The Case of the Copper King

Historical Western Cozy Mystery with a Touch of Romance


Clever and feisty Cassandra McKenzie engages her newest assignment for the Pinkerton Agency with a knack for deception and a blade in her boot. 

Smart, skilled, and unafraid to get her hands dirty, Cassandra grudgingly takes on a new assignment in one of Colorado’s busiest mining towns, where murder and theft draw her deep into a puzzle of lies, quarries, and forgery. 

When the mysterious and handsome Quinn Morgan is enlisted to help solve the case, she reluctantly accepts his presence for an undercover scheme meant to draw out the crooks and retrieve the stolen money before they end up buried in a mountainside. Will their talents be enough to untangle truth from deceit before they run out of time? 

Ride the rails to Durango at the turn of the century with Cassandra McKenzie, a woman cunning enough to solve the toughest cases in some of the Rockies most rugged and beautiful places. 

Immerse yourself in The Case of the Copper King, a stand-alone novel in the delightfully entertaining McKenzie Sisters Mystery series.

Historical Western Cozy Mystery with a Touch of Romance

A Note from MK

Dearest Reader, 

When Samantha St. Claire approached me about writing a book in the McKenzie Sisters Mystery series with her, my thoughts went back and forth between eagerness and apprehension. It was close enough in genre to most of my other westerns, yet fresh enough to intrigue me, but I also had other projects in the works. I struggled for a while, yet I would not back down because beneath the uncertainty, I felt a kinship with Cassandra and Quinn. It wasn’t until I switched the setting of her story to Durango, where I lived on a small ranch in my youth, that I really understood the character and her motives. 

I spent months researching the area as it would have been in the 1890s, which was more difficult than I had expected, and it took a bit of help to unearth some of the more stubborn historical facts. What a delight it was to revisit wonderful memories of frolicking in the hills outside of Durango, riding horses through the mountains near the ranch, and traveling north by rail along the river to Silverton. 

Cassandra’s story became mine and made me see that my love for living in the past through words began much sooner than I ever realized. I hope you enjoy reading Cassandra’s tale of adventure, mystery, and a delightful touch of romance in The Case of the Copper King.

Be well, be kind, and enjoy!

~ Mk
