Signed with the initials NRR, the telegram launches a race to uncover a treasure stolen by the Nazis and the truth about the murder of the last Russian royal family. All too soon, the treasure hunt starts to smell like a Lucian trap. But the bait might just be irresistible . . . what will Amy and Dan risk to find out what really happened on the night their parents died?
