'Brotherly Love' is the seventh story from the internationally acclaimed series 'Cracker', winner of two BAFTA Awards, and created by the celebrated writer Jimmy McGovern. Fitz (Robbie Coltrane) is a brilliant Criminal Psychologist with a dark side - a side dependent on a cocktail of alcohol and gambling. He lectures at the local university and profiles suspects for the Manchester Police Force. The police believe they have solved the brutal murder of a prostitute when they arrest father of four, David Harvey (Mark Lambert), on strong circumstantial evidence. However, an identical murder while David is in custody means the team have to decide if they have the wrong man, or whether they are dealing with a copycat killer. Meanwhile the death of Fitz's mother drives him into the arms of his wife while Jimmy Beck (Lorcan Cranitch), recently returned from sick leave, finally breaks under the strain of work and his own guilt. When he takes the law to the limits he finds Penhaligon staring at him across an unbridgeable emotional chasm.
