I know where all of them are. ”But I could find nothing, not one single word, about any giant strategic planning computer called Merlin!” Nevertheless the leading men of the planet didn't believe him.

Conn had known they'd never believe him, and so he had a trick or two up his space-trained sleeve that might outwit even their fabled Cosmic Computer ... if they dared accept his challenge.
