It's been a brilliant year for thriller shows. Fans of the genre have been treated to some seriously binge-worthy series, from the Eddie Redmayne-starring spy epic, The Day of the Jackal, to Disney+'s political thriller Paradise and the gritty detective show, Dept. Q. 

But if, like me, you've already binge-watched all of those, you might be on the hunt for your next gripping thriller. Luckily, there's a new series coming to our screens very soon, and it's definitely going on my watchlist. Not only is the cast amazing, but the eight-parter is based on a bestselling novel about a mother whose young son goes missing from a playdate. 

If you liked Disney+'s The Stolen Girl, about a young girl who is abducted while at a school friend's house, then you'll like the sound of All Her Fault, which soon arrives on Sky and NOW.

Keep reading for all the details.

Sarah Snook leads the cast of the upcoming thriller

When Marissa turns up to collect her son, Milo, from a playdate with a new friend, she is horrified to discover the woman who answers the door is someone she doesn't recognise, and claims to have never heard of Milo. 

The synopsis continues: "As news of the disappearance ripples through the affluent community, time is of the essence to find Milo and an unexpected suspect is named – but as people become eager to find someone to blame, rumours and gossip about all the women involved start to grow.

Dakota Fanning also stars in the show

"Only one of them could have taken Milo – but might they all be at fault?"

The show is created by Megan Gallagher, who is known for her work on the gripping BBC thriller Wolf and Apple TV+'s Suspicion.
