Viewers chilled to the bone by The Replacement

The Replacement has gripped the nation – and now The Mail on Sunday can reveal how its thrills are inspired by the great British director behind masterpieces including Psycho and The Birds.

With its nerve-tingling plot twists – and a shocking conclusion to the first episode – The Replacement has gripped the nation, particularly the female half.

The BBC1 drama, tipped to be one of the stand-out series of the year, tackles one of the taboos of the workplace – the professional fear that stalks so many expectant mothers.

Last week’s opening episode saw high-flying architect Ellen Rooney, played by Morven Christie, become pregnant while on the verge of a breakthrough promotion as a partner at her firm.

SO WHAT’S THE TRUTH BEHIND LAST WEEK’S SHATTERING FINALE?
