The "Big Three" are a trio of inmates locked up in the Minnesota Security Hospital over the years, each a particularly vicious serial killer, each with his own distinct style and propensities. Everybody feels much safer knowing that they're behind bars. Except...there's a new killer on the loose. And his handiwork bears a disturbing resemblance to some of the finer points practiced by the Big Three, details that never even made the papers.

Lucas Davenport has had disturbing cases before - but never one quite like this, in the shocking new Prey work from the #1 New York Times best-selling author.

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 Naked Prey, John Sandford puts Lucas Davenport through some changes. His old boss, Rose Marie Roux, has moved up to the state level and taken Lucas with her. In addition, Lucas is now married and a new father, both of which are fine with him: He doesn't mind being a family man. But he is a little worried. For every bit of peace you get, you have to pay - and he's waiting for the bill. It comes in the form of two people found hanging from a tree in the woods of northern Minnesota. What makes it particularly sensitive is that the bodies are of a black man and a white woman, and they're naked....

The daughter of a US Senator is monitoring her social media presence when she finds a picture of herself on a strange blog. And there are other pictures...of the children of other influential Washington politicians, walking or standing outside their schools, each identified by name. Surrounding the photos are texts of vicious political rants from a motley variety of radical groups. It's obviously alarming - is there an unstable extremist tracking the loved ones of powerful politicians with deadly intent? But when the FBI is called in, there isn't much the feds can do.

Having spent two years in hiding, a big-time robber is back. It's a couple of weeks before the Republican party convention and thousands are spending cash, which is flowing into a warehouse protected by only a few armed guards. Lucas Davenport meanwhile has problems of his own, targeted by a psychopathic pimp, it's not Davenport he's after; it's his daughter.

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. Letty tells Lucas she's going to get her, and, though he suspects Letty's getting played, he volunteers to go with her....

.Lucas Davenport has seen many terrible murder scenes. This is one of the worst. In the small Minnesota town of Deephaven, an entire family has been killed - husband, wife, two daughters, dogs. There’s something about the scene that pokes at Lucas’s cop instincts - it looks an awful lot like the kind of scorched-earth retribution he’s seen in drug killings sometimes. But this is a seriously upscale town, and the husband was an executive vice president at a big bank. It just doesn’t seem to fit.

After the events in Gathering Prey, Lucas Davenport finds himself in a very unusual situation: he is no longer employed by the Minnesota BCA. His friend the governor is just cranking up a presidential campaign, though, and he invites Lucas to come along as part of his campaign staff. 'Should be fun!' he says, and it kind of is - until they find they have a shadow: an armed man intent on killing the governor...and anyone who gets in the way.

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.

A house demolition provides an unpleasant surprise for Minneapolis - the bodies of two girls, wrapped in plastic. It looks like they've been there a long time. Lucas Davenport knows exactly how long.In 1985, Davenport was a young cop with a reputation for recklessness, and the girls' disappearance was a big deal. His bosses ultimately declared the case closed, but he never agreed with that. Now that he has a chance to investigate it all over again, one thing is becoming increasingly clear: It wasn't just the bodies that were buried. It was the truth.

A daring drugs raid on a Minneapolis hospital, during which a medical orderly is murdered, takes place on the same day that Lucas Davenport's surgeon wife, Weather, is due to perform a high-profile operation to separate conjoined twin girls. Investigating the raid, Davenport concludes that it must have been an inside job and - as a witness to the criminals' desperate getaway - Weather is now in grave danger.

Layton had picked the perfect spot to lose his virginity to his girlfriend - an abandoned farmyard in the middle of cornfields. The only problem was something smelled bad... He mentioned it to a county deputy he knew, and when they looked, they found a body stuffed down a cistern. By the time Lucas Davenport was called in, the police were up to fifteen bodies and counting. The victims had been killed over many years, one every summer. How could this have happened without anybody noticing?

Virgil knows the town of Trippton, Minnesota, a little too well. A few years back, he investigated the corrupt - and, as it turned out, homicidal - local school board, and now the town's back in view with more alarming news: A woman's been found dead, frozen in a block of ice. There's a possibility that it might be connected to a high school class of 20 years ago that has a midwinter reunion coming up, and so, wrapping his coat a little tighter, Virgil begins to dig into 20 years' worth of traumas, feuds, and bad blood.

At the local state university, two feuding departments have faced off on the battleground of science and medicine. Each carries their views to extremes that may seem absurd, but highly educated people of sound mind and good intentions can reasonably disagree, right? Then a renowned and confrontational scholar winds up dead, and Virgil Flowers is brought in to investigate...and as he probes the recent ideological unrest, he soon comes to realize he's dealing with people who, on this one particular issue, are functionally crazy.
