Lord Thomas Chamberlain is a British royal serviceman that works in the Syldavian Court. he appears in King Ottokar's Sceptre in The Adventures of Tintin series. He was first seen at Kropow Castle with Alfred Alembick to photograph some documents whenever authority that Alembick may permit to. When Tintin and the King came for the Ottokar Sceptre, they were too late. Chamberlain hired Thompson and Thomson to find out the scepter is missing and why. Then, he's at the day with the King and the loyalists at St. Vladimir's Day where he could be worried that someone might be the ruler, and Tintin and the two detectives had found the scepter and Muskar XII had continued being the king.
