Actually, Kelley, who grew up in the Philadelphia area, might be out to prove she doesn't have much to tell, at least about military affairs of the kind Gen. Petraeus allegedly indulged in with biographer Paula Broadwell.
Partly by hosting parties, the married Kelley became a kind of social ambassador for nearby MacDill Air Force Base and got to know high-ranking military officers, including Petraeus and his successor in Afghanistan, Gen. John Allen.
Reportedly, Broadwell suspected Kelley was putting the moves on both generals, and sent emails threatening Kelly and warning Allen about her.
Alarmed, Kelley took the threats to the FBI, whose investigation led to the married Petraeus acknowledging an affair and resigning from the CIA.
Numerous email exchanges between Kelley and Allen were also investigated, with some reports characterizing them as "inappropriate" and "flirtatious."
Allen's nomination to become NATO's supreme allied commander has since stalled, and early this week, Gen. Joseph Dunford assumed command of forces in Afghanistan.
The Post, quoting unnamed "friends" of Kelley's, said the book would be " 'payback' for the public humiliation she's suffered as a result of the scandal."
Late last month, Kelley proclaimed her innocence through her top Washington lawyer, Abbe Lowell.
All she and her suregon husband, Scott, did "to receive this attention was to let law enforcement know that they had been the subjects of inappropriate and potentially threatening behavior by someone else," Lowell said.
So, if there is a book, don't expect it to confess sins, but rather to profess innocence and possibly point fingers.
Kelley, born Jill Khawam, grew up with twin sister Natalie and two older siblings in Northeast Philadelphia, later moved to Huntingdon Valley, and still lived in the area as a young adult, according to reports.
Natalie, who got a graduate degree at Temple before becoming a lawyer, also got caught up in the scandal, with reports she sought Petraeus' help in a custody battle. Natalie Kelley even hired noted celebrity attorney Gloria Allred to help her deal with the media and supposed public misconceptions.
The twins' parents, who owned the Sahara restaurant for years in Voorhees, still live in Bucks County, according to the Philadelphia Inquirer.
