Critics have tried to approach Pinter’s plays from a variety of changing perspectives, which emerge as a result of the playwright’s inventiveness. Pinter who aims at and achieves perhaps the most original innovations in dramatic form best exemplifies the range and diversity of the contemporary English drama. In consequence, he has created a distinctive personal style. Any attempt to make an exhaustive study of Harold Pinter at this stage would be futile; selection was inevitable. This dissertation will concentrate on eight plays by the playwright under discussion to demonstrate the refinement and development of his technique which was unprecedented and therefore shocked everybody in 1960s but is highly appreciated now.
