WEDNESDAY, SBS, 9.30PM
James Nesbitt’s (right) character in four-part drama The Secret is supposed to be a pillar of the community. But we can tell just by looking at him that he’s capable of all sorts of dastardly deeds. And so it proves, in this true story of an extramarital affair, between highly religious dentist Colin and Sunday school teacher Hazel (Genevieve O’Reilly), which has murderous consequences. Not wanting to consider divorce as it is strictly against their Baptist beliefs, but still wanting to be with each other instead of their respective spouses, Colin and Hazel sense an opportunity when his wife considers suicide after her father’s death.
