THEY TOLD THE POLICE IT WAS THE PERFECT SUMMER. THEY WERE LYING.

August, 1997. Matilda is killed in a tragic accident on the Dorset rocks, leaving her best friend Sophie alone, wracked with guilt.

Decades later, Sophie is back for the first time since that terrible summer, to sell her family's old beach hut and bury the memories forever.

But on clearing out the hut, she finds evidence that Matilda's death was no accident. What really happened the night she died?

As Sophie edges closer to the truth, the past starts to close in on the present.

Because the close-knit community is still home to a killer, and they want Sophie gone.
