Turing Hopper is an Artificial Intelligence Personality with a mind like Miss Marple and hardware that hides a suspiciously human heart.

Of course, it's hard to do legwork without legs, so when her human colleague Ray is murdered, she'll have to think fast and rely on the help of her friends. But when the almost-sentient mainframe-sleuth recognizes an enemy within the walls of her lab, she realizes that whatever was after Ray might well have her on its hit list, too.
