Peter Rathbone

 was a member of the British Secret Service. He was tasked of getting any secrets the Triskele had. After the R101 had docked with the Triskele, he killed their lawgiver. In the ensuing chaos, he stole one of their guns, and planned to take it back to Britain to find out how to reproduce it. When the Eighth Doctor discovered this, he tried to stop Rathbone, but Rathbone fell from the R101 before it crashed into the French countryside. (AUDIO: Storm Warning)
