So, when he is approached by an affable ex-football star and told that he is just what the government is looking for to take part in a top-secret programme, he doesn't hesitate for too long.

But has he really been back in time? The portfolio of tintype photographs and sketches that he brings back convince the government. But all Si wants is to return . . .
