A joke. That's what most cops think of me, an expert in Forensic Statement Analysis. I catch criminals by what they sayand, more important, what they don't. The science of language and double meanings fascinates me, and if that makes me a nerd at the police department, I can live with it. Even suffer the contempt of hot homicide cop Nate McCall. But an odd statement from one of Oklahoma City's finest has triggered my suspicionhis words ring of murder. And proving it could silence me forever.
