Have you ever wondered what happens to Spies when they retire.
I have a strong suspicion that this lot are all retired MI5 agents. They just have that look about them. Nothing in the town centre moves without them noticing. They look poised to close in on any subversive elements in the shopping centre and quickly take them out or circulation.
However I don't think they have noticed former KGB boss Boris lurking in the background..... Just watch he doesn't slip deadly poison in your tea guys.
