Mare of Easttown hits our screens in April and with Oscar-winning star Kate Winslet playing the lead in her first TV appearance for a decade, it looks set to be an unmissable drama.

Winslet plays Detective Mare Sheehan, who must investigate the murder of a young girl over seven nerve-jangling episodes, yet this series is far more than a simple murder mystery. 

Here's everything we know about Mare of Easttown...

Mare of Easttown release date

The limited series will air weekly from Sunday 18 April on HBO Max in the US and Monday 19 April on Sky Atlantic and NOW TV in the UK. 

Mare of Easttown plot

The highly-anticipated TV series tells the story of Mare Sheehan, a detective in a small Pennsylvania town who's reluctantly known as "Ladyhawk" after making an impossible basketball shot in her youth. 

When she is assigned to investigate the murder of a young girl, the line between her personal life and professional duties soon begins to blur, and it’s not long before she finds herself struggling to stop her world from falling apart around her. 

But as well as being a "whodunnit" the series is an intriguing character portrait of a woman struggling with the death of her son. An official HBO synopsis describes the show as "an exploration into the dark side of a close community and an authentic examination of how family and past tragedies can define our present".
