Well, well, well...you didn't do so well guessing this one, Micky. It's been a while since I've felt so needy for answers and so unsure what was really going on in a thriller. I enjoyed the ride immensely.

This thriller had two unreliable narrators and they're the only narrators we had (laughs maniacally). The story centred around a missing wife, presumed dead and the grieving author husband who is offered a quiet writing spot on a highland island. This island was creepy, cliquey with a very evasive and close-knit community. It felt immediately like once Grady (the husband) arrived, he would never be able to get off the island. No one would share the ferry timetable, the phones weren't working, no internet and no transport.

Columbo the dog was Grady's loyal companion and a bright spot of joy. Grady then spent time writing a book (there's a lot to that element that was intriguing) and once he finished his book, things got even more weird. I'll say no more to the plot but it was wild and gripping.

The occasional POV from the missing wife in a timeline before her disappearance added massively to the intrigue but the answers always felt behind a foggy window and just out of grasp. The ending was satisfying, I didn't see the later twists coming and it stayed ominous and somewhat creepy.

I have to mention a gripe I had about an inconsistency in this book (or lack of research) in relation to the geographical setting. It's a small thing but it really bugged me. This highland island was called Amberley. If you take the time to look at a map of the the west coast of Scotland, you will see not one island that has an Anglicised name. Not. One. Amberley sounds like something of the south coast of England or in the Channel Islands. Just rather irritating.

Overall, a hugely enjoyable thriller that I really recommend.
