Every so often there is a ‘cybersleuthing’ story that catches my attention and winds up being worth the effort. This story is not one of those. basically Cornwell seems to not have been able to decide whether to make this a computer crime story -- grisly murder photos were sent to the medical examiner via email -- or an epidemic/contagion thriller -- one of the victims has a disease that looks a lot like smallpox. The end result is weak in both areas. The computer/Internet descriptions are laughable, and the contagion factor is too easily wrapped up to be too captivating. I need to stop reading mysteries.
