Another straight forward yarn. There's been a rash of deaths involved in the construction of the Atlas skyscraper. Thanks to some sleuthing Superman finds the culprit is none other than Butch Grogan, but it turns out Grogan is simply taking orders from Nat Grayson, who's sabotaging his rivals. Bad guys get caught and Clark Kent gets the scoop.
