Lethal - Sandra Brown

From a New York Times bestselling author, a young mother and a murder suspect must solve a corruption case while on the run from a dangerous manhunt.
Honor Gillette discovers Lee Coburn in her yard–the man accused of murdering seven people the night before. Dangerous, desperate, and armed, he promises Honor that she and her young daughter won't be hurt as long as she does everything he asks. Coburn claims that her beloved late husband possessed something extremely valuable: a treasure that places Honor and her daughter in grave danger. He's there to retrieve it at any cost.
From the FBI offices of Washington, D.C. to a rundown shrimp boat in coastal Louisiana, Coburn and Honor run from the very people sworn to protect them, unraveling a web of corruption that threatens to destroy them...and the fabric of society.
