(From the publisher):
The Duke de Richleau and his friends had faced many dangers in Russia, Spain and Nazi Germany. Now a new and unexpected menace confronts them: one of their number, Rex Van Ryn is missing - and it seems he has taken with him more than a million dollars from the Buenos Aires branch of his family bank.
It soon becomes apparent that behind the conventional courtesy of Argentinian society lies a conspiracy of terror and silence - and a trail that leads straight to the Devil himself...
