Calamitytown — J.R. Roberts

In Boulder, Colorado, Clint Adams ran into his old friend Martha ‘Calamity Jane' Canary. Now in her late thirties, Jane was married and running a boarding house. But staying on as one of Jane's guests brought back memories Deadwood, South Dakota in 1876, when their friend Wild Bill Hickok was shot in the back and killed.
It seemed that the past wouldn't stay buried, and just to prove it, violent death suddenly reared its ugly head all over again. The Boulder Police Department asked Clint to help solve the murder, but he had his hands full just dealing with a gunfighter who was determined to meet him through gunsmoke.
Still, when Clint wasn't bedding the ladies â€" including Calamity Jane herself â€" he set out to find Boulder's mysterious killer … and the answer he came up with surprised even The Gunsmith himself.
