The Secret of Crickley Hall writer Joe Ahearne will write and direct a chilling new mini-series for BBC One next year.

The Replacement will examine the darker side of working women, motherhood and the issues that arise from making “the right choice”.

Joe Ahearne has previously written episodes of Da Vinci’s Demons, This Life and Ultraviolet.

The official synopsis for The Replacement reads: “When Ellen, a successful architect in her mid-thirties, falls pregnant, she finds maternity cover in Paula: brilliant, enthusiastic and raring to go. Ellen wants to champion her, but something’s not right. Ellen begins to fear for her safety when she suspects her maternity cover has a disturbing agenda. Can her suspicions be explained away as female rivalry and her own insecurity of opting out of work at the top of her game… or do they speak to something deeper?”

The three 60-minute episodes will begin filming in early summer 2016 in Scotland.
