I rate this one a bit lower than the first volume (which introduced me to Dr. Thorndyke.)  The second set of short stories in this volume do not have the good doctor or other relevant characters in them.  They are good stories, but, alas, no Thorndyke.  Nor do I believe that Helen Vardon's Confession is that good a novel (and I know I am in the minority here.)  Nevertheless, the stories are, in the whole, excellent examples of Edwardian CSI.
