W. Cregan

From Tardis Wiki, the free Doctor Who reference

W. Cregan, also known as Agent 37362, worked for the Universal Secret Service in 2067 and operated from London.

He once encountered a Dalek and was fully prepared for a battle with the alien until it said "Shake hands. Welcome." Unsure how to proceed, Cregan followed the Dalek's request although he came to heavily suspect that it was a spy. He later sent a photograph of the meeting to USS HQ. (PROSE: Friendly Dalek)
