Each book in the Crime Through Time series is hosted by a different child member of the famous Fitzmorgan detective family. While the young sleuth unravels a fictional mystery, readers learn about the real historical setting and actual crime-solving methods from the different eras. In sidebar activities, readers take on the role of assistant, helping to crack the case. Breathtakingly suspenseful but never violent and always age-appropriate, the books read like private investigative journals, with photos, maps, news clippings and crime scene sketches.

In book 6, set in 2031, Otis Fitzmorgan finds himself in the middle of an evil art fraud mystery in space. On his way back to earth via the new space elevator Otis is forced to use his outlawed private detective skills to get to the bottom of the mystery that is threatening to kill all of those on board.
