If , like me, you momentarily feel the first of season 3 is not quite up to the standard of previous seasons, maintain the faith: the last season is the best of all. For those who haven't discovered this excellent show yet, you're really missing out.
Kerry Howard & Zoe Boyle star as 2 hapless witnesses caught in web of ineptitude and iniquity. Their chemistry is perfect, and they're strongly supported by an excellent cast (Samuel Anderson is especially good, and grows in his role.)
and a, sometimes macabrely, funny script.
