Well, three stars sort of. Did I "like" The Woman in White? Meh. But I read it and, as long as this book is, that is a statement about its worth. You do not spend your lunch break for weeks reading something that doesn't somehow grab you unless you're trying to impress somebody or pass a class. As other reviewers have said, there's really nothing new here for those of us who read detective novels. You pretty much know what's going to happen from the beginning, but Collins writes it well enough to keep you moving through some occasionally weighty prose. 
 The Penguin Classics edition also has lots of informative stuff, both in the introduction and the appendices. My atrophied academician side enjoyed the footnotes, though had to sigh at some of the items they thought necessary to explain. Fifty years ago, I doubt the editors would have needed to include them.
