In this second half of the sixth book of the series, Marianne marries Sebastian, now a teaching fellow at the University and a consultant to the Ministry of Internal Security. Bianca requests Sebastian’s help when she gets victimized by a blackmailer. Sebastian and Basil lay a trap for the blackmailer/murderer, who escapes along a route Marianne traces. Threatened anew, Bianca again appeals to Sebastian, who duels and kills Dominic, a man who extorted credit from her. Marianne proves to Sebastian that she places unshakable trust in his word.
Basil and Sebastian reluctantly ask Marianne to infiltrate the headquarters of a radical group opposed to free trade, in hopes of preventing the highly placed criminal for whom the blackmailer/murderer works from blasting the fragile peace now existing between Gaea and Columbia. Will the daring infiltrator outfox the dangerous adversary who captures her? Will she succeed in her mission to find and transmit to Sebastian crucial evidence incriminating the plotters? And if she does, what effect will her feat produce in her marital relationship?
