The opening of the “Zone of Personal Security” series takes the reader into a closed world of the Internal Security Department of the Ministry of Internal Affairs, where the main character must track down “cops in league with the enemy.” The situation becomes even more complicated when professional duties intersect with personal ties, and an investigation into the murders of drug dealers points to the involvement of one of the agency’s own employees. This book reveals the life of the most closed and least popular unit of the MIA, where the work of catching traitors in uniform is thankless and extremely dangerous. Unexpected personal connections between the hunter and the target can make the case even harder—especially once it becomes known that one of those traitors may be connected to the murders of major drug traffickers.
