"Has John Clooney’s friend and ally become a dangerous enemy?
Private investigator Anton Gruber has been CIA agent John Clooney’s trusted aid. Clooney may have questioned Gruber’s taste in cuisine, but never his loyalty – until Gruber double-crossed him.
Escaping with his life, Clooney is sidelined while his superior attempts to discover how Gruber was compromised. The investigation delves into Gruber’s astonishing past: from his unpleasant days as an East German border guard to life as a narcotics agent, from his time in the tango clubs of Buenos Aires to a trip up the Amazon in search of Nazi gold."
