Strangler's Wood (S02E02)

When Carla Constanza - the face of Brazil's leading cigarette brand for Monarch Tobacco - is found strangled in the infamous Strangler's Wood, DCI Barnaby and DS Troy not only find themselves investigating her murder, but three identical unsolved murders of innocent girls from eight years before. When Barnaby meets the other inhabitants of Midsomer Worthy he discovers more than one potential suspect - an ex-Detective Chief Inspector unhealthily obsessed with the original case; the creepy village landlord with a dark past and a sinister over-protective mother; the Managing Director of Monarch Tobacco, who stands to lose a lot of money and an au pair who knows more about Carla's death than she is letting on... As the murders mount up, Barnaby and Troy realise that time is running out. (Madman Entertainment)
