Ace, New York, 1967, 1^st ed/paperback original.  G-663.  Based on the exciting MGM-Arena TV series.  MMPB, 158 pages.  Very good plus; tight binding; crease on front wrap at upper edge near spine; touch of edge wear.  Interior clean and unmarked with tanned pages.  Agents Napoleon Solo and Illya Kuryakin.  ‘It seemed incredible that an intelligent man like Dr. Richard Armden could turn violently against U.N.C.L.E. for no apparent reason.  Dr. Armden was a valued scientific advisor for U.N.C.L.E., but now he refused to have anything to do with the organization. …  Baffled, the two agents tried to question Dr. Armden’s colleagues in this small university town … and met with the same implacable hatred and threats from all of them.  It couldn’t be coincidence – THRUSH must have discovered a new method of winning over the minds of scientists to their cause.  But how did they do it?  And how could U.N.C.L.E. fight it?’ (from rear wrap)
