This was Louis L'Amour's first novel published under his own name.  It was published in the United Kingdom in 1950 - the first US publication was in 1976.

Jacquine arose from the table to see her brother push his way into the room.  He waved at her over the heads of the crowd, then shouldered his way to her side.

His eyes were bright with excitement.  The rough, masculine good nature, the shouts and yells, the cracking bull whips and jingling spurs seemed to have done something to him.  Nineteen now, Barney Coyle had moved suddenly from a settled society and a regulated existence to frontier life, and for the first time he realized he was at home.  This was his life, this was for him.

"Let's go see the town, Sis!  There's no use you being cooped up in that crummy hotel room all day!  The chances are you'll never see Deadwood again, so you might as well make the most of it."

"I'm not sure," her father's voice was dubious.  This daughter of his worried him.  Barney was falling into frontier life as though born to it, and Brian Coyle was enormously proud of his son, but Jacquine defeated him.  He knew the frontier was no place for a girl, especially one as delicately nurtured as Jacquine had been.  Yet there was a sparkle in her eyes and a lift to her chin that made him uneasy.  What he had failed to understand was that she possessed just as much of the frontier spirit and his own blood as did Barney.  "I'm not sure whether it would be a good idea," he continued, "this is a rough town, and some of these men would do anything!"

"I'll take care of her!"  Barney loved his sister and was immensely proud of her.  "Anyway," he grinned at her, "if anybody got hold of her they'd wish they hadn't.  Believe me, Dad, this daughter of yours is bred back to a wildcat!"

"Barney!" she exclaimed reprovingly, but secretly the remark pleased her.  She disliked the timid females who were all ruffles and flutters.  She liked to be considered and treated as if she were self sufficient, and she knew that compared to most women, she was surprisingly so.

It had been one of the things she liked about Matt Bardoul.  He looked at her as if she were a woman, and not as if the thought of sex would shock her to the roots of her being.  He looked at her and treated her as an equal, without the usual soft talk or flattery men were always directing her way.  She had grown to dislike the immediate change that came into their voices when they started talking to her.

She was beautiful and perfectly aware of the fact.  Her common sense told her that few girls ever seemed as attractive to men as she, yet the thought did not impress her.  While aware of her beauty, it had become for her one of the accepted facts of the life she lived, like the sun coming up and the stars appearing.  The compliments it drew she received politely, but a little impatiently, for she was much more eager to be accepted and liked as a person.

It pleased her that Barney wanted her along, that he thought of her now, for she could see how the place had excited him, and how quickly he was fitting into the life around him.

The street was crowded with men.  A huge, bearded man, even larger than Buffalo Murphy, turned to stare at her, his bold eyes sweeping her up and down in mingled admiration and astonishment.  Half nettled and half amused, she stopped abruptly, put her hands on her hips and demanded, "What's the matter?  Haven't you ever seen a lady before?"
