Not Fiendish at all, 30 Dec. 2013
If you are an experienced Sudoku fan, then don't bother with this book. The first handful of puzzles are hard-ish, but the degree of difficulty drops off considerably after that. By number 30 they are at a standard that can only be called easy. My wife has commandeered the book and is now finishing the puzzles at a rate of about 2-3 minutes each.
