During the dark days of Christian Inquisition in medieval Europe, a small group of telepaths is doing what it can to reduce the misery of the harassed populace.
Year is 1605. Speyer is a small town of scared & miserable people. Jonas, a telapath from this activist group, will contrive himself to be arrested as a wizard & tried in Speyer. But the Inquisitor, Herr Georg Knupf, himself is a potential telepath - though he doesn't know it. Jonas will make Knupf realize his hidden potential. A fundamentally honest telepathic Inquisitor, of course, doesn't convict people for being wizards & witches, since he can read their mind!
Told in a very entertaining way, sometimes bringing a smile.
