Following a lead of Trench's, the three heroes head to Bjorland, where they again find Cyber, who offers Trench a fortune to betray his allies. Trench takes the treasure Cyber offered and runs, leaving Diana and Ching to fight off Cyber's falcons. As the villainess escapes, they are joined by Reginald Hyde-Whyte who tends to their wounds and takes them to London where Diana loses herself in Carnaby Street and thoughts of romance, while Ching avoids another attempt on his life.
