Pynchon mention in MK-ULTRA book

[Thomas Eckhardt]

"Mind control experiments, attempts to 'brainwash' human subjects, 
government efforts to create programmed killers, and other plots that 
emerged from MK-ULTRA appear in the works of writers as diverse as 
Thomas Pynchon, E. L. Doctorow, Joseph Heller and Ishmael Reed."

Stephen Kinzer, "Poisoner in Chief", 271-272.

Kinzer's book is an updated version of John Marks' indispensable "The 
Search of the Manchurian Candidate" with a focus on the fascinating 
figure of Dr. Sidney Gottlieb. Highly enjoyable -- if you are into this 
kind of thing.
