Once studied by British intelligence for his excruciating sensitivity to the world's turmoil, Bennett Grey has withdrawn from the world - until an American Bureau of Investigation agent comes to assess Grey's potential as a weapon in a new kind of warfare. Agent Harris Stuyvesant needs Grey's help to enter a realm where the rich and the radical exist side by side - a heady mix of power, celebrity, and sexuality that conceals the free world's deadliest enemy. Soon Stuyvesant finds himself dangerously seduced by one woman and - even more dangerously - falling in love with another. As he sifts through secrets divulged and kept, he uncovers the target of a horrifying conspiracy, and wonders if he can trust anyone, even his touchstone.
