the rumour eventually spreads through London society. Sir Richard Carlisle later uses the information to control Mary and protect her reputation when their engagement begins to collapse.

The story was reportedly inspired by a real anecdote Julian Fellowes heard about a diplomat who died in a single woman's bedroom. Kemal Pamuk is played by Theo James; Evelyn Napier survives and is not the diplomat who dies.
