In Tenochtitlan, the capital of the Aztec Empire, 1480 a princess priestess vanishes from her room, but nothing is what it seems. The priest of death, Acati is called to investigate, but is horrified when he discovers his estranged brother, Neutemoc, a Jaguar Knight, is implicated in the presumed murder of the missing girl. Now Acati must investigate the situation and find out the truth ultimately to save his warrior brother from the penalty of death and to uncover the real murderer. But everywhere Acati turns, new secrets and leads are uncovered and nothing is what is seems on the surface. 
 Servant of the Underworld reads very similar to C. J. Sansom's medieval murder mysteries, with the exception that this is set in (well researched) Aztec times and has supernatural fantasy elements. I really enjoyed this book, and my only gripe is the very long Aztec names could be a little bit distracting. Other than that, this is a suspenseful tale and a very fast read for me, with plenty of cliffhangers to keep me turning the pages to reach the final resolution of this "whodunit" and "closed room" novel with a difference.
