Rennie is in Uruguay when his cousins discover a secret cache at their dead grandfather's cottage. Thousands of dollars in foreign currencies. A mystifying notebook. Multiple passports, some obviously fake. A gun. A disguise. And a photo of some Nazis. Rennie's mission: to find out whether there was more to the old man than anyone knew. Was he a spy? Did he help a Nazi war criminal escape justice? Rennie finds more questions than answers and more than one gun pointed in his direction.
