Marcia Clark was the lead prosecutor in what has been called the "trial of the century" -- the O.J. Simpson trial. Simpson was ultimately acquitted of the 1994 murders of ex-wife and her friend.
After the trial Marcia launched a new career as a writer.
Her new novel is called "Blood Defense," and it's about a hard-charging criminal defense attorney in Los Angeles.
In an interview with WGN Morning News Wednesday, Clark talked about what it's like watching the new popular television show about the trial, as well as what it was like to run into OJ.
