Once again Kemlo and his friends find themselves in the thick of a plot – a plot to overthrow the complete organisation of the Satellite. And they are not up against anything they can understand.
These mysterious black-suited men who are not men, but who can do with the utmost efficiency anything they are told, cause considerable, and not unwarranted, alarm on Satellite K.
‘Zombies’ is Krillie’s name for them – although Kemlo and Kerowski explain that the men engaged in the Sonic Wave Experiment are risking their lives in the attempt to revolutionise man’s powers of communication through space.
Yet even the leader of the Space Scouts and his friends are shaken at the odd behaviour of some of the S.W.V.s under text conditions thousands of miles out in space. Perhaps after all there are stronger forces at work than the earth scientists had anticipated. Kemlo is determined to find out.
But they have another problem as well. What is the mysterious weakness which haunts Alvin Searle, the stern and dominating figure in charge of the experiment – and can the space-born boys help him overcome it?
Solid land inside a cloud of ‘star dust’ – where no solid land should be. And the weird voices – where are they coming from?
Forced down on a minor star galaxy, Kemlo and his friends of Satellite Belt K discover a secret of Space which gives scientists information for which they have been searching for years.
