The body they found floating face-down in the river was wearing only underpants. If it's a fishing accident then is it a photography accident when a second corpse is discovered at a remote lake and is wearing nothing but her underwear? Ranger McIntyre's usual duties as a park ranger do not include murder--or women in underwear, for that matter--but he keeps on putting pieces of the puzzle together until they lead him to a backcountry hut and a murderer who orders him to disrobe. At gunpoint. Ranger McIntyre is also drawn into an FBI investigation. The suspect is selling salacious photographs of nudes who appear to be very, very dead. McIntyre's interaction with the FBI agent is made even more embarrassing by the fact that the agent's secretary is the "dead" gorgeous Violet Coteau, who looks like a flapper, shoots like Annie Oakley and drives like Barney Oldfield.
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.
City cops in the 1920s deal with prohibition, gangsters, loud jazz music. In Rocky Mountain National Park, Ranger McIntyre has to solve a couple of odd murders. An amateur mountaineer died hanging in his own rope on Flattop Mountain. A geologist studying stones on Flattop, ingested death camas. And a pair of odd-looking creatures on the mountain keep adding new rocks to Flattop's ancient aboriginal stone circle. McIntyre's friend is Vi Coteau, an FBI secretary in Denver, independent as an alley cat and lip-smacking gorgeous. She wants him to learn backcountry camping. McIntyre planned to go search for the source of the strange stones that are being added to the medicine circle. If he took Vi with him, it would be more of an adventure. More adventure in more ways than a backcountry ranger might imagine.
Someone found out about a painting that Albert Bierstadt left in Estes Park in the 1870s. Someone who is willing to break into summer homes looking for it, and murder anyone who gets in the way. Many of those homes lie inside Rocky Mountain National Park, which means it's up to Ranger Tim McIntyre to find out who the searcher is, why they will kill for it, and where the Bierstadt painting is hidden. Luckily the park ranger can enlist the assistance of his glamorous detective friend, Miss Vi Coteau.
In the 1920s, Rocky Mountain National Park is brand new, yet there’s already a feud going on between tour bus drivers and independent guides. One guide is found shot to death, but no one saw a gun. No one heard a shot. Then a bus driver is killed the same way. Ranger McIntyre’s glamorous lady detective friend, Vi Coteau, will investigate. Her partner, Eleanor, goes undercover and gets a job driving for the bus company. When it becomes evident that the buses are hauling something other than sightseers, our daring ranger sets the most complicated and dangerous trap of his career.
