Patterson solves a ten year old case and Supt. Tilley awards him a commendation. Eddie Patterson, Jim's twin brother visiting from Sydney, is somewhat crazy and nearly always drunk, and is seen by Supt. Tilley at a lively evening at a club. When Tilley meets Patterson, he mistakes Jim for Eddie, and is aghast at his behaviour. Further reports reach Homicide about Eddie, and they become concerned about Jim's 'split personality'.
