This book by Jeffery Deaver sent chills down my spine, because it revealed how dangerous it could be if data, information, and knowledge fell into the wrong hands. In this Lincoln Rhyme novel, the famous detective took on a psychopath, who ‘knows everything’ by hacking into databases and using data mining – the business of the 21st century – to select victims and frame the innocents. He also attacked police officers and detectives by manipulating data, which is very effective in a world where people trust whatever got stored in the computers. Once again, Deaver put several twists in the story that kept me guessing who was the bad guy. Not surprisingly, I never got it right.
