Ten inventive variations on the old problem of First Contact, these include Eric Frank Russell's touching Dear Devil, where an unsightly but gentle poet arrives to help Earth's children after a nuclear holocaust; Randall Garrett's sprightly The Best Policy, in which a man beats an alien lie-detector by looking at the truth from a number of angles; Asimov's much reprinted The Gentle Vultures which offers an interesting speculation on UFO's, and Damon Knight's Stranger Station demonstrates the outcome when true love meets sheer hate. Some of the best.
