Three Seconds: Ewert Grens 4 [Paperback] Roslund, Anders and Hellstrom, Borge

A Polish ex-con named Piet Hoffmann gets one impossible job: go undercover in Sweden's most brutal maximum-security prison to infiltrate the Polish mafia's drug operation. Three seconds — that's how long he has to make a life-or-death decision when his cover starts to crack. Meanwhile, Detective Ewert Grens is hunting the same organization from the outside, with no idea the man inside is working for Swedish intelligence. When the operation collapses, Hoffmann is trapped behind bars with criminals who'd kill him in a heartbeat if they knew the truth. Roslund and Hellström ratchet the tension to unbearable levels, delivering a Scandinavian crime thriller that's as politically sharp as it is visceral. Fourth in the Grens series, but stands alone. For fans of Jo Nesbø who want their Nordic noir claustrophobic, morally murky, and impossible to put down.
