For the first time: the FBI thrillers Riptide and Hemlock Bay together in one volume. Catherine Coulter's FBI series "twists at every turn" ( San Diego Union-Tribune ). In two of her most gripping books- Riptide and Hemlock Bay - FBI agents Dillon Savich and Lacey Sherlock face dangerous threats in both their professional and personal lives. In Riptide , trouble follows an intrepid reporter to the quiet coastal Maine community, and Savich and Sherlock must face down a KGB agent to find the truth. In Hemlock Bay , the two travel to Maryland to take down the satanic child-killing Tuttle twins.
