The prototype of “Amelia”, the latest bomb created by the ingenious (and eccentric) scientist, Adolf Verybad, has been stolen. Zagor hunts for the thief (a spy in the pay of a foreign power) but the real resolutive intervention will be Chico’s!
While visiting the circus in Tiffin, just outside the Darkwood Forest, Zagor stumbles upon his friend Burnett, the town’s sheriff. Our hero is unwittingly involved in the investigation about Little Baby, a circus artiste unjustly accused of robbery...
Zagor and Chico meet an extraordinary individual at Fort Morgan: the French baron, Icaro La Plume, who for years has dreamed of building a vehicle capable of flying. But his attempts have always been frustrated. Even his latest flying machine, the ornitopter, crashes mysteriously to the ground. Having boarded an aerostat designed by La Plume by mistake, Chico is dragged away by the air currents until he ends up in the hands of the wicked One-Eyed Jack.
