I read The Blackhouse by the same author and I can thoroughly recommend it. My thoughts were 'this guy is no hack'. I came across 'I'll keep you safe' and thus expected a similar quality. I was sadly disappointed. I won't say too much here as I wouldn't want to prejudice anyone wishing to give it a try. I will just say that if you find the plot anywhere close to being plausible then you probably like fairy stories.
