Brain Twister

Brain Twister is a science fiction novel by Randal Garrett and Laurence M. Janifer under the pen-name of ”Mark Phillips”, first published under the title That Sweet Little Old Lady in 1959. This is the book edition, published in 1962. It was nominated for the Hugo Award in 1960.

In the not too distant future, Ken Malone, young but promising FBI agent, is given the most important and difficult assignment of his career: find a spy who is stealing information from the Ultra Top Absolute Secret project to develop a non-rocket space ship at Yucca Flats Labs in Nevada.

But this is not a normal spy, this spy laughs at the FBI and all attempts to find him or her because they use an unknown new method to steal the information directly from the minds of the scientists.

And then of course, there is the Sweet Little Old Lady who is immortal and the stunning nurse and the Las Vegas gangsters and ... well, you had better listen to the story to find out the details.

His first problem: how do you find a telepath to catch the first telepath?

Brain Twister is the first part of their ”Psi-Power series”. The first story they wrote in the series was That Sweet Little Old Lady, published in the Sept./Oct. 1959 edition of Analog Science Fiction and Science Fact and published in book-form as Brain Twister in 1962. Subsequent stories include The Impossibles (first published as Out Like a Light in Analog, April/May/June 1960), and Supermind (first published as Occasion for Disaster in Analog, November/December 1960 and January/February 1961.

This series is one of the highlights of 1960s SF, and still highly recommended.
