In 'The Collector', John Fowles explores the mind of a stalker who has the chance to make his fantasies come true. Throughout the novel, Frederick Clegg is likened to Caliban, from Shakespeare's 'The Tempest': stumbling ineptly after the object of his affections, and never managing to attract her or interest her. Winning some money gives Frederick the chance to kidnap and imprison Miranda, and we then see him attempt to fulfil his desires.
Frederick's character is both eerie and fascinating. There is a constant power struggle going on between him and Miranda. She is beautiful, well educated, confident, inspired, artistic - everything he is not, and although he is physically imprisoning her, he can't understand her. This frustrated desire to get inside her head undermines his capture of her, and at the same time, she is attempting to understand him, in order to be free. The relationship between the two characters is very well written, constantly changing and unpredictable.
Miranda, as the saner of the two, is easy to identify with, and yet the reader is also taken deeply inside Frederick's head as well. Again, it's an uneasy relationship between the reader and Frederick, as one hopefully doesn't support his actions(!), and yet the tone of his narration implies that the reader does. A very unsettling effect.
All in all, an excellent read, with an ending that will send shivers down your spine!
