Drop By Drop

Are the Russians working with the CIA to influence the next presidential election? It falls to Professor Sam Rockman to find out. He has come to Washington to serve his country and recover from the death of his wife. But what he discovers is danger and betrayal. Secret documents are showing up on his doorstep. Someone tries to poison him on a trip to Russia. Someone else is strewing nuclear materials up and down Interstate 95. Sam finds allies among a savvy Kentucky senator, a billionaire investment banker, his wife’s old rabbi, the president’s national security advisor, and the whip-smart Senate staffer Cecilia Plant. Can they be trusted? Can anyone?
