This sequel to Brimstone is better than the first part of the trilogy. In fact, I think you can pretty much read it on its own without previously reading the first part.
The twists are non-stop, and the body count adds up quickly. Diogenes is a very capable villain who competently matches wits with his brother, Agent Aloysius Pendergast. Of course, Pendergast gets the final laugh...or does he? If the the third installment is anything like Dance of Death, it stands to be another all out battle between the brothers Pendergast. A battle in which you can't predict who's body will be left behind.
