But then a second death occurs, this one even more shocking than the first, and quickly it becomes apparent that a terrible secret threatens to destroy the lives and reputations of several members of Dublin's elite.</P><P>Why did Victor Delahaye kill himself, and who is intent upon wreaking vengeance on so many of those who knew him?
