The three surviving children of Martin Luther King Jr. and Coretta Scott King continue to squabble over a $1.4 million book deal for her memoir. This week, according to the Associated Press, lawyers for Dexter King asked an Atlanta judge to demand that Bernice King — as administrator of her mother's estate — turn over personal papers, including love letters between the civil rights icons.

AP says the judge appointed a special master to catalogue dozens of boxes belonging to Coretta Scott King. Control of the documents threatens to derail a book deal with publisher Penguin Group. Bernice and Martin Luther King III say the book goes against their mother's wishes. And they say it exemplifies how Dexter has shut out them out of the corporation that controls their father's legacy.

I feel for the family members. But it would be a shame if a family fight kept us from learning learn more about this brave woman, who stood with her husband through the civil rights battles -- here they're shown in Montgomery, Ala. -- and then dedicated herself to his memory. Baltimore's Taylor Branch has ably detailed their relationship in his King books, but another view is always welcome.
