At the beginning of the week, former LAPD detective Greg Kading was a bundle of nerves.

As first reported by LA Weekly, he was putting his neck on the line Tuesday by self-publishing the book, Murder Rap, and revealing new evidence in the Tupac Shakur and Biggie Smalls murders that implicates entertainment mogul Sean Combs and Suge Knight in the process.

By the end of the week, Kading had a top 10 best seller in Amazon's music section and was buried under interview requests from some of the biggest names in show business, including the Today Show.

“It's great,” says Kading. “I'm just along for the ride.”

Tyson Cornell, Kading's publicist at Rare Bird Lit, says his phone hasn't stopped ringing over the past few days.

“It's insane here,” he says. “We're getting calls from all over the place, from radio shows I've never heard of to the Today show.”

Others on the list who have requested interviews, says Cornell, include the radio duo Mark and Brian, Good Day LA and MTV.

Cornell is also working to nail down the international market and says demand for the book has been particularly high in Germany and Spain.

“We anticipate a major blitz over the next 30 to 40 days,” says Cornell. “Right now there are dozens of people who want to do something with Greg.”

So far, says Kading, nearly all the feedback he's received concerning his book has been positive.

“Overall,” he says, “I'd say 90 percent of it has been very supportive and encouraging, but you do have elements of people who still want to believe Tupac is still alive or that it was all a government conspiracy. There's just the craziness that has always surrounded these cases, only now I'm knee-deep in it.”

Though the book has only been out for less than a week, Kading says he has not heard a peep since its release from families of Shakur or Wallace, nor has he heard from Combs or Knight.

Kading has, however, reached out to Keffe D and “Theresa Swann,” the two people Kading elicits confessions from and who point the finger toward Combs and Knight, respectively.

“When I informed Keffe D,” says Kading, “he obviously was concerned, but he said he's going to do what he's got to do.”

As for Swann, Kading says, “I did not speak with her directly, but I did ensure that she was notified through law enforcement about the release of the information in the book.”

Cornell says that Kading is looking forward to working on his next book, another autobiographical piece about a case he investigated.
