Edinburgh, March 1832. Kiera and Sebastian have been eagerly awaiting their bundle of joy, but trouble has been brewing in the form of the roguish criminal Bonnie Brock Kincaid. A new book and subsequent play features some of Kincaid's exploits, although he swears he had nothing to do with it. When the publisher is found brutally murdered - in an imitation of a gruesome scene - the finger not only points to Bonnie Brock as the possible culprit, but also the Gages, who have been outspoken in their condemnation of the tale. Now, the Gages are on a hunt to unmask the killer.
