Shade Vassily

Lord Wyse was a regular resident of the Imperial Club who enjoyed a game of chess. The Ninth Doctor and Rose Tyler enjoyed his company and found that a local black cat was fond of him too. He helped find the two travellers a room in the club and often played a game of chess with the Doctor.

During a raid, he was inclined to leaving the club to play with a friend, which he always seemed to do on a Wednesday night. After Rose followed the black cat to the clocktower of London, she found Wyse who told her everything, about his involvement in the massacre of many innocent people and how he disguised himself until he was able to reach his ship and take off again. He was Shade Vassily. (PROSE:  The Clockwise Man)
