Together with Concord Police Chief Brian Hannon, Boston detective Joe Brindelli, and the FBI, Doc Adams investigates the KGB connection to a Boston high-tech research lab
Doc Adams series - Oral surgeon Charlie Adams' new adventure starts with the mysterious, painful death of an Adams cat. Then Doc's wife Mary is felled by a stranger fever caused, it is discovered, by a deadly pellet of irradiated thallium she found in the cat's body. Mary recovers, but the FBI is called in because the poison (``Moscow metal'') is used mostly in KGB assassinations and because an Adams neighbor, a refugee Hungarian scientist, has vanished. Soon Doc is involved with more deaths, double agents and the impending theft of a high-tech defense system. After some sleuthing, Doc engages in a lethal, climactic struggle with a fabled Soviet agent.
