Barking!

Mild-mannered Stuart Roberts suffers from nightmares where he remembers committing a murder (possibly two) and wants to know, could this be true? Grace doesn't want to take the case on the grounds that murders tend to mean there's killer around somewhere and she'd rather pass - thanks very much.
But these are killings with a difference: they took place nearly thirty years before Stuart was born.
Despite her scepticism Grace has never been able to resist the lure of an unlimited expense account, so she takes the job, blissfully unaware that her life is about to be invaded by an ageing rock star, a flatulent bulldog and a voice from the past. And then she discovers that her client isn't quite what he appears to be.
