Four seemingly unrelated murders occur in various countries around the world. Mark Grant, a young, handsome FBI agent, is assigned to the case and soon finds out that all four men were employed by a “think tank.” As Mark delves deeper into the mysteries, he discovers the true purpose of the institutions and how just far their power reaches. Meanwhile, Diane Stevens and Kelly Harris, two gorgeous women who have been widowed by the think tank murders, find themselves thrown into danger and thrown together, however unwillingly, to protect themselves from the same unseen attackers who murdered their husbands. Each suspicious of the other, and both afraid for their lives, they team up for a life and death game of cat and mouse. As he has in each of his previous bestselling novels, Sidney Sheldon combines tough, witty characters and an intricate plot to deliver a compelling, suspenseful and powerful read.
