Someone has targeted a prominent local judge, shooting at him from a seemingly impossible distance. While the judge was not hit, his wife is severely wounded, and it is up to Joe to find answers - and the shooter.

"And see if there's any news about the missing girl." Life, as Smith used to say, is just one thing after another - as one investigation ends, a new one begins.

They find themselves delving into the seamy side of life in the town, and one of their number will have departed before this new investigation is over.

Over twenty years ago, the heiress Patricia Lockwood was abducted during a robbery of her family's estate, then locked inside an isolated cabin for months. Patricia escaped, but so did her captors - and the items stolen from her family were never recovered. Until now.

For the first time in years, the authorities have a lead - with the suitcase and painting both pointing them toward one man.

The good news is that Joe Pickett has his job back. The bad news is that he's come to learn that a drone is killing wildlife - and the drone belongs to a mysterious and wealthy man whose grandson is dating Joe's own daughter, Lucy. When Joe tries to lay down the rules for the drone operator, he's asked by the FBI and the DOJ to stand down, which only makes him more suspicious.

He begins to fear that a pack of four vicious killers working on behalf of the Sinaloa cartel known as the Wolf Pack have arrived.

Court escapes with his life and a vital piece of intelligence. Meanwhile, CIA agent Zoya Zakharova is in Berlin. Her mission: to infiltrate a private intelligence firm with some alarming connections. The closer she gets to answers, the less likely she is to get out alive.

Everything about the man is a mystery: the massive ranch in the remote Black Hills of Wyoming that nobody ever visits, the women who live with him, the secret philanthropies, the private airstrip, the sudden disappearances. And especially the persistent rumors that the man’s wealth comes from killing people. Joe Pickett, still officially a game warden but now mostly a troubleshooter for the governor, is assigned to find out what the truth is, but he discovers a lot more than he’d bargained for. There are two other men living up at that ranch. One is a stone-cold killer who takes an instant dislike to Joe.

Joe Pickett's in his last week as the temporary game warden in the town of Baggs, Wyoming, but there have been strange things going on in the mountains, and his conscience won't let him leave without checking them out: reports of camps looted, tents slashed, elk butchered.

Cody Hoyt, while a brilliant cop, is an alcoholic struggling with two months of sobriety when his mentor and AA sponsor Hank Winters is found burned to death in a remote mountain cabin. At first it looks like the suicide of a man who’s fallen off the wagon, but Cody knows Hank better than that....

The plane circled in the dark. Joe Pickett could just make out down below a figure in the snow and timber, and then three other figures closing in. There was nothing he could do about it. And Joe knew that he might be their next target. The Cates family had always been a bad lot. Game warden Joe Pickett had been able to strike a fierce blow against them when the life of his daughter April had been endangered, but he'd always wondered if there'd be a day of reckoning.
