There is a secret from our history - 500 years old - startling in its revelations and devastating in its political impact. A secret that has, thankfully, stayed hidden. Until now. Former Justice Department agent, Cotton Malone, travels to England and finds himself caught in a dark conspiracy born long ago, in the time of the Tudors. Now both the CIA and MI6 seem to be competing to uncover the mystery. For Malone, supposedly on holiday with his son Gary, the action comes thick and fast. When Gary disappears, Malone is forced into a race against time, as he battles to decipher a puzzle that leads him from the Middle Temple to the chapel at Windsor Castle, from an Oxford college to the sewers beneath Hampton Court. With assassins, traitors, spies, and dangerous disciples of a secret society closing in, Malone discovers that the solution to the mystery will not only draw him into a lethal trap, but force him closer to his own troubling past. And a shocking revelation.
