The Black Baroness — Dennis Wheatley

The Black Baroness is the third of seven volumes incorporating all the principal events which occurred between September, 1939, and May, 1945, covering the activities of Gregory Sallust, one of the most famous Secret Agents ever created in fiction about the Second World War.

Wheatley takes as his background the seventy terrific days from Hitler's invasion of Norway in April to the surrender of the French in June. Gregory Sallust once more plays his part in adventure after adventure in Scandinavia, the Low Countries and right through France; his adversary on this occasion being the Black Baroness, the French associate of his old enemy Herr Gruppenführer Grauber.
