WHO: @commissionerknight WHERE: New Scotland Yard
It's been a few years since Ender's had his own workspace at New Scotland Yard, but it's as familiar as ever: officers from his own command stationed at the doors, civilians and plainclothes detectives breaking up the sea of uniforms as people bustle from place to place; overhearing snippets of dozens of conversations as he makes his way toward the commissioner's office. He's not sure what this meeting's about, but that's not unusual--given the nature of his command, it's often safest not to put certain information in writing.
So, as he identifies himself to the office staff and gains approval to enter, there's no reason to suspect that anything's wrong. Knocking on the commissioner's door, he says, "Sir? You wanted to see me?"
