Lester Dent wrote most of the Doc Savage novels, firmly establishing himself as a high-volume producer of pulp fiction. He made a living, but later decided to make a literary name for himself with hard-boiled crime fiction. Dent was no Chandler, but he had an interesting idea about a 1940s entrepreneur whose effort to establish a South American airline is thwarted by a corrupt senator. His attempt to get revenge (on a plane, of course) is at the bottom of a complex plot involving the senator’s daughter. Dent creates suspense but doesn’t elevate his prose or characterization above his Doc Savage novels. Not bad for pulp fiction but it doesn’t hold up well against genre classics from the same period.
