Brain Twister

Someone is reading the minds of America's space scientists at a secret base in Nevada, and FBI agent Kenneth Malone must find out whom. The problem is that the only way to find a telepathic spy is with another telepath, but Malone discovers that all telepaths are crazy. His best chance seems to be a little old lady who thinks that she's Queen Elizabeth the first. Will Malone find the spy, or will this case prove to be a real brain twister?
