It started off like a scene from some sort of spy movie.
A freezing February day. A vast derelict and abandoned industrial hulk of a building. Inside a small security hut on the outskirts of the complex, an unlikely combination of characters huddled around a small heater, it struggling to keep the cold at bay.
Within a few minutes a car arrives and sweeps into the vast concrete wasteland that surrounds the old power plant, perhaps setting the scene for an exchange of secret documents, or the passing on of the results of some espionage operation.
