When a United States marshal retires their badge and hangs up their gun, more often than not, their only remaining desire is to ride off into a distant horizon and live out the remainder of their lives in peace and solitude. When Oliver Blackstone sailed from Galveston, Texas, to Boston, Massachusetts, it was also his deepest wish. After bringing an untold number of the Western Frontier's most dangerous criminals to justice and sending more than 100 of them to face judgment in the hereafter, he'd been dubbed "The Deadliest Man Alive" by renowned frontier journalist J.C. Cavanaugh, and reigned supreme at the top of "The List" for more than a decade.

While his intention was to fade into the setting sun and begin anew, far from the territory where his legend had been born, everything changed the moment he met Sarah Hutchins on the steps of the bank, mere hours after arriving in Boston. Faced with such an overwhelming and mutual attraction, Oliver was prepared to amend his carefully laid plans to make room for this unexpected thief of his heart. Unfortunately, her father, Leonard Hutchins, wasn't nearly as enamored with the idea as Oliver and his daughter were, and in his attempt to keep them apart, he would dredge up the demons that Marshal Oliver Blackstone thought he'd permanently laid to rest along with his legendary Colt Walker 1847.

The thing is, some spirits are restless, and no matter how deep you bury them, they will eventually claw their way back to the surface to remind you of who you were, who you are, and who you will always be. With an indomitable spirit like that of Marshal Oliver James Blackstone, only a fool would believe it could remain buried for long.
