Twenty Years Later by Charlie Donlea

 Avery Mason is looking for a big story to start her news show next season.  She thinks that looking back at the 9-11 attack might be good, especially when she learns that new technology is letting scientists identify victims from small bone fragments.  She contacts the lead scientist who agrees to let her television crew come and film in the lab, using a recent victim who has been identified as the focus.  That victim was Victoria Ford.

But Avery finds that there is much more to this story than she had anticipated.  At the time of her death, Victoria Ford had been the main suspect in the sex murder of a famous author who was her married lover.  She was about to be indicted and was in the Towers that day to meet with a lawyer about her defense.  When Avery visits Victoria's sister, she is adamant that Victoria could never have killed anyone and plays Avery the voice message Victoria sent that day when she knew she wasn't going to make it out.  In that, she proclaimed her innocence and begged her sister to clear her name.

Avery decides this is definitely her story.  She contacts the detective who headed up the case, a former FBI agent.  He agrees to review the case with her and share case file documents but he has a secret and an ulterior motive.  That's understandable because Avery is hiding a big secret as well.  The two become involved and both try to hide their secrets while investigating the long ago murder.

This is my first Charlie Donlea novel but it won't be my last.  There are plenty of twists and turns.  Everyone has a big secret in their past and the slow reveal of these add to the plot.  The novel starts a bit slow but once it gets going is a mystery fan's pleasure.  This book is recommended for mystery readers.
