Cold Rage (Nick and Jacklyn, #5)

Even the best intentions have a blind side. In Richmond, Virginia, Deputy Mayor Dobson is brutally murdered. The FBI investigation reveals that this case isn't the only one in which an abusive husband died of unnatural causes. Special Agent Nicolas Hayes and his team begin the investigation but soon reach a dead end. There is no evidence and no suspect. When an old enemy appears on the scene, the investigation comes to a standstill, and Nicolas finds himself in mortal danger.
