A DEADLY CONSPIRACY Graduate students Jonathan and Michael Rickner, sons of eminent archaeologist Sir William Rickner, are no strangers to historical mysteries and archaeological adventures.  But when Michael is discovered dead in his Washington, D.C. apartment, Jon refuses to believe the official ruling of suicide.  Digging deeper into his brother's work, he discovers evidence that Michael was murdered to keep his dissertation research buried. A DEVASTATING NATIONAL SECRET Joined by Michael's fiancée Mara Ellison, Jon travels to New York where he uncovers the threads of a deadly Depression-era conspiracy - one entangling the Hoover Administration, the Rockefellers, and the rise of Nazi Germany - and the elite cadre of assassins that still guard its unspeakable secret. THE LABYRINTHINE PATH TO THE TRUTH Finding themselves in the crosshairs of the same men who killed Michael, Jon and Mara must navigate a complex web of historical cover-ups and modern-day subterfuge, outwitting and outrunning their all-powerful pursuers as they race through the monuments and museums of Manhattan in a labyrinthine treasure hunt to discover the last secret of John D. Rockefeller, Jr.
