Early one quiet Monday morning, in an empty executive office, assistant Janice Denard begins to prepare for another ordinary day - but instead discovers evidence of horrific crimes, shocking photographs left abandoned in a printer. Now, with the help of the LVPD's computer forensics experts, the CSI team must track through hardware and software, deception and deceit to find the perpetrators. But while Willows and Stokes investigate the once well-hidden secrets now revealed in print, Grissom, Brown, and Sidle uncover new and disturbing evidence in a high-profile media case... the brutal murder of the Mayor's long-missing secretary.
