Did Someone Call for Spooks?

Spy Ghost, by Norman Daniels (Pyramid, 1965). This is the third book in Daniels’ series starring John Keith, a James Bond-like agent of A.P.E. (the American Policy Executive), “an ultrasecret organization, known only to a handful, that doesn’t officially exist but which nevertheless employs agents around the world to take care of any job too beyond the traditional agencies.” Cover
