“Normally a workaholic techie, Zack has missed work for several days. So his friend, Turing, does the only neighborly thing and checks to see if Zack has logged in from home. No luck. Then she skims the databases of local banks to find his personal identification number. Nothing. Next she searches police and hospital records throughout the state. No Zack.” Turing is no crazed stalker: she is an artificial intelligence personality of Zack’s creation. But, unlike other AIPs, Turing is sentient – and she senses foul play. Fortunately, when Zack created her, he downloaded into Turing every murder mystery in his library, so Turing would think like a detective. She does find some clues to Zack’s disappearance, but the enemies may well lie in the real world – where Turing has no ability to move.
