Lethal

Lethal by Sandra Brown

From the Goodreads website: "When her four year old daughter informs her a sick man is in their yard, Honor Gillette rushes out to help him. But that "sick" man turns out to be Lee Coburn, the man accused of murdering seven people the night before. Dangerous, desperate, and armed, he promises Honor that she and her daughter won't be hurt as long as she does everything he asks. She has no choice but to accept him at his word.

But Honor soon discovers that even those close to her can't be trusted. Coburn claims that her beloved late husband possessed something extremely valuable that places Honor and her daughter in grave danger. Coburn is there to retrieve it -- at any cost. From FBI offices in Washington, D.C., to a rundown shrimp boat in coastal Louisiana, Coburn and Honor run for their lives from the very people sworn to protect them, and unravel a web of corruption and depravity that threatens not only them, but the fabric of our society.

I really enjoyed this book.  I  figured out who the baddest bad guy was, but I kept waiting for a double cross. I'm not going to say how it all turned out.
