... go the machines in the Ministry. They are busy now, in these days of ours. Quiet women hover over them. They nurse these machines. Feed them and oil them and keep them clean. And everyday, at around tea-time, they gather up the papers and bring them to the Man In The Office.
On one particular day, he was having a cup of tea and maybe a banana sandwich. Now it's rare that there would be anything outstanding in the papers (no "Wow" signals in this feed) but on this day he found something. He stopped eating (I'm almost certain it was a banana sandwich... yes. On white bread) and put a call to the Officer Across The River.
"Possible contact, repeat, possible contact, possible possible contact. I got a contact for you cats!" and hung up and went back to his sandwich.
Elsewhere, the Elephantine heard all of this and sharpened their game.
