The punch lines are painful, the plot is shaky from rigor mortis, and it's doubtful that anyone will die laughing. They might grinace. The first of these two short (happily) novels is about one Charlie Davis, comic's comic and egotist's egotist who is first forced into the Communist party, turns counter-spy for the F.B.I. and ends up helping to expose the entire movement in America. The supposedly hilarious peaks range from his run-ins with Ina Borkman, ""Khrushchev in drag!,"" to a visit to ""Camp Comrade""--a training arena filled with leftist beatniks and students. The Swingers is Show busy business featuring Don Mason (Joey Adams), wife June (Cindy Adams), and a double murder/blackmail/heroin operation. The case is solved by ""Mickey Spane,"" friend and mystery writer. Perhaps Mickey Spane will reciprocate by featuring Joey Adamson in one of his books. . . as a corpse (he could die laughing). It somehow only seems fair.
