A LANGUAGE expert from mid Wales may come face-to-face in court with Da Vinci Code novelist Dan Brown as the legal battle over the blockbuster erupts again. John Olsson had been set to testify at the previous trial alleging that the novel-ist lifted whole sections for his bestseller from books written by Lewis Perdue. But Mr Olsson, director of the Forensic Linguistics Institute in Llanfair Caereinion, near Welshpool, was never called. The trial judge ruled his evidence did not form part of the case, which Mr Perdue subsequently lost. Mr Perdue also went on to lose an appeal, leaving him with huge legal costs to pay. Now however, he plans to fight on and take the case to the Supreme Court in the hope it will order a retrial alleging Mr Brown plagiarised his books The Da Vinci Code Legacy and Daughter of God. If the appeal is granted, Mr Olsson's testimony will have to be considered by law. |
