Shaw brought a knife with her when she entered the head mistress’s office.
The small utility knife was hidden in her baggy school uniform, and its owner has already decided to stab the middle-aged woman in the chest.
The office was almost empty then, and no one would have heard a cry for help.
The teacher, who had abused Shaw for more than two years, said nothing but encouraged her to go on studying. The teacher was lucky enough to escape from death.
