James Mycroft has just left for London to investigate a car accident similar to the one that killed his parents without saying good-bye to his partner in crime, Rachel Watts. Rachel is furious and worried about his strange behavior - not that Mycroft's ever exactly normal, but London is the scene of so many of his nightmares. Unable to resist, Rachel jumps on a plane to follow him and lands straight in a whole storm of trouble. The theft of a copy of Shakespeare's First Folio, the possible murder of a rare books conservator, and the deaths of Mycroft's parents.... Can Watts help Mycroft make sense of these events - or will she lose him forever?
