The robot stops for a moment, having found nothing.

She holds her breath, and the cloak of darkness in the stairwell falls like a curtain between them. She's so close she can hear him breathing. She can hear the pop in his shoulder when he rolls it. Can see the only light, shining from two floors above, glinting off the sclera of his eye.

That's when she moves. A whuff of air escapes her lungs as she bends over and grabs the robot, and she twists as if hoisting a gigantic discus at Mouse's face, with enough force to smash in a car window.
