Four Thai women are brutally murdered in an apartment outside of Stockholm. They all worked at the same massage parlor, and connections are made to the sex trade. Shortly thereafter, two more women are found killed in another massage parlor. Their colleagues witness of slave-like conditions and of a house in the woods where young girls are kept. The police realize they must find the house before more innocent women are killed.

Zack Herry is put on the case and seeks out the owner of the massage parlor, a woman named Sukayana Prikon. Sukayana points the police in the direction of an MC-gang called Brotherhood that moonlights as a recruitment service to bring Thai women to Stockholm. The next day Sukayana is found unconscious outside a hospital, her legs brutally mutilated by what at first seems to be dogs – but later proves to be wolves. The cruelty speaks of an unusually brutal and callous perpetrator and Zack blames himself for not protecting Sukayana; had he acted differently, he could have saved her.

Several suspects surface. Peter Karlsson, a wealthy businessman with a racist online alterego who is extremely vocal about his hate against immigrants, especially Thai women. Perhaps the Turkish gang Yildizyeli? Or the MC-gang Brotherhood? When Zack and Deniz confront Brotherhood, they are met with gunshots. The bikers had obviously been waiting for someone – but whom? And what is the link to the brutal murders?

In Zack, Stockholm is plagued by gang showdowns, human trafficking, and corrupt businessmen, all against the backdrop of a tantalizing Swedish summer. Zack is the first crime novel by Mons Kallentoft and Markus Lutteman in collaboration. It is the first in a successful series featuring the brilliant Zack Herry, modern-day Hercules and unconventional star of the Stockholm police force.

”Fallible, fullbodied characters drive an absolutely riveting plot by acclaimed crime-fiction writer Mons Kallentoft in collaboration with biographer Lutteman. Top-notch Swedish noir.”

”Zack is a very intriguing guy. He hails from a poor background, he plays on both sides of the law, and he is both young and bold. Combined, this gives the series spectacular momentum. And as most of the time when Kallentoft writes, his prose is solid: it is poetic, it is sharp.”

“Fast-paced, well written, and sometimes a little too disconcerting.”
Lotta Olsson, Dagens Nyheter (SE)
