Wow! Very intriguing premise! I really enjoy the Agent Pendergast series (this is the fifth in the series) and when you add Vicent D'Agosta into the mix, it's even better. The reading presentation by Rene Aubergonois is terrific. This is the first of the series I have done on audio and was not expecting to like it as well as the print versions but I thought it was actually enhanced by the audio presentation, though I do miss the print option of turning back to earlier pages to review previous clues. Does end in a cliffhanger so you will definitely want to go ahead and order the sequel Dance of Death before you finish Brimstone to find out what happens next! Also, since this is the first book of a trilogy arc, you may want to have the final book of the arc, Book of the Dead, on hand, too.
