The year is 1936. A coded message is received by British Intelligence and, in the absence of Colonel Granby, Bob Hardcastle heads to Innsbruck to have a secret meeting with a man named Berthold. Berthold is captured en route and when he shows up again, he is babbling insanely. What intel did he have and what made him go mad and what is the organization called the Eidelweiss, made up of 9 members dedicated to the preservation of Austrian nationalism? Granby has his work cut out for him.
