Adultery is TV drama by numbers – and I’m hooked

The unequivocally titled Adultery began with a somewhat portentous voiceover. ‘There is a psychological equation,’ it intoned. ‘Attraction plus an obstacle equals excitement. But what happens if the attraction is too strong and the obstacles are too great? Do you threaten everything?’ The answer to the latter question would turn out to be a firm ‘yes’ – but first, the show had to get the adulterers together: something it did with commendable efficiency. Following one of those familiar scenes of everyday family chaos, harassed mum Beth set off on yet another errand for her teenage son Ollie and knocked a hunky bloke off his bike with her car.
