I'm not a fan of the crime writing genre, so I require more than some blood and guts and a few nasty frights to make me speak highly of a crime novel. Unfortunately, I cannot speak highly of From Potter's Field.I know more about dogs than I do about forensic medicine, so it makes me suspicious of the novel's factual integrity when I read that a murderer's eyes are "as pale blue as a malamute's", when in fact (according to the Alaskan Malamute Club of America), a malamute's eyes MUST be brown, never blue.It also made me laugh to think that all the crime agencies (and the media!!) in the USA would be completely ignorant regarding the closest relatives of the country's highest profile serial killer. Although if the good guys had known some basic details about the killer's family tree, Dr Kay would have been left twiddling her thumbs, so I suppose I should quit complaining.Well, I read the book right through to the end, and it kept me amused, so I have to give it one star.

After trying three different sizes,I still couldn't find one that fit. I first ordered a medium and it wouldn't even come close to hooking so I went up to size to xlarge which was waaay to big, my last possible option would be a large and it was still huge, wish I would have sent it back but was just tired of the whole process and kept it. The hooks are a pain as well and it is way over priced.....there is a zippered option on amazon that is much cheaper.

Negative

I was pretty disappointed when I purchased this book because I thought it was the next book in the series. Instead it is just a compilation of the previous 3 books one after another.
