Picking up shortly after the events of 2005's Dance of Death, the book opens with the arrival of a package of fine dust at the Museum of Natural History; Diogenes has returned the diamonds he stole earlier. Meanwhile, Aloysius is in prison, having been framed for a number of murders. As his friends plot to spring him, his adversary lays the groundwork for a crowning criminal achievement. A mysterious benefactor funds the restoration of an ancient Egyptian tomb at the museum, but the work is beset by the mayhem Preston and Child's readers have come to expect—gory murders and suggestions of the supernatural. This entry, tying up many loose ends from its predecessors, is less likely to work as well for first-time readers, but followers of Aloysius Pendergast's previous exploits will find it a satisfying read with a tantalizing, ominous twist at the end.
