I noticed on the dust covers that reviewers had compared the writer to Stephen King and Thomas Harris. Just ignore that, I suspect that they were looking for a comparison that they could not find. Alex North Is not really comparable to either though he exhibits a little of both. Rather you should just view him as a "Chiller" writer.
Initially disappointed with the tale, slow to start, no big intro, first chapter or tagline, the author was snagging you politely (perhaps because he is English rather than American) and over a couple of chapters the writer has you connected with the tale.
I will not tell you of the story (a spoiler) as if you are a fan of crime fiction then this is well worth a read. Neither a classic nor genre busting this novel is well worth a read. I would recommend it.
