Tainted Telepathy

Telepathy is too big a topic. We are familiar with telepathy from sf even if we will never experience it. I first heard of it as "tellypathy" while at school. I mention telepathy because the human heroine of SM Stirling's A Taint In The Blood converses telepathically with the Shadowspawn hero while asleep but does not remember the conversations when awake with the result that her captor, the mind-reading Shadowspawn villainess, neither detects nor suspects the occurrence of these conversations.

In Poul Anderson's "Journeys End," some human beings are telepathic. In Anderson's Technic History, some beings can detect and interpret brain emanations but Aycharaych is the only universal telepath.

I began to compile a list of other authors who have addressed the telepathy concept but it got too long. No doubt blog readers can think of some notable names.
