Phillip Margolin, Lost Lake

In this mystery thriller, a young Portland attorney finds herself in the middle of a strange case after a man she had recently befriended violently attacks two men at her son's little league game. He claims he is part of a super-secret government group called the Unit. As events unfold, it turns out Morelli, is really Carl Rice, and he is wanted in connection with a number of brutal murders. But he tells a different tale, of killings that were part of his work with the unit. Margolin's book turns out to be a fun interweaving of plot lines, and he even makes what could be a rather tired plot about a supersecret government agency work, as doubt is case right up to the end about who is really telling the truth, and whether Morelli is really a secret government agent or just a delusional and psychopathic killer.
