Jack Dwyer, likable ex-cop, would-be actor (Rough Cut, etc.), is eking out a meager income as a security guard at Channel 3 when, David Curtis, their star newscaster, dies, on the air, of cyanide poisoning. Dwyer, who had earlier chased and lost an intruder in the building, gets fired and decides to do some sleuthing on his own. It leads him to a connection with nearby Falworthy House, a halfway station for troubled teen-agers--one of whom killed himself after being interviewed several times in a Channel 3 series on teen-age suicide. Meanwhile, the intruder, Mitch Tomlin, also living at Falworthy House, is arrested for Curtis' murder, but Dwyer keeps right on probing, sensing that the twitchy staff at Channel 3 are up to no good. Good-looking news consultant Kelly Ford, mistress of lame, arrogant station-owner Robert Fitzgerald; has been newsman Dev Robards; rough, tough sportscaster Mike Perry--they all have something to hide. There's also a menancing pair of Guccishod twins in the background and some lethal tapes they're avidly seeking. The story moves at a runaway clip, with sharply defined, interesting characters every step of the way; a convincing plot; pungent criticism of the newscasting business; a faintly surprising climax, and a fine-tuned ear for veristic dialogue which could lighten up on that four-letter word-this author doesn't need it!
