So, the characters are here, Aloysius and Vincent and Constance and the others. The pace is frenetic, and the scene shifts with almost every chapter. The plot is complex, answering some old questions and asking many more new ones. Sadly, though, the most important part is missing, the intangible something that singles out the aloof, mysterious Pendergast and makes him unique. The story may involve the love of Pendergast's life, but ironically the story has no heart. I started skimming early in the book, and never settled into the story at all, a first for this series.
As always, a great book, read it in 2 days.
