Mark Lewis, a British lawyer who is representing several of the celebrities who fell victim to reporters and private investigators who hacked into their voicemail on behalf of Rupert Murdoch's newspapers in the U.K., has indicated that he may ask the FBI to step in to investigate possible criminal acts by those papers in the U.S. Lewis told Britain's Guardian newspaper that he plans to meet with his American associate, Norman Siegel, a former head of the New York Civil Liberties Union, to discuss strategy on pursuing lawsuits that they plan to file on behalf of three unnamed celebrities whose cellphones were allegedly hacked while they were on American SOiL. One of the three is reportedly a U.S. citizen. While three lawsuits seem like a minor matter compared with the hundreds that have been filed in the U.K., Lewis hinted that there were likely more to come. "You have to remember that the phone-hacking scandal in the U.K. began with just one case, and it grew exponentially," he said. Meanwhile, a book by British M.P. Tom Watson to be released on Thursday is expected to disclose additional wrongdoing by Murdoch and News Corp. Titled Dial M for Murdoch News Corporation and the Corruption of Britain , details of the book have been kept under tight wraps. According to the London Independent , even typesetters at publisher Penguin Books were required to sign confidentiality agreements. Watson, a member of the Commons Culture, Media and Sport Committee who led the questioning of Murdoch and son James at a committee hearing earlier this year, told the newspaper, "I have a hunch it will be one of the most attacked books this year."
