Bob Morane

The American government starts a series of experiments with the Pegasus, a spaceship that can also penetrate the fourth dimension. On the way back from a test flight, the Pegasus is misguided by Ylang Ylang and her secret organisation and lands in the Brazilian jungle. From there, a black light suddenly spreads across the earth, driving everyone crazy who comes into contact with it. Bob Morane, together with Bill and Sophia, sets off in search of the Pegasus, having to outrun Ylang Ylang and her men.
