The Silent Wife by Karin Slaughter
Georgia Bureau of Investigations agent Will Trent is called to investigate the death of an inmate during a prison riot. The inmate had claimed that he was innocent of his crime, and that he had been framed by Jeffrey Tolliver and Grant County law enforcement officials. Will feels boxed in, as Tolliver is the late husband of Sara Linton, the woman Will hopes to marry. There’s a serial rapist and murderer on the loose, and Will believes that there is a connection to the ten year old crime that Tolliver was involved in. Will is a believable character, someone who was raised in the foster system and struggles with dyslexia. Sara is a doctor and former medical examiner, but isn’t a perfect person. She and Will butt heads and argue about their future and about the case. Slaughter’s books guarantee that that you will be up until the wee hours, and who could ask for more?
