If you recognize the name Albert Fountain, you’ll almost certainly associate him with his disappearance in the New Mexico desert in 1896 along with his eight-year-old son. And that’s probably almost everything you know about the man.

But Fountain’s disappearance happened as the result of events that took place well before that early February day. In fact, he’d been a polarizing figure in southern New Mexico for a number of years. He’d defended Billy the Kid in court and made other decisions that brought attention to himself—and not necessarily in a good way.

Mary Armstrong’s novel The Mesilla provides a fictional account of some of the events in Fountain’s career prior to his disappearance. This story, the first in Armstrong’s Two Valleys Saga series, centers around Fountain’s defense of Bronco Sue, a woman who was accused of killing her husband, one of a series of men she’d cohabitated with. The courtroom scenes alone are worth the price of this book.

Armstrong has clearly done her homework. The novel is packed with information and anecdotes about New Mexico’s Mesilla and Tularosa Valleys in the late 1800s, which she feeds seamlessly into the story line. If you’re interested in the history of these areas or are just looking for a well-written historical novel, I recommend The Mesilla.
