DETECTIVE INSPECTOR ZACK HERRY TRIES, LIKE A MODERN DAY HERCULES, TO CLEAN UP THE CRIMINAL UNDERWORLD IN STOCKHOLM. 

Four Thai women from one of the massage parlors in Södermalm, Stockholm are found brutally executed, while a fifth one is found dumped and badly mutilated outside Södersjukhuset Hospital. Marks on her body indicate that she has been attacked by an animal.

Zack Herry is the successful suburban boy who has made a career within the Stockholm police force. At night, he hangs out at clubs and sniffs cocaine with the people whom he should actually be arresting. He knows that it won’t last, but yet he cannot stop. Pursued by the internal investigators, Zack is trying to understand the driving forces behind the Södermalm murders together with his colleague Deniz. Does it involve misogyny, racism or human trafficking? One thing is for sure: more women will die unless they find the killer.

ZACK is the story of Detective Inspector Zack Herry who, like a modern day Hercules, tries to clean up the criminal underworld in Stockholm, at the same time as he is fighting the memories from a starry night with the smell of blood and grass. ZACK is the first book in a series written by author duo Mons Kallentoft and Markus Lutteman.
