Small Delights Lodge in Rocky Mountain National Park seems to be under siege. Shots fired at the owner, vehicles set on fire, boats sabotaged, electrocution booby traps, and deadfalls set up—and finally arson and murder. RMNP Ranger Tim McIntyre has plenty of suspects, including the owner of a neighboring resort, a rogue park ranger, and some Chicago mobsters who want Small Delights as a prohibition speakeasy. McIntyre's boss wants the situation resolved. The only help McIntyre can depend on consists of two attractive women, one a highly competent take-charge-and-do-it kind of gal named Polly and the other an FBI secretary with great legs and a Thompson submachine gun.
