But now I do. 'Sara. I can read you like a book.' I say smugly, as for a few moments Sara's mouth drops open, revealing her braced yellow teeth. 'Not so perfect now, are you?' I laugh. But my laughter turns to horror. She produces a long curved rusty knife, dripping with blood. I gasp quietly. 'Who has had the last laugh now eh Saskia?'She throws her head back, cackling with bloodthirsty laughter. At that moment, I spin the kinfe out of her hand and throw it out of the window. She slaps me hard and says 'No worries, I have a Plan B.' She reaches into her pocket and brings out a huge red button. 'Press this,' She says,'And you and I will be gone forever.' I bite my lip. I must keep her talking while I think of a plan to get out of here. But I don't need to. Sirens are heard and Sara's eyes widen. She musn't have been expecting this. She jumps out the back window, running until I've lost sight of her. 'Phew...' I say. She's gone and she won't come back.
