His desk was clear apart from the checklist and the pen set neatly to one side.
He sat calmly in the quiet of the office, his hands in his lap, fingers loosely interlinked, and waited.
Not long now, she'll be here soon, he thought. She can't stand the monthly figures being late. She'll be down any minute. Some more bullying, more shouting. Intolerable. And for what? The pittance I get for the hours I put in.
Soon the sound of footsteps on the stairs. The handle turned. The door opened. A strident step. A flash of those steel-grey eyes. The start of a sneer. An intake of breath.
He slid the drawer open, pulled out the silenced gun, shot her just once between the eyes.
He picked up the pen, ticked off the last item on the checklist, returned the gun to the drawer, closed and locked it, made his way across the office, turned for one last look and left, closing the door quietly behind him.
