THE OTHER MINISTER
It was nearing midnight and the Prime Minister was sitting
alone in his office, reading a long memo that was slipping

President of a far distant country, and between
wondering when the wretched man would telephone, and
trying to suppress unpleasant memories of what had
been a very long, tiring, and difficult week, there was not
much space in his head for anything else. The more he
attempted to focus on the print on the page before him,
the more clearly the Prime Minister could see the gloating
face of one of his political opponents. This particular
opponent had appeared on the news that very day, not
only to enumerate all the terrible things that had
happened in the last week (as though anyone needed
reminding) but also to explain why each and every one of
them was the government's fault.
