Neil Cross has been nominated for the Booker Prize and won an Emmy for his popular BBC TV series, Luther. Here fans get a glimpse of Detective John Luther before he cracked - when he was simply a tormented, borderline genius whose thirst for justice sometimes took him beyond the limits of the law. The case that pushes him to murder, however, will rend both his personal and professional lives asunder, and leave in its wake a shattered man who may never recover.
