That sardonic private detective, Paul Kilgerrin, once again pulling chestnuts from the fire for Col. Mathewson of Intelligence as he jaunts off to Morocco in search of a process for gasoline and its inventor, U.S.-hating Granger. In Fex, French, German and Italian agents combine against him and hinder him, but with the help of man-without-a-country, Lassiter, and his loyal gang, Kilgerrin is more than successful -- not only in completing his mission but in the roundup of an Axis spy ring. Good and active.
