From the publisher: It's New Year's Eve, December 31, 1999, and Washington, D.C., is under siege. Early in the day, a grisly machine gun attack in the Dupont Circle Metro station leaves dozens dead and the city crippled with fear. A note delivered to the mayor's office pins the massacre on the Digger, a robot like assassin programmed to wreak havoc on the capital every four hours - until midnight. Only a ransom of $20 million delivered to the Digger's accomplice - and mastermind - will end the death and terror. But the Digger becomes a far more sinister threat when his accomplice is killed in a freak accident while en route to the money drop. With the ransom note as the single scrap of evidence, Special Agent Margaret Lukas calls upon Parker Kincaid, a retired FBI agent and the top forensic document examiner in the country. Somehow, by midnight, they must find the Digger - before he finds them."
My thoughts: I've read several of Deaver's books and always come away feeling I've read a good book. This was no exception. Through a couple of twists and turns this keeps you on the edge of your seat all the way through. I even felt a sorry for the Digger, but you'll have to read it to find out why.
