According to Jo Nesbo, the Norwegian crime writer, the only thing missing in our appreciation of history is a place for the imagination to work its magic and offer us possible what-if scenarios that could save us from ourselves. For instance, what would happen if technology in the form of a crazy, wacky invention such as a flying bathtub suddenly became available that allowed us to move back and forth in time to change the less favourable outcomes of history? While the notion of time-travel is not original, how Nesbo uses it is: his cast of participants in this hilarious tale of historical manoeuvring includes an eccentric old inventor who has the knack to create the most unusual devices that only children seem to enjoy and make use of: fart powder, high-octane soap, a bathtub that serves as a time machine, etcetera, etcetera. As Lisa and Nilly, two Norwegian youngsters who are eagerly seeking adventure, team up with the curiously reclusive Dr. Proctor, a whole new world of intrigue and whim opens up for them as they battle the forces of evil for control of history. Their crusade will take them to Paris to fight a crime boss who believes he is answerable to nobody. With the help of this magical contraption, the children will launch out into nine hundred years of history to put a string of injustices right that have never been completely addressed or understood. While they might save a lot of lives by changing the finer detail of events such as the burning of Joan d'Arc, the Battle of Waterloo, and the Reign of Terror before they happen, there are some things that can't be radically changed, only made better. Solutions to big problems start with child-like imaginations seeing all kinds of possibilities, including the far-fetched, and trying to make them work, such as getting Dr. Proctor and his sweetheart to tie the knot. Adults, on the other hand, are trapped in a world that is humourless, deadly serious, and often instinctual. As one of those sober adults who needs to periodically lighten up, I really enjoyed this children's story because it was genuinely funny and absurd. Great for the kid in all of us!
