Tight script, good direction, excellent performances, strong cast, effective use of locations....Paul McGann gives a detailed, subtle performance as the man in the centre of a new murder investigation who may just have committed a similar murder previously.There is an interesting moral emotional journey happening with his character (Ben Turner) and it intersects with the journey undertaken by Amanda Burton. Inevitably they cross over... Who has done what?The examination of WHY, both in the past and in the present, rather than WHO might have yielded a more interesting, Dostoyevskian story, but hey, who's complaining?
