Two more episodes of the gritty drama starring Ken Stott as the eponymous detective. In 'The Black Book', the body of a missing prostitute is found, and the circumstances recall an unsolved murder from twenty years before. Rebus is convinced that the prime suspect from the earlier case has struck again. In 'A Question of Blood', Rebus investigates a shooting at Stoneymount College that has left two pupils and an instructor dead, and another boy seriously injured. The evidence implicates one of the deceased - but Rebus has other ideas.
