When Bytes Go Bad - Buck Slade - World Famous Private Investigator, #4

Someone very high up wants Buck involved in a case which has the Toronto Police force stumped. Three murders have occurred all of which look like accidents but a serial killer is sending e-mails to the police telling them he masterminded the homicides. Follow our hero and his team as they track a homicidal maniac who has as many computer skills as our hero, and possibly more. The hunt starts in Canada at a company called BLUE CORP and winds up in New York, BLUE CORP headquarters and a nearby elite research center which has developed an AI program capable of improving the bottom line of just about any company.
But behind the scenes, there are plans to use this program for less than laudable goals, like insider trading for one, and taking over the world for another. But not only is Buck on the case. It seems someone has hacked both Homeland Security and the NSA. Needless to say they're not very happy about it. Then a gang of terrorists gets thrown into the mix. Join Buck and the team for a wild romp through murder, corporate warfare, governmental ineptitude and a terrorist attack while it seems Bobby, our gamer accidentally transformed into a kangaroo in an earlier book, is viewed by many as ideal for grilling on the barbecue.
