Season 8 of everyone's favourite psychopath-chasing police-procedural starring a wealth of talented and beautiful cops and brainiacs returns to Irish screens tonight with not only a whole new set of crimes to be solved but also a brand new member of the team. Jeanne Tripplehorn plays Alex Blake, and while she may not be the Emily you knew and loved, you'll soon warm to her as the team track down a serial killer called 'The Silencer', so-named thanks to his lovely sowing closed of his victims mouths. Same old same old, eh?
