Intrepid newsmagazine-reporter Peter Styles returns--just barely missing the Grim Reaper when the private plane of lawyer J. W. Travers explodes in midair; aboard are Travers, daughter Janet, and two grandchildren. . . but not Styles (who had a last-minute change of plan). The motive for this sabotage? Styles and Travers had been investigating the death of black, anti-nuclear activist Jefferson Fry, shot by police in a small Southern town, site of the Loring Industries nuclear plant; and Styles is now convinced that Loring's Stanley Capra not only arranged Jefferson's death (the activist supposedly resisted arrest) but also had that plane blown up. So, while being harassed and bugged and followed, Styles must get the goods on evil Capra--which he finally does with a little cherchez la femme. No mystery, the usual bland Philips prose--passable entertainment only for those with fervent anti-Big-Business sympathies.
