I've been reading 'how to solve' books to help my brave, determined but limited proficiency. I turned to this one after having read others on the market and can see that this is the original, the template, for all those books dissecting clue types and devices and walking you through puzzles. As I understand it, 'Ximenes' is the first to write down basic rules of fair play in this cruel but amusing pass-time. That such rules are flouted and twisted by revered setters such as Araucaria matters not one jot. They are there and it is good to have them there, as reassuring (and as heeded) as UN weapons inspectors. The book is written with wit and panache, and you cringe before a towering intelligence (albeit a kind, fatherly one, who at times breaks his narrative to tell you to go and have a cup of tea or a lie down). The sections where the writer guides you through the creation of a relatively simple (Everyman) puzzle and those diabolical Azed things I won't even look at yet, are fascinating and illuminating. Order this book. It's worth the wait.
