Book Summary

The #1 international-bestselling thriller that tells the electrifying story of a police inspector and a former criminal informant in a race against time as they attempt to unravel past and present secrets.

He thought she was safe. Then the past came knocking.

Seventeen years ago, Criminal Inspector Ewert Grens was called to the scene of a brutal crime. A family had been murdered, and the only survivor--and witness--was the five-year-old daughter. The girl was placed in the witness protection program, and the case went cold, but years later, Grens is still haunted by the seemingly random slaying, and the little girl who was spared. So when he learns that the apartment where the crime occurred is now the scene of a mysterious break-in, Grens immediately fears that someone is intent on silencing the only witness. He races to find her...before they do.

Meanwhile, someone in the city's criminal underworld is executing weapons smugglers, and has placed former police informant Piet Hoffman's family in grave danger. He must unravel the secret threat to his family, all while keeping secrets of his own. Soon his hunt for answers intertwines with Ewert's, and the two men find themselves in the middle of a criminal conspiracy that is more complicated--and dangerous--than they could have imagined.

Media Reviews

"[H]eart-pounding...This terrific mash-up of police procedural and crime thriller has strongly imagined characters, explosive action, and a twisty plot with an unexpected conclusion. It's a must for Scandinavian noir fans." - Publishers Weekly (starred review)

"This tense, sophisticated procedural can stand alone, but readers will find themselves drawn to Grens' seven earlier investigations." - Booklist (starred review)

"Although Roslund deftly brings the two cases together, readers hooked by the high stakes and urgency in the early chapters may be impatient with set pieces and narrow escapes that feel like smoke...Roslund's fourth has punchy prose and plot twists that readers expecting another brooding Scandinavian noir won't see coming." - Kirkus Reviews

"A masterpiece of a thriller. Brutal, gripping, intelligent. It left me breathless." - New York Times bestselling author Liza Marklund
