They call them Travelers. They move from city to city, panhandling, committing no crimes - they just like to stay on the move. And now somebody is killing them. Lucas Davenport's adopted daughter, Letty, is home from college when she gets a phone call from a woman Traveler she'd befriended in San Francisco. The woman thinks somebody's killing her friends, she's afraid she knows who it is, and now her male companion has gone missing.

Lucas Davenport's first case as a US marshal sends him into uncharted territory in the thrilling new novel in the number one New York Times best-selling series. Thanks to some very influential people whose lives he saved, Lucas is no longer working for the Minnesota Bureau of Criminal Apprehension but for the US Marshals Service, and with unusual scope. He gets to pick his own cases, whatever they are, wherever they lead him.

Clayton Deese looks like a small-time criminal, muscle for hire when his loan shark boss needs to teach someone a lesson. Now, seven months after a job that went south and landed him in jail, Deese has skipped out on bail, and the US Marshals come looking for him. They don't much care about a low-level guy - it's his boss they want - but Deese might be their best chance to bring down the whole operation. Then, they step onto a dirt trail behind Deese's rural Louisiana cabin and find a jungle full of graves.

The night after the fourth of July, Layton Carlson, Jr., of Red Wing, Minnesota, finally got lucky. And unlucky.

He’d picked the perfect spot to lose his virginity to his girlfriend, an abandoned farmyard in the middle of cornfields: nice, private, and quiet. The only problem was...something smelled bad - like, really bad. He mentioned it to a county deputy he knew, and when the cop took a look, he found a body stuffed down a cistern. And then another, and another. By the time Lucas Davenport was called in, the police were up to 15 bodies and counting.

Pinion, Minnesota: a huge city of all of 700 folks who define the phrase ‘small town’. Nothing has ever happened in Pinion, and nothing ever will...until the mayor of sorts comes up with a scheme to put Pinion on the map. He’s heard of a place where a floating image of the Virgin Mary turned the whole town into a shrine, attracting thousands of curious people and making the townsfolk rich overnight. Why not stage a prank in Pinion and do the same? What could go wrong? And then a dead body shows up. 

Virgil Flowers kicked around for a while before joining the Minnesota Bureau of Criminal Apprehension. First it was the army and the military police, then the police in St. Paul, and finally Lucas Davenport brought him into the BCA, promising him, "We'll only give you the hard stuff." He's been doing the hard stuff for three years now, but never anything like this.

Virgil Flowers heads north to solve a puzzling murder - and finds that the country is very rough indeed. While competing in a fishing tournament in a remote area of northern Minnesota, Flowers gets a call from Lucas Davenport asking him to investigate a murder at a nearby resort, where a woman has been shot while kayaking. The resort is for women only: a place to relax, get fit, recover from plastic surgery and commune with nature. It's also hotbed of jealousy, blackmail, greed, anger, and fear.

One late fall Sunday in southern Minnesota, a farmer brings a load of soybeans to a local grain elevator - and a young man hits him on the head with a steel bar, drops him into the grain bin, waits until he's sure he's dead, and then calls the sheriff to report the "accident." Suspicious, the sheriff calls in Virgil Flowers, who quickly breaks the kid down...and the next day the boy's found hanging in his cell. Remorse? Virgil isn't so sure....

Flowers is only in his late 30's, but he's been around the block a few times, and he doesn't think much can surprise him anymore. He's wrong. It's a hot, humid summer night in Minnesota, and Flowers is in bed with one of his ex-wives (the second one , if you're keeping count ) when the phone rings. It's Lucas Davenport. There's a body in Stillwater, two shots to the head, found near a veterans' memorial. And the victim has a lemon in his mouth.

Very early one morning, a Minnesota political fixer answers his doorbell. The next thing he knows, he’s waking up on the floor of a moving car, lying on a plastic sheet, his body wet with blood. When the car stops, a voice says, "Hey, I think he’s breathing." And another voice says, "Yeah? Give me the bat." And that’s the last thing he knows. Davenport is investigating another case when the trail leads to the man’s disappearance, then - very troublingly - to the Minneapolis police department, then - most troublingly of all - to a woman who could give Machiavelli lessons.

Bonnie and Clyde, they thought. And what's-his-name, the sidekick. Three teenagers with dead-end lives, and chips on their shoulders, and guns. The first person they killed was a highway patrolman. The second was a woman during a robbery. Then, hell, why not keep on going? As their crime spree cuts a swath through rural Minnesota, some of it captured on the killers' cell phones and sent to a local television station, Bureau of Criminal Apprehension investigator Virgil Flowers joins the growing army of cops trying to run them down.

In Israel, a man clutching a backpack searches desperately for a boat. In Minnesota, Virgil Flowers gets a message from Lucas Davenport: You're about to get a visitor. It's an Israeli cop, and she's tailing a man who's smuggled out an extraordinary relic - a copper scroll revealing startling details about the man known as King Solomon. Wait a minute, laughs Virgil. Is this one of those Da Vinci Code deals? The secret scroll, the blockbuster revelation, the teams of murderous bad guys? Should I be boning up on my Bible verses? He looks at the cop. She's not laughing.

In a wealthy Minneapolis neighborhood, two elderly women are bludgeoned to death. They are apparent victims of a random robbery, though nothing of value appears to have been stolen. But when Lucas Davenport looks deeper, he fears that the victims weren’t so random, and the items stolen were far from invaluable. As a pattern emerges it leads Lucas to...certainly not where he expected. Which is too bad, because the killers are expecting him. And that’s only the first surprise.

In Southeast Minnesota, a school board meeting is coming to an end. The board chairman announces that the rest of the meeting will be closed due to personnel issues. Issues is correct. The proposal up for a vote is whether to authorise the killing of a local reporter. Meanwhile, Virgil Flowers is helping out a friend by looking into a dognapping when he gets a call from Lucas Davenport. A murdered body has been found, and the victim is a local reporter....

The first storm comes from, of all places, the Minnesota zoo. Two large and very rare Amur tigers have vanished from their cage, and authorities are worried that they’ve been stolen for their body parts. Traditional Chinese medicine prizes those parts for home remedies, and people will do extreme things to get what they need. Some of them are a great deal more extreme than others - as Virgil is about to find out. Forget a storm...this one’s a tornado.
