Even if you're the type who normally shuns strategy guides and prefers to do it all on your own, this is a handy book to have. The intricacies of SPQR can get so complex that you'll be glad to have a clear guide to the plot line and story elements--let alone the puzzles. Best of all, the book is arranged so that it can be used as a reference, or as a source of subtle hints, or as a solution book--you get just the level of help you want.
