Green Wing (2004)

Demented dwarf killers Joanna and Dr Statham are amazed that they seem to have got away with their hideous crime so consider themselves above the law. Caroline gets no fewer than three proposals. Sue gives birth to an infant with a mane just as impressive as Mac's. Mac gets some bad news while Martin (and we the viewer) ends up with a strange sense of déjà vu in the season's cliff-hanger ending.
