I tried a few of the other fly fishing mystery book series, but didn't like them. So I was pleasantly surprised when I read "The Royal Wulff Murders" and enjoyed it as much as I did. I would definitely agree with the above and recommend this book. I haven't read the "The Gray Ghost Murders" yet, but it's on my list.
