Rose Trevelyan is making quite a name for herself as an artist. After the success of her solo exhibition, she is commissioned to paint the portraits of two sisters in a remote farmhouse on Bodmin Moor.

But there’s something curious about the sisters . . .

With no partners or children between them, the sisters are on their own. They want their portraits painted ‘just for fun’, as there will be no one left to remember them when they’re gone.

Rose suspects there’s more to their story than they’re letting on.

At the same time, Rose is tutoring a talented young artist named Joel. She discovers he has ties to the sisters and her curiosity is aroused.

After some digging, Rose uncovers a devastating family secret stretching far into the past. Could one of the sisters be a killer?

Rose’s suspicions about the sisters were right, but she desperately wishes she was wrong.
