Chief Inspector Brian Hooley has a plan, and it won't make him popular. He wants to bring back autistic detective Jonathan Roper. Currently suspended on misconduct charges, his condition, coupled with a relentless work ethic, makes Roper a unique investigator with observational skills that allow him to see what others miss. But he is also a complex man who doesn't get social boundaries, and plenty of his colleagues just don't like him. Hooley doesn't care about that. He knows Roper is the one to make a difference.

As an ex-DCI, Smith could have retired by now, and it is clear that some of his superiors wish that he would do so.

Malkie McCulloch resists pressure from his superiors to pass the case on to the road policing unit, convinced that whoever was behind the wheel will be waiting for the chance to finish the job.
