River of Secrets (A Wallace Hartman Mystery) - Roger Johns

A Baton Rouge congressman, infamous for changing his mind on hot-button issues, has been murdered in cold blood, his body posed to send a message. Now, Wallace Hartman has to figure out who’s sending that message. DNA evidence points to one man: Eddie Pitkin, a political activist who also happens to be the half-brother of Wallace’s childhood best friend. Murder seems like a leap for Eddie, who’s usual MO is posting viral videos of himself confronting politicians and religious leaders, but the evidence is strong, and Wallace makes the arrest. With the media in an uproar and supporters of Eddie’s protesting outside the police department, Wallace is charged with keeping all information about the investigation as tightly held as possible. But when it seems that someone inside the department is leaking information, and leaving threatening messages for Wallace’s loved ones, is there anyone left she can trust?
