Longarm heads to a Colorado spa to clean up a killer's act! Despite his assignment to a Colorado spa, Custis Long doesn't plan on getting any R and R—he has two tasks, given to him by the Justice Department, to accomplish. The first is to keep the spa's doctor alive, and the second is to keep the son of a senator out of hot water.

Longarm’s caught between a rock and a hard place! U.S. Deputy Marshal Custis Long is dispatched to the Pass of the North—the American-Mexican border-city of northern El Paso and southern Del Norte—to extradite a prisoner from Mexico. The Federalés however, are being none too cooperative, leaving Longarm to bide his time on the American side of the city until his charge is released. Unfortunately, he learns he’s made some enemies when some polecats use him for target practice. To find out who wants him dead and why, Longarm’s got to ask questions on both sides of the border—and both sides of the law…

Longarm’s got his eyes on justice, and his hands on the Defense! As a US Deputy Marshal, Custis Long has gone after more than his fare share of trouble. But when trouble runs right into him—wearing a blood-stained night gown no less—he knows he’ll be in for quite a ride. It seems the wealthy silver mine owner Jericho Malone has just been stabbed to death in his own home, and his blood is on the night gown of his young, attractive second wife Estelle. Malone’s daughter always suspected that Estelle would sink to any level to get at their father’s money, and there’s an eye witness who swears he found her lying on the body, clutching the impaled knife in her hands. So when her defense lawyer up and collapses on the court room floor, it looks like then end of the line for Mrs. Malone. But with Longarm’s particular talent for persuading the fairer sex, Mrs. Malone has another lawyer in no time—a real fine darling of defense—and Longarm is there to make sure justice is served.

Longarm plays rough with a rancher from Reno! Rutherford Peacock has it all, looks, brains, money—and a history no one seems to know about. He’s about to become the new town Marshal of Reno, Nevada, and it’s up to him and Longarm to find out who murdered the last one. But with one eye on Peacock and another out for a killer, Longarm still finds time for an old flame. Of all the women he’s known, he never forgot the rancher’s daughter from Reno. He might just fall for the beauty—if he doesn’t have to cuff her, that is.

While south of the border, rumblings of war distract Barlow from his search for his daughter—and land him in jail as a spy.

Longarm rides south to rein in some outlaws… Longarm’s looking forward to some way-overdue R&R—but his boss has other ideas. Seems a gang of rowdy outlaws is stirring up trouble in the most untamed part of the West—a wild little settlement near the Grand Canyon. It’ll take a real pro to clean up this dirty business. So instead of kickin’ back for a little relaxin’, lusty Longarm is back on the trail. And it’s a good thing he’s decided to bring a lissome lady along for the ride. He’ll need all the help he can get—because this time, he’s in deep….

If Slocum doesn’t skidaddle, he’ll be horsemeat! If his Appaloosa hadn’t twisted its ankle on the way to Springfield, Missouri, Slocum might never have looked into buying a new horse there. He might also have missed meeting two of the prettiest cowhands ever to walk on God’s green earth. And now, he might not be running for his life… In Springfield, a man looking to buy a horse has two choices: he can go see the Tolliver brothers’ costly horses, or he can look at Linda Collins’s cheaper ones—and risk getting pumped full of lead by the Tollivers’ hired hands. So when Slocum, a stranger to the town and its rules, shows up on the wrong side of the fence, he’ll have to use his horse sense to protect the very grateful Collins sisters, not to mention stay alive himself…

Longarm better settle a land dispute—or someone might settle him six feet under… When a long-standing land dispute turns ugly down in New Mexico, the Feds send Custis Long to have a look. Somebody backshot old Tom McCabe. But just because Don Alejandro Montoya has a claim on his land, it doesn’t necessarily mean he pulled the trigger… Montoya wants McCabe’s ranch pretty bad, but he sure would like the Widow McCabe to go with it. After all, who wouldn’t want a young gal with that much money and those looks? Longarm’s got some issues to settle with Mrs. McCabe, too—but it’s not her land he’s after…

Longarm’s making a special delivery… It’s a chilly Spring in the Arkansas mountains, where Longarm is tracking down a bandit who’s robbed a passel of postmen—and just added murder to his bag of tricks. Longarm’s prepared to follow the trail wherever it leads, but he never expected Mosquito Pass to live up to its name quite the way it does. The only pleasurable part of this itchy business is the attentions of the two lonely daughters at the Widow Shreave’s cozy inn. Between the skeeters and the Shreave sisters, Longarm’ll be lucky if he’s not drained dry before he catches up with the killer…
