Diane Nine, president of Nine Speakers, a literary, speaking and film agency, said that book deals would depend on somebody's "relationship with Michael Jackson personally, and what they are willing to say."
"If somebody had a personal relationship and is willing to talk about things that nobody knows … there could be some good money in that," Nine said, adding that the payday could be from the low six figures to seven figures. "I think that if the nanny got a writer and was actually willing to do a tell-all, there could be a seven-figure advance in that."
It is hard to say where in the, say, $500,000 to $5 million range Rwaramba would fall. But any unseen photos or videos would certainly sweeten the payday.
Others might also try to profit off their stories.
Dr. Conrad Murray, who appears to have been in the room when Jackson went into cardiac arrest, could have an interesting and unique story to tell. But Dimond warns that his interaction might have been too short to really lead to a compelling book.
Then, there is the pop star's former wife Deborah Rowe, the mother of his two eldest children.
And an even more shocking story might come from the unknown surrogate mother of his youngest child, Prince Michael Jackson, II, also known as "Blanket."
Jackson's family could also share plenty of information about him, going back to the early days.
Finally, and the potentially most shocking, a book could come from one of the boys who have accused Jackson of child molestation. It is unclear what kind of confidentiality agreements were signed and how Jackson's death affects them.
Police Sgt. Steve Robel of the Santa Barbara County Sheriff's Department, who had investigated Jackson, might also have a story to tell, Dimond said, if he is willing to write about it.
"The tell-all book would, in hardcover, go right to the top of the best-seller list, because it would be promoting the scandal," said Richard Pine, an agent with InkWell Management, whose authors include James Patterson, Susan Orlean and Arianna Huffington.
Pine said such a tell-all book would have a hot week or two and almost no life as a paperback.
The real money, he said, would be to have a serious biographer tell the story of the pop legend. It wouldn't rocket to the top of the best-seller list, he said, but, "It would be enormous because it would be a combination of a top biographer who has the credibility of telling a good, fun story with the great subject matter."
He suggested that authors like Kitty Kelley or Tina Brown would be able to run away with a hot summer hit if they chose to write about Jackson.
In the immediate future, though, the big money is to be made by the republication of old books.
J. Randy Taraborrelli, who first published "Michael Jackson: The Magic and the Madness" in May 1991, just got a bump when his publisher, Macmillan, decided to reprint 85,000 copies of his book.
"He's probably working feverishly on a new forward and perhaps an epilogue to get that book out in a new edition as quickly as possible," Pine said. "I think publishers are going to be combing through their libraries to see what Michael Jackson books they have and see if it's going to make good economic sense to get them to republish."
