Those coffee tapes may have gotten President Clinton into hot water, but they're nothing compared with what the Diana interviews have done for Andrew Morton. The best-selling British author of “Diana, Her True Story” has been vilified in his country's press for publishing transcripts — featured in this week's People — of clandestine chats with the Princess herself. Now Morton is also in trouble with Mohamed Al Fayed, the owner of Harrods and father of Dodi. According to People Daily, the still-grieving Fayed has banned copies of Morton's updated biography of Diana from Harrods department store shelves. Accused of opportunism (he only revealed the existence of the interviews after the Princess' death), the groundbreaking author's stock seems to have sunk as low as that of the paparazzi.
