There's just one catch: the occupants must abide by his list of exacting rules. Jane starts to feel the house changing her in unexpected ways, but when she makes the shocking discovery about her predecessor Emma (Jessica Plummer), she's forced to confront unnerving similarities. As the two women's timelines interweave, Jane begins to question if her fate will be the same as the girl before.

But How many episodes of The Girl Before are there and when is it on television next? Here's everything you need to know.

The Girl Before is a four-part series airing on consecutive nights this week.

It made its debut on BBC One at 9pm on Sunday, December 19 and will continue to air every night at the same time until Wednesday, December 22.

The second instalment will kick off at 9pm on Monday, December 20 with episodes being made available on BBC iPlayer after they've broadcast.

Discussing how the series differs from the book and what viewers can expect over four episodes, creator, writer and executive producer JP Delaney said: "Plot wise, it's simpler because we cut out some of the twists and turns. But it's extraordinary because I came into it completely relaxed about changing things, but it has ended up being very similar as an overall plot.

"The main difference is that the book is very much within its genre – it’s a thriller and I really wanted to make it a page turner, so it's all about the plot and the pace.

"In TV, you have a chance to unpack people’s characters a bit more and I would say that the scripts are more nuanced and character-driven than the book is, which is quite unusual for TV programmes. That’s been one of the most fun things about doing it."
