Book excerpt: This issue, we have an original mystery from Mike Adamson, plus a recent tale by Neil S. Plakcy (courtesy of our Acquiring Editors). Classic mystery reprints come from Dale Clark and Edgar Wallace. Plus, of course, a solve-it-yourself puzzler by Hal Charles. I broke out the Adventure category for Vera Shamarin, by William Murray Graydon. It’s an exciting tale of escape from Russia. Not really mystery, but perhaps more suspense, I thought it belonged in its own category. See if you agree. It’s an all-classic lineup from our science fiction writers: Ted White & Marion Zimmer Bradley lead off, followed by Frank Belknap Long, Ivar Jorgenson, and Edmond Hamilton. Jack Sharkey’s short novel, “The Programmed People,” caps things off.
