A year after wetting her pants during the university entrance exam, the young woman crouches behind a bush at the edge of the school oval, watching the library through binoculars. This year's calculus students are filing in and taking their seats while Mrs Hope holds the door open for them. She fights the urge to charge across the oval and choke the woman. She has waited a year. She can wait a few more minutes.
Time passes slowly. Finally the doors are closed, the students are seated and Mrs Hope hands out exam papers. The young woman pulls her balaclava down over her face. She shoulders her backpack and picks up her crossbow. Where she lives, it is illegal for civilians to own guns yet legal to own crossbows. She takes a final peak through the binoculars. Mrs Hope is seated, and the students are writing away furiously.
Letting the binoculars dangle from the strap round her neck, she bolts across the oval. She was a champion sprinter in her school's athletics team, and she hasn't lost her talent. She covers the distance to the library before any of the students, preoccupied with their exam, can notice her. She charges through the doors.
"NOBODY MOVE!"
Every hand stops writing; every head whips round to face her.
"I'm taking over! I'll be... officiating this exam. Mrs Hope!"
The teacher jumps.
"Come out here. Bring your chair with you."
The teacher emerges from behind the reception desk, pushing her castered chair ahead of her.
"I want you to sit in front of the class, in the centre."
Mrs Hope obeys.
The young woman produces a two-litre plastic bottle from her backpack and proffers it to the teacher. "Drink. All of it."
"What is it?"
"It's just water. Drink up." She neglects to mention that it is spiked with a diuretic.
Removing the cap, Mrs Hope raises the bottle to her mouth and tilts her head back. She gulps the water down until she gags. "I can't... I can't finish it."
"Why, you've still got more than half left. Come on!" She presses the crossbow bolt against the teacher's face. "Bottoms up!"
She raises the bottle to her lips and resumes drinking slowly, one belaboured swallow at a time. She lowers the bottle again when it is still one-third full. "I think I'm going to be sick."
The young woman takes the bottle from her. "Don't throw up. You can have a five-minute break." She turns to the students. "Okay, all of you, I want you to continue with your exam."
Everyone just keeps staring at her.
Pointing the crossbow at the student sitting nearest her, she screams, "All of you, heads down, pens in hand! Keep going on with the test!"
This time they oblige.
"Who are you?" Mrs Hope asks. "Do I know you?"
"No questions. We've got students trying to concentrate on an exam here." She glares down at the teacher, a thirty-something long-haired brunette in a grey business suit.
Mrs Hope cringes, unable to hold the young woman's gaze, and looks away.
There is silence. The young woman lets it continue for fifteen minutes.
"Here, time for another drink. And this time you'd better finish it! No excuses!"
Mrs Hope takes the bottle with trembling hands. She drinks at a more moderate pace this time and manages to finish.
