Rebus is juggling four cases trying to nail one killer - who might just lead back to the infamous Bible John. And he"s doing it under the scrutiny of an internal inquiry led by a man he has just accused of taking backhanders from Glasgow"s Mr Big. As if this wasn"t enough, there are TV cameras at his back investigating a miscarriage of justice, making Rebus a criminal in the eyes of a million or more viewers. Just one mistake is likely to mean an unpleasant and not particularly speedy death or, worse still, losing his job.
