Cold Case Quartet

Twenty-four years ago Katharina Haugen went missing. All she left behind was her husband Martin and a mysterious string of numbers scribbled on a piece of paper.

Every year on October 9th Chief Inspector William Wisting takes out the files to the case he was never able to solve. Stares at the code he was never able to crack. And visits the husband he was never able to help.

But now Martin Haugen is missing too.

As Wisting prepares to investigate another missing persons case he's visited by a detective from Oslo. Adrian Stiller is convinced Martin's involved in another disappearance of a young woman and asks Wisting to close the net around Martin.

But is Wisting playing cat and mouse with a dangerous killer or a grief-stricken husband who cannot lay the past to rest?

Book 1 in the Wisting series.

It's been fifteen years since Simon Meier walked out of his house, never to be seen again. And just one day since politician Bernard Clausen was found dead at his cabin on the Norwegian coast. When Chief Inspector William Wisting is asked to investigate he soon discovers he may have found the key to solving Meier's disappearance. But doing so means he must work with an old adversary to piece together what really happened all those years ago. It's a puzzle that leads them into a dark underworld on the trail of Clausen's interests and vices.

Book 2 in the Cold Case Quartet series.

After four years behind bars, notorious serial killer Tom Kerr is ready to talk. And Chief Inspector William Wisting is waiting to listen.

Kerr has finally agreed to lead the police to his final victim's grave. But the expedition goes horribly wrong after his escape deep into the Norwegian forest. Wisting must launch a frantic search to find this cold-blooded killer before he strikes again. But the body of another woman, killed weeks before, has been found. Murdered in the same way as Kerr's victims.

Is there a copycat killer on the loose? Has Kerr become a twisted role model for a second killer? And, if so, what might happen if master and apprentice unite? As the clock counts down to the next murder, Wisting must put everything on the line to stop a terrifying evil before it strikes again.

Wisting is back with his most gripping case yet. In 1999, seventeen-year-old Tone Vaterland was killed on her way home from work. Desperate for a conviction the police deemed the investigation an open-and-shut case and sent her spurned boyfriend, Danny Momrak, down for murder. But twenty years later William Wisting receives a puzzling letter. It suggests the wrong man was convicted for Tone's death and the real murderer is still out there, and could kill again. . .
