It's been a while since I read anything as plot driven as this, I used to read quite a few "domestic thrillers" but after a while they got samey/predictable so I stopped. I was drawn to this one as I liked the idea of the remote Scottish island setting and the mysterious piece of art (and enigmatic artist) at the centre of it all. I thought the characters were generally well-drawn and multi-layered. Generally I was keen to pick this book up, though the plot ebbed and flowed a bit, feeling very slow at times. I really liked the inclusion of Vanessa's diary, and the letters and emails which appeared. Overall - an enjoyable read, but it hasn't inspired me to read more thrillers.

Potential spoiler-y thoughts:

I didn't love the ending, I wanted Becker to escape or be found! I enjoyed the "evolution" of Grace and liked her as a villain! I wanted to know more about why Sebastian was so keen to stay friends with/employ Becker after what happened with Helena, and I don't think we ever really understood why Vanessa left everything to Douglas, other than to spite Emmeline? I felt we were left with a few loose ends tbh
